emf-rest's Issues

NullPointerException when generating code

Hello,

first of all thanks for the effort you put into emf-rest. It could be very helpful for us. We want to create web front-ends for our legacy applications whose configuration data is modeled with EMF.

So I followed the instructions at http://emf-rest.com/install.html to get the sample running on my machine:

Downloaded the J2EE Eclipse Kepler distribution (eclipse-jee-kepler-R-win32-x86_64)
Installed the emf-rest plugins from your update site
Created a new Dynamic Web Project
created a folder called "model" and put your example model (downloaded from http://emf-rest.com/Example.ecore) into the folder

When I now do a right click on Example.ecore / EMF-REST / Generate All + Copy Libraries nothing happens.

In the Eclipse console log I get the following output:

!ENTRY org.eclipse.ui 4 0 2013-10-21 10:11:11.078

Example won't build..

I get unresolved dependencies for com.mtcflow.engine.* with the Demo project.

http://emf-rest.com/ does not resolve.

It's the first link in the README - should it be https://som-research.uoc.edu/tools/emf-rest/?

Nullpointer Exception while trying Example

Hi,

I'm currently trying to get the example project running, but it's already throwing exceptions at the generation step.
I followed http://emf-rest.com/install.html and created a new simple maven project through eclipse. Copied over the Example.ecore into the src/main/resources folder and also copied over the Simpsons.xmi into the same folder.
I installed the newest version from your update site:
EMF-REST 2.0.3.201503272048 com.rest.emf.feature.group EMF-REST
After that I started the generation through the context menu on the Example.ecore.
You can see in the console output that there is a NullpointerException.

Apart from the obvious problem while generating, I noticed that while using my real emf model the corresponding genmodel that i copied next to the ecore file is being changed when the generation starts. Don't you use the existant genmodel if it is present already? Why is my original genmodel changed?

Regards,
Steffen

Documentation outdated

The link to JBoss EAP on the following page seems outdated.

https://som-research.uoc.edu/tools/emf-rest/install.html

Live demo is down

The live demo is not working: http://emf-rest.com/demo.html

Apparently, it is the code generation for the Javascript client that is getting stuck and eventually timing out:

http://emf-rest.com:8080/Demo/scripts/api.js

Updatesite offline

The docs state that the Updatesite for emf-rest can be found at http://emf-rest.com/update/v2/site.xml

This URL, however, redirects directly to the homepage, so no updatesite is found.
Is there any updatesite available? Can you update the docs?

Feature request: swagger docs

Hello

It would be a nice feature if emf-rest also generated swagger documentation for the rest api.

org.eclipse.e4.core.di.InjectionException: java.lang.NullPointerException

Hi , I just installed your plugin , and have some problems with it:
after setup as described http://emf-rest.com/install.html (clean eclipse and only emf-rest plugin)
right click on model shows menu EMF-REST and Generate All I see exception in Error Log as below
any special confgiguration is required or I missed something?

Java classes not generated completely

Hi,

You have done a very good job here just keep it up. Hovewer, I have a problem with the generation process. Environment is Eclipse 4.3, and EMF-REST 1.0.3.201409031707. The following steps have been followed:

There is only Generate All menu option and it generates almost everything except classes from meta-model elements.
Classes (e.g. Family.java, Cat.java etc.) can be generated through the genmodel file. After the first step all of these classes and Impl classes were empty.

However, after following these steps REST services couldn't be reached. After downloading the official example, we have narrowed the problem to the Example.impl package. To be more precise, in the generation process XML annotations are not generated (e.g. @XmlRootElement). After adding these annotations manually everything worked.

Compile errors in generated Java code

The code generate from our ecore model contains compile errors in the webmapi.service.IdentificationResolver class.

I was able to fix this compile errors manually and get the REST api running. However, I would expect that the generated code contains no compile errors.

This zip file https://www.dropbox.com/s/flpavdwepdb9z8m/IdentificationResolver.zip contains two versions of the IdentificationResolver class. One version that the code generation produces and one version that I manually adjusted. When you make a diff of the two versions you can easily see the issues. The password for the zip file is "emf2rest".

Reinhold

Do you have a clue what causes this problem? It occurs when I execute "Generate All + Copy Libaries" or "Generate EMF Model" or "Generate Serializers".. on our .ecore file.

Btw. when do you expect to have a version of EMF-Rest that supports POST http calls?
