mnimer / dphibernate Goto Github PK

Can be configured to support dphibernate with JPA, persistence.xml and an
existing connection settings? thanks

This block in ProxyLoadService is incorrect:

        if (id instanceof String)
        {
            @SuppressWarnings("unused")// For debugging...
            String originalId = (String) id;
            id = Integer.parseInt((String) id);
        }

We shouldn't be blindly casting id's Int -> String, as many id's will be 
Strings.

WORKAROUND:
Comment out this block ( 33 - 38 ).

Need to fix this.

I believe this was added because integer ID's were arriving at this method as 
Strings.  I need to either understand why they were being incorrectly cast as 
Strings originally, or investgiate the daoClass param to understand which type 
the ID is expecting.

It looks as though deserialized objects can 
 * incur unrequired trips to the db
 * not honour updated properties sent from the client.

This needs investigation, as I don't know the deserializer code well enough ATM 
to know for sure what the current / expected behaviour is.

Initial email conversation pasted below:

So, your method conceptually looks something like this?

public class SavePersonRequest()
{
    var person:Person;
    // Other stuff
}

This is not currently supported out-of-the-box, that I'm aware of.  (I 
haven't spent a great deal of time in the Deserializer, but I can take a 
look).
I guess what the deserializer should do is grab the person instance out of 
the hibernate cache (or, if it's been flushed, we'll need to re-load it), 
and copy populated properties over from the instance received in the server 
call.

I can see some challenges ahead in differentiating the meaning of null 
values between that of a uninitialized proxy, and one where the value has 
subsequently been set to null on the client.

I'll raise a ticket to track the discovery & dev of this feature.

What steps will reproduce the problem?
1. Create a VO with a Set (HashSet) instead of an Array List
2. Try to persist the VO on the server-sode

What is the expected output? What do you see instead?
Should persist the Java VO.
Instead, get:
java.lang.IllegalArgumentException: argument type mismatch 

What version of the product are you using? On what operating system?
1.0.17 Jar
Windows XP

Please provide any additional information below.
See
http://groups.google.com/group/dphibernate/browse_thread/thread/7e9e80dfe05e59f5
/aa25ab09237060ba
for more information including a possible solution

What steps will reproduce the problem?
1. define transient methods in hibernate entity (only setter or getter)
2. when object is transleting it,s thows NPE on line:
pd.getReadMethod().invoke();
           ^^^null.invoke();
(when entity contains only setter of property pd)

or
pd.getWriteMethod().invoke();
           ^^^null.invoke();

(when entity contains only getter of property pd)

error in classes:
HibernateSerializer - 189
HibernateDeserializer - 186,190

version:
dpHibernate1.0.13

What steps will reproduce the problem?
1. Create a new object
2. Set some variables inside
3. try to read one of the variables

getProperty(obj:IHibernateProxy, property:String, value:*):* {
            var ro:IHibernateRPC;
            var entry:HibernateManagedEntry = hibernateDictionary[ obj ] as
HibernateManagedEntry   
            ro = entry.ro; -- Throws -->
TypeError: Error #1009: Cannot access a property or method of a null object
reference.

What steps will reproduce the problem?
1. save bugs
2.
3.

when dpHibernate save pojo object,it will load all associated object.

I might be wrong. But there is no way to use the mxml to configure result
functions for each method. Like this:

<mx:RemoteObject id="srv" destination="service">
    <mx:method name="login" result="onTryLoginResult(event)"/>
    [...]

This would be very handy. 

 While trying to send an TS_Project object to Java, i get a Cannot invoke
method ''. Method '' not found error. The function is straightforward :

    public TS_Projekt mergeProjekt(TS_Projekt P)
    {       
        super.merge(P);
        return P;
    }

What steps will reproduce the problem?
1. read entity, that have empty collections
2. on client instances of collections is idential

bugs: when puts objects in cache (clases HibernateSerializer and
HibernateDeserializer)
empty Lists or Sets have idential hashcode, => different instanses of empty
List or Sets are idential on HashMap.

solution:

use System.identityHashCode for idential objects but not hashcode.

