Hessian service on the server returns a list of Nodes. The Node class is
implemented exactly on the client side. When I make the remote call, the
function returns a list of HashMap instead of a list of Nodes. It is wierd
though there is no exception when the output is cast to ArrayList<Node> but the
problem arises when I try to iterate through the list, then I get class cast
exception.
What steps will reproduce the problem?
1. On the server side create a function that will return a list
(ArrayList<Node>) of some object, say Node
2. On the client side do the remote call and try to access the ArrayList content
3. You get class cast exception
What is the expected output? What do you see instead?
We should see no exception, a runtime exception is thrown root cause being the
class cast exception.

JavaSerializer is the default serializer for custom classes. instead of
creating new serializer instances
for every class, the serializers could be rewritten to be thread-safe
singletons.

Hello
ActivityManager gives a warning:
"Launch timeout has expired, giving up wake lock!" after call 1
Later a exception :
"Caused by: com.caucho.hessian.client.HessianConnectionException: -1: "
is thrown
...
proxyFactory.setHessian2Reply(false);
api = (BasicAPI) proxyFactory.create(BasicAPI.class, webServiceUrl,
getClassLoader());
System.out.println(api.saySomething()); // call 1
System.out.println(api.saySomething()); // call 2
...
saySomething() returns a random number from the server
call 1 works fine and returns a random number as expected
call 2 was expected to do the same but hangs for a few seconds and throws
the exception mentioned above
i am running the above code in eclipse with android plugin
How should i reuse the same interface(api from code above), so that i can
recall the web service a few more time.
Since now it is only working only once during a execution.
Note: the string returned for the call 2 is seen in the LogCat though
mangled as "r�À�SÀ��Random String 14351 From serverz"
which was expected as "Random String 14351 From server" in System Out.
i appreciate your any help in this issue.
thank you and regards

There exists a method
com.caucho.hessian.client.HessianProxyFactory.setReadTimeout(long
timeout) which allows one to set the socket timeout on requests in
milliseconds. This is ultimately used to call
java.net.URLConnection.setReadTimeout(int) in
com.caucho.hessian.client.HessianProxyFactory.openConnection(java.net.URL).
There is also a corresponding
com.caucho.hessian.client.HessianProxyFactory.getReadTimeout().
If you look at the android docs for java.net.URLConnection, in
addition to set/get methods for the read timeout:
http://developer.android.com/reference/java/net/URLConnection.html#setReadTimeout(int)
http://developer.android.com/reference/java/net/URLConnection.html#getReadTimeout()
There are set/get methods for the connect timeout:
http://developer.android.com/reference/java/net/URLConnection.html#setConnectTimeout(int)
http://developer.android.com/reference/java/net/URLConnection.html#getConnectTimeout()
If you look at the javadoc for the current version (4.0.7) of the
server side Java implementation of Hessian, all 4 of these methods are
supported:
http://www.caucho.com/resin-4.0-javadoc/com/caucho/hessian/client/HessianProxyFactory.html#setReadTimeout(long)
http://www.caucho.com/resin-4.0-javadoc/com/caucho/hessian/client/HessianProxyFactory.html#getReadTimeout()
http://www.caucho.com/resin-4.0-javadoc/com/caucho/hessian/client/HessianProxyFactory.html#setConnectTimeout(long)
http://www.caucho.com/resin-4.0-javadoc/com/caucho/hessian/client/HessianProxyFactory.html#getConnectTimeout()
This appears to be present in hessian 4.0.3:
http://caucho.com/download/hessian-4.0.3-src.jar
but not in hessian 4.0.1:
http://caucho.com/download/hessian-4.0.1-src.jar
(There does not appear to exist a hessian 4.0.2, at least not at
http://hessian.caucho.com/#Java)
But hessdroid (as of rev 29:a1c0504b5811) only supports the read
timeout, and not the connect timeout.
My suggestion is to add support for the connect timeout. A patch is
attached.