Object key = new ObjHolder(getCacheKey(obj));  
...
cache.put(key, list);

---

public class ObjHolder {      
    private Object obj;

    public ObjHolder(Object obj) {
        this.obj = obj;
    }

    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        ObjHolder objHolder = (ObjHolder) o;
        return !(obj != null ? !obj.equals(objHolder.obj) : objHolder.obj
!= null);
    }

    public int hashCode() {
        return System.identityHashCode(obj);
    }
}

version:
dpHibernate1.0.13

two bugs:
1. If i create new instance of hibernatebean's sub class,happen getter 
exception.
2. When hibernate pojo has java.util.HashSet/Set,happen CastException

Hello!!
When table’s primary key isn’t String type(etc Long type),Lazy data sub 
object is NaN.

dpHibernate isn’t support many-to-many

What steps will reproduce the problem?
1. why ActionScript don't use Hibernate lazy!!!!
example: var name:String=User.Department.name
         when first time,name have not value!!

I have 2 Hibernate Pojo's named "Parent" and "Child".  Parent lazily loads
its relationship to Child.  When I retrieve a Parent in ActionScript the
object has a relationship to the Child proxy.  If I change an attribute on
Parent and then attempt to perist the Parent object, I get a foreign-key
exception because the id of the Child object is 0 when the save is
attempted on the sever (correcsponding to the NaN value on the ActionScript
proxy).  It appears that when the remote call to save the Parent is made,
an attempt to initialize/load it's Child object from the remote server is
made.  However, prior to completing the initialization the call to the
Remote save method is made sending a Parent object with an uninitialized
Child.  It seems like this might be a result of the fact that the remote
calls are asynchronous and are executing in parallel rather than serially.

Have you seen this before.  Any insight would be helpful.

Thanks,

Dave

What steps will reproduce the problem?
1. when reading entity it's throws:
[CachedConnectionManager] Closing a connection for you. Please close them
yourself: org.jboss.resource.adapter.jdbc.Wrap
pedConnection@15b25a1

class HibernateSerializer contains native sql code on lines 431-453, that
is repeate fine code on lines upper in method.
deleting this code and uncomenting line 429 is resolving problem:

List hibernateResults = q2.list(); 
return hibernateResults;

version:
dpHibernate1.0.13

In 
net.digitalprimates.persistence.hibernate.utils.filters.HibernateSessionServletF
ilter the 
HibernateUtil from 
net.digitalprimates.persistence.hibernate.utils.HibernateUtil is being used and 
causing a new instance of Hibernate to start at every request.

Suggest providing an interface so that users can roll their own version 
HibernateUtil (i.e. utilizing 
Spring, etc.).

What steps will reproduce the problem?
1. Checking it out and run it
2. resetDB -> load carts -> click on cart -> click on Item
3. then modify the name of the shown item -> save Item

What is the expected output? What do you see instead?

after that the cart list loads again. If I click on the same cart the items
name did not change !


What version of the product are you using? On what operating system?

Windows XP, newest build of the dphibernate JAR. 


Please provide any additional information below.

the method on the server to "merge" the modified item gets called.
everything right. if the item is refreshed from the client the old one
(still in the database gets passed forward). 

the only solution I got so far is to call explicitly in the DAO
sessionTemplate.flush(). But if I modify a lot of objects the performance
would go down in that case.

I share my experience with "samples_springSample1". It works pretty well
but I got problem when I tried to save an item. I'm not sure if it the best
way to fix merge Item but it solves my issue.

IN
com.universalmind.hStore.data.ItemDAO : public Item merge(Item item)

ADD
getHibernateTemplate().flush();

SO

public Item merge(Item item){
    Item _item = (Item) getHibernateTemplate().merge(item);
    getHibernateTemplate().flush();
    return _item;
}

Any idea why this issue? Maybe should not happen and then let me know some
reasons why I must do it ^^

What steps will reproduce the problem?

1. Having a Java entity class with a property of type java.util.Set (with
java.util.List it works fine)
Example:
public class Cart extends HibernateProxy implements Serializable  {
 private Set items = new HashSet(0);
}

2. In your flex application, call a service method which take this entity
as a parameter.
Example:
srv.createCart(new Cart());


What is the expected output? What do you see instead?

The Cart Object (and particularly the items property) is not well
deserialized and dpHibernate throws this exception:
java.lang.IllegalArgumentException: argument type mismatch

Bean(HibernateDeserializer.java:214)
...


What version of the product are you using? On what operating system?
Spring 2.5, Hibernate 3.2, Ubuntu operating system


Please provide any additional information below.

I think the problem comes from the "readCollection" method of the
"HibernateDeserializer" class.
During the deserialization process, the property of type Set is processed
by the "readCollection" method (because the Set type is also of type
Collection).
In this method the property is transformed into an ArrayList which then
cause an error of "IllegalArgumentException" when the method try to cast
the translated property of type ArrayList in a Map type.

I resolved the problem by modifying the "readCollection" method like that:

for (Object o : (Collection) obj)
{
 o = translate(o, type);
}
return obj;

Like this, the type of the property (of type Collection) is not changed and
the error don't occurred !

Hope this could help.
Bye.

As I explain on the google group the lazy loading doesn't seems to work as soon 
as i put dphibernate, I'm not sure if it's a bug or a configuration problem. 

For more details:
http://groups.google.com/group/dphibernate/browse_thread/thread/b670e86f51bd600f

What steps will reproduce the problem?
1. Open any existing dphibernate sample project
2. Add some spaces, tabs or new lines in <class>...</class> and/or
<getCurrentSessionMethod>...</getCurrentSessionMethod> just before and/or
after the text values.
3. Try call a HibernateRemoteObject.

What is the expected output? What do you see instead?
It will raise a ClassNotFound exception on the server side, saying that the
right Session Factory class you've configed in remoting-config.xml cannot
be found.

What version of the product are you using? On what operating system?
This happens in the current version on windows xp sp2 (which is my
platform). But obviously this will effect all platforms.

Please provide any additional information below.
I'm pretty sure this happens because dphibernate doesn't parse the
remoting-config.xml in a right way. It fetches the text node without
removing the leading and trailing spaces. I'm not saying having leading or
trailing spaces in xml text node is a good behavior. But this is a common
case if someone use a xml formatter in order to get a prettier look of
his/her xml files.

What steps will reproduce the problem?
1. Using auction site, lazy-loading of AuctionLot objects appears to be 
returning only the first character of the GUID value in for the data being 
retrieved from the database.

What is the expected output? What do you see instead?
Expected output is a 36-character guid value.  Getting a 1-character 
string instead.

What version of the product are you using? On what operating system?
Lastest dpHibernate build is being used on Windows Vista.

Please provide any additional information below.
Try replicating this issue with our video/chat application issuing the 
GetAllCommand.

After converting to use dpHibernate, I am unable display png images of
ByteArray.  My question is whether this data is supported i.e. java byte[]
-> AS3 ByteArray.  Or I am missing something in my setup.

Thanks.
JT

What steps will reproduce the problem?
1. I'm trying to use HibernateAdapter as default adapter in my project with
spring+hibernate framework. Hibernate returns List<Object[]> from hql but
the hibernate adapter returns ArrayCollection<null> objects to AS.

What is the expected output? What do you see instead?
Expecting to see ArrayCollection<Arrays> but it returns ArrayCollection<null>

What version of the product are you using? On what operating system?
dpHibernate1.0.11.jar

Please provide any additional information below.
I modified the HibernateSerializer's translate method to check for
isArray() and write the array similar to collection with an additional
"writeArray" method.

The above modification works and the array is translated fine.

Attached is the modified HibernateSerializer.java file. Let me know if this
is fine. 

What steps will reproduce the problem?
1. Add name 
2.  Add number for sku
3.  Click save button

What is the expected output? What do you see instead?
Expected to save and round-trip to server.  See only handshake.

In net.digitalprimates.persistence.hibernate.HibernateManaged  the
manageChildHibernateObjects function is checking for accessors in
describeType( object ), which misses out variables, which results in entry
becoming null in the getProperty function, if a variable is not a simple
object but a HibernateBean.

Workaroud: add accessors to variables.

Given a typical parent-child relationship, accessing parent.child() will 
correctly lazy-load the child object from the server.

However, a subsequent call to child.parent() will trigger another load of 
parent, despite it already being present on the client.

We should be smarter about this, and only load single instances of objects to 
the client.

What steps will reproduce the problem?
1. Attempt to sort a lazy-loaded set utilizing an "order-by="columnName
asc"" directive in the hibernate mapping file.