The scenario is:
If the server is down, for example. The client app wants to connect to the
server to get data.
Hopefully, the client side should know exceptions happen. However, the app gets
stuck. No response at all.
Any ideas???
Many thanks.

on 18 Jun 2012 at 6:30
What steps will reproduce the problem?
1. We are using hessdroid library for android client.
2. When the server sends an object of java.util.Locale then hessdroid
library throws the following exception:
com.caucho.hessian.io.HessianFieldException:
com.<custom data type having locale as field>.locale:
com.caucho.hessian.io.LocaleHandle
(com.caucho.hessian.io.LocaleHandle@437aaa60) cannot be assigned to
'java.util.Locale'
3. While debugging we found inside method
com.caucho.hessian.io.JavaDeserializer.ObjectFieldDeserializer.deserialize()
that the statement
field.set(obj, value);
throws the exception while setting the Locale field type.
4. We tried to fix this. We changed the access modifier of
com.caucho.hessian.io.LocaleHandle.readResolve() method from private to
public. This resolved the problem.
What is the expected output? What do you see instead?
The Locale object should be properly resolved.
What version of the product are you using? On what operating system?
Checked out source code on April 8, 2010. We are working on Windows XP SP3.
Please provide any additional information below.
Could you please confirm if the fix is appropriate and when can we expect
the new library release?
Thanks

If I call a method on the client that does not expect on the server, I
think it is perfectly reasonble for that to throw some kind of
exception. But I think it ought to be a clear exception that one
would expect to catch.
Here's what happens with rev 29:a1c0504b5811 if I call a method
(updatePushNotificationInfo) that does not exist on the server:
java.lang.reflect.UndeclaredThrowableException
at $Proxy0.updatePushNotificationInfo(Native Method)
... 3 more
Caused by: com.caucho.hessian.io.HessianServiceException: The service has no method named: updatePushNotificationInfo
at com.caucho.hessian.io.Hessian2Input.prepareFault(Unknown Source)
at com.caucho.hessian.io.Hessian2Input.startReply(Unknown Source)
at com.caucho.hessian.client.HessianProxy.invoke(Unknown Source)
at $Proxy0.updatePushNotificationInfo(Native Method)
... 3 more
I would think that a HessianServiceException would be a reasonable
thing to throw. I'm not entirely sure why (I'm not the familiar with
reflection), but as far as I can tell, I always get a
java.lang.reflect.UndeclaredThrowableException if I throw any kind of
declared exception. This is despite the fact that
HessianProxy.invoke() declares that it throws Throwable, and almost
every call to invoke() that I can find within the hessdroid library
declares that it throws IOException, except for the call in
JavaDeserializer.resolve() that declares that it throws Exception.
So it appears to me that my only recourse is to throw an undeclared
exception. See the attached patch. In HessianProxy.invoke() I'm
catching the HessianServiceException and re-throwing it as a
HessianRuntimeException. With this, I can now detect this situation
cleanly in my code by catching HessianRuntimeException, which seems to
me to be far better than UndeclaredThrowableException:
com.caucho.hessian.client.HessianRuntimeException: com.caucho.hessian.io.HessianServiceException: The service has no method named: updatePushNotificationInfo
at com.caucho.hessian.client.HessianProxy.invoke(Unknown Source)
at $Proxy0.updatePushNotificationInfo(Native Method)
... 3 more
Caused by: com.caucho.hessian.io.HessianServiceException: The service has no method named: updatePushNotificationInfo

at com.caucho.hessian.client.HessianProxy.invoke(Unknown Source)
at $Proxy0.updatePushNotificationInfo(Native Method)
... 3 more
Any thoughts? Is there any way to throw a non-RuntimeException in
this case? Are there any other unintended consequences of doing this
(like other cases for HessianServiceException where this might not be
appropriate?)
This is compiled on OSX 10.6.8 and running on Android 2.3.5, but I
doubt any of that matters.