What is the expected output? What do you see instead?
The expected output is that lazy-loaded object should be ordered based on
the order-by argument supplied for the <set> definition in hibernate. 
Instead, it appears that the objects are not being sorted at all since they
are lazy-loaded and the property that sorting should be evaluating has not
been initialized.

What version of the product are you using? On what operating system?
dpHibernate1.0.9.jar

Currently pagination support is defined as a property on the 
HibernateSerializer.

This is confusing, and makes having multiple pagination settings for a single 
project difficult, if not impossible.

This should be moved to a setting on either the adapter or the destination, to 
allow more fine-grained control over this setting

I downloaded your dpHibernate source and followed the config. The source 
compiled fine. When i debug the app and put break points on the register user, 
it dies on    = new HibernateBean. It reports it as being missing / null 
object. Let me know what i need to fix.

What steps will reproduce the problem?
1. On the HibernateService I call super.list(Entity.class);
2. The hibernate execute a simple query like this "select * from entity"
3. This entity have relation one-to-many

What is the expected output? What do you see instead?
The result is OK

What version of the product are you using? On what operating system?
dpHibernate1.0.13.jar. OS Windows XP.

Please provide any additional information below.
The result of the query is OK.

What steps will reproduce the problem?
1. create a java service method that returns array type to Flex
2. call this service method from flex and assign the results to
ArrayCollection.
3.

What is the expected output? What do you see instead?
Flex side ArrayCollection should be populated with the data from java
service, but it returns null value.

What version of the product are you using? On what operating system?
latest (1.0.17)

Please provide any additional information below.

HibernateSerializer doesn't validate the array type. Fix for this issue as
below...

Class: HibernateSerializer
Method: private Object translate(Object obj)

Change the following piece of code
===================================
else if (obj instanceof Object 
                && (!isSimple(obj)) 
                && !(obj instanceof ASObject) 
                )
        {
            result = writeBean(obj, result, key);
        } 


===================================

to

==================================
else if (obj instanceof Object 
                && (!isSimple(obj)) 
                && !(obj instanceof ASObject) 
                && !isArrayType(obj.getClass()))
        {
            result = writeBean(obj, result, key);
        } 
==================================

Create a new method isArrayType

================================
private boolean isArrayType(Class desiredClass)
    {

        if (desiredClass.isArray())
        {
            return true;
        }
        else
        {
            return false;
        }       
    }
================================

What steps will reproduce the problem?
I have used cxf to wrap some domain objects which inherit from
HibernateProxy, and found that cxf cannot start due to multiple instances
of the same property. 

This can be modified by changing the members:
    public Object proxyKey;
    public Boolean proxyInitialized = true;
to private, and relying on accessors to modify them.


What version of the product are you using? On what operating system?
dpHibernate 1.0.17 (and recent svn) on mac os x


Please provide any additional information below.

This should be a relatively simple change, which will make the system
easier to integrate.

What steps will reproduce the problem?
1. Create hibernate VO that has a deep hierarchical structure.  One object
has a list of many managed objects, which each have lists of many other
managed objects, etc.
2. Send the most senior VO (the one that has no parent objects) from Flex
to the Java data service manager.

What is the expected output? What do you see instead?
Objects are de-serialized and ready of use in the Java service manager.  I
indeed see the objects there, but the de-serialization process takes a long
time (as seen from the dpHibernate de-serialization timer output).

What steps will reproduce the problem?
1. Flex VOs use ListCollectionView instead of ArrayList
2. Do a Hibernate create() on the server side


What is the expected output? What do you see instead?
Expected to save to database

What version of the product are you using? On what operating system?
dpHibernate1.0.1.swc

Please provide any additional information below.
In HibernateManaged.as:manageChildHibernateObjects() change ArrayCollection
to ListCollectionView


else if ( object is ArrayCollection ) {
                for ( var i:int=0;i<object.length; i++ ) {
                    manageChildHibernateObjects( object[ i ], object, String( i ), ro ) 
                }

Hello, 

the first thing is to comment that I am sorry if my language is not quite 
correct, since my level of English is not very good.

The problem comes when you run the tool profile of Flex and see that all the 
classes that extends HibernateBean and [Managed], the GC is not able to remove, 
and therefore, this error affects the performance.

Any solution?

Thanks for the reply and for developing the project.

What steps will reproduce the problem?
1. Just use HibernateRemoteObject to request a non hibernate data. In
exactly my case, a int value.

What is the expected output? What do you see instead?
I think the expected result some the the int value itself. Or if you
request a POJO (with none hibernate stuff), it should simply return the
POJO itself. But for now, HibernateRemoteObject will return an ObjectProxy
and the internal value of this returned object is null.

What version of the product are you using? On what operating system?
I'm using the current version with Fle 3 + Spring 2.5.3 + Hibernate Core
3.2.6 + Hibernate Annotation 3.3.1 on Window XP SP2.

Please provide any additional information below.
I think dphibernate's server side code should check if an object to be
returned is related to hibernate. If not, it should simply return the plain
object itself instead of a proxy object.

What steps will reproduce the problem?
1. define Set-based (not List-based) collections in hibernate entity
2. when object is deserializing it's throws error

error in class HibernateDeserializer:

        private Object readCollection(Object obj, Class type)
        {
                //create always ArrayList
                //type is ignored
                List items = new ArrayList();
                Iterator itr = ((Collection) obj).iterator();
                while (itr.hasNext())
                {
                        Object o = itr.next();
                        Object newVal = translate(o, type);
                        items.add(newVal);
                }
                return items;
        }

Class of "items" must be class of variable "type"

version:
dpHibernate1.0.13

What steps will reproduce the problem?
1. Create a lazy class with a <list> element set to lazy=true
2. call from flex and watch the console
3.

What is the expected output? What do you see instead?
expected to see serialized output, but error produced is:

expected type: java.util.ArrayList, actual value: 
org.hibernate.collection.PersistentList

What version of the product are you using? On what operating system?


Please provide any additional information below.

What steps will reproduce the problem?
1. Return a java Set object from a remote destination
2. Assign a to a flex variable

var testCollectionConversion:ArrayCollection = (event.result as
ArrayCollection);


What is the expected output? What do you see instead?
Expected testCollectionConversion to be populated with the items from the
Java set.  I get a null value returned.

What version of the product are you using? On what operating system?
Windows XP
dpHibernate-1.0.17

Please provide any additional information below.
I use a work around of wrapping a list around the set before I return it
and it works fine.  Shouldn't have to do that though.  Set is just a list
with no duplications.
http://java.sun.com/javase/6/docs/api/java/util/ArrayList.html#ArrayList(java.ut
il.Collection)

Composite Keys are not currently supported.

This change is non-trivial, and we would need to consider the impact in several 
places:

IHibernateProxy assumes the key is a single value
getPks() method of HibernateSerializer currently treats all keys as a single 
value

Currently, support for custom serializers / deserializers is limited.

Because this is externalized through the spring context, we should support 
users registering their own implementations.

Things to consider:
 * Currently, the entity to serialize on the serializer is immutable.  I don't want to change this.

When I have dphibernate configured I cant use others BeanProxy registred 
through BlazeDS.

Means to reproduce:

I have a file attached that must used to Serialize Enum type that have a 
property named "descricao".

I've created a JPA object with a property mapping to a specific Enum. When I 
send this to Flex it will enter on Bean Proxy and create a map with all Enum 
properties. When I send it back to Java it will read the ASObjects properties 
and map back to the specific Enum.

When I have dpHibernate active it will occurs two errors:

The first is that the registered bean proxy (attached) is not called anymore.

The second is the following error that could be corrected easily:

java.lang.NullPointerException
    at net.digitalprimates.persistence.translators.hibernate.HibernateDeserializer.readBean(HibernateDeserializer.java:191)
    at net.digitalprimates.persistence.translators.hibernate.HibernateDeserializer.translate(HibernateDeserializer.java:119)
    at net.digitalprimates.persistence.translators.hibernate.HibernateDeserializer.readBean(HibernateDeserializer.java:190)

What steps will reproduce the problem?
1. Set up two tables (A and B) with a many-to-many relation between them
2. One of these tables (or both) must have a composite primary key (here A)
3. Try to lasy load the set of A from an entity B

What is the expected output? What do you see instead?
Instead of a set of A entity, for each call to the remote function
load(clazz=A.class, proxyKey=key) produce this kind of exception :
"org.hibernate.TypeMismatchException : Provided id of the wrong type
for class model.Ecoprocess. Expected: class model.EcoprocessId, got
class java.lang.Integer"


What version of the product are you using? On what operating system?
dpHibernate 1.0.17. Windows Vista 64.

Please provide any additional information below.

The problem seems to be in getPkIds from HibernateSerializer.java
Type t = persister.getKeyType();
PreparedStatement stmt =
((SessionImpl)session).connection().prepareStatement(sql);
if( t instanceof StringType ){
    stmt.setString(1, collection.getKey().toString());
}
else {
    stmt.setObject(1, new Integer(collection.getKey().toString()).intValue());
}

"t" is converted to an integer if it's not a String. What if it's an
composite key entity ?


Attached files : Category and Ecoprocess, my two concerned entities, and
the composite key EcoprocessId.

What steps will reproduce the problem?
1. Create server using Spring, Hibernate and any database.
2. Create client using Flex, Actionscript 
3. On the server side create an entity User with different properties and a 
property Role as well
4. Create on the server side the entity Role.
5. Make collection of Role in the entity User and set Lazy to it.
6. Configure the brige between the server and the client using dpHibernate (as 
in the sample spring_sample1) and in the article "Get start".
7. Create a table where you'll be able to see the output and get user's role 
list from the server.
8. Run your application.
9. At first touching loadDPProxy request would be initialized with Proxy object 
Role ( as many requests will be initialized as big collection is) 

What is the expected output? What do you see instead?
Expected to see the user's role collection, instead I see that a responce has 
all filled entities. But my entity on the client side is still empty. 

What version of the product are you using? On what operating system?
dpHibernate 1.0.17, Windows 7

Please provide any additional information below.
Looks like setProperties() method from HibernateManaged.as doesn't work 
correctly with custom properties. I think so because "proxyKey" and 
"proxyInitialized" fields are change there state after lazy-loading and it 
works. I see the filled object in the responce. 

Hi all,

First of all, thanks to everyone involved for the effort going into this
much needed project. 

I'm not sure if I'm missing something or if this is indeed a bug: I'm
getting a NullPointerException during serialization in response to a call
to a Spring bean; otherwise, the call to the method in question appears to
be successful.

Attached is complete source code for a (small) Eclipse project designed to
test lazy loading with dpHibernate. The only changes required to run the
code are to modify the database settings (in
WEB-INF/spring/applicationContext-db.xml and hibernate/hibernate.cfg.xml)
and add a test record to the "Parent" table.

Please let me know if you have any questions.

Thanks,
James

been invalidated.

What steps will reproduce the problem?
1. Created a hibernate VO with a transient method that doesn't follow
getter/setter method naming convention (e.g. public boolean isNewCustomer() )
2. Flex gets this vo and updates some information.
3. Flex tries to save this updated vo by calling service method

What is the expected output? What do you see instead?
I expected this method won't be invoked by readBean(Object obj) method in
HibernateDeserializer class.

What version of the product are you using? On what operating system?
1.0.9 on WindowsXP

Please provide any additional information below.
pd.getWriteMethod() returns null because there is no matching setter method
for this (isNewCustomer()) and null pointer validation is missing for statement

pd.getWriteMethod().invoke(obj, newVal);

error in proxyKey if it is null


please add 

if ( __proxyKey != null )

in HibernateBean.as:38


-----
public function set proxyKey( value:Object ):void {     
            if ( __proxyKey != null )
                StateRepository.removeFromNewEntityList( __proxyKey.toString() );
            __proxyKey = value;
        }
_____

What steps will reproduce the problem?
1.Populate AS3 VO
2.Send To Java
3.Deserialize in Java

I´ve populate my variable typed Date with "18/01/2010" and recieve in Java 
"17/01/2010".

I saw in source code the function called populateBean and this function uses 
.getTime(). I know that function in AS3 doesn´t work with a saving daylight 
time and Java does. How can i get this problem solved?

What version of the product are you using? On what operating system?
Windows Server 2008 and TomCat 6 
Adobe flex 3.5
Java 6
dpHibernate1.0.1.swc
dpHibernate1.0.17.jar 

Please provide any additional information below.

ps: sorry about my bad english!!!
