Egl and epsilon standalones [message #1063938]

Sun, 16 June 2013 07:03

Eclipse User

Hello,

I modified the org.eclipse.epsilon.examples.standalone / org.eclipse.epsilon.examples.standalone.egl from the repository to use UML instead of Emf models as I need, also changed the imports from emf to uml ones but for some reason I think it keeps using emf instead of uml because when I run it I keep getting this error below. Also, minimal attached.

PS: Sorry for all the posts but it's driving me mad, I didn't think this was so hard to make it work.

Hi Patricia,

I'm afraid that the attached archive only contains the compiled version of your code (.class files). Could you please try to export your project using File->Export->General->Archive File instead?

Cheers,
Dimitris

Hi Patricia,

To get rid of this exception I had to do the following:

1) In model.uml, change http://www.eclipse.org/uml2/3.0.0/UML to http://www.eclipse.org/uml2/4.0.0/UML using a text editor

2) Replace the following line

UMLResource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);

with

EPackage.Registry.INSTANCE.put(UMLPackage.eINSTANCE.getNsURI(), UMLPackage.eINSTANCE);

3) Uncomment the following line: properties.put(UmlModel.PROPERTY_METAMODEL_URI, metamodel);

It still doesn't work but that's due to unrelated errors in subsequent EGL statements (e.g. Package.add should probably be Package.all instead).

Cheers,
Dimitris

Hi,

Sorry to disturb again... I exported it as runnable jar but when I execute it I get the following error.

Quote:

Exception in thread "main" java.lang.IllegalArgumentException: URI is not hierarchical
at java.io.File.<init>(File.java:363)
at EpsilonStandalone.getFile(EpsilonStandalone.java:85)
at EpsilonStandalone.execute(EpsilonStandalone.java:32)
at EglStandalone.main(EglStandalone.java:15)

Does that mean I have to change the URI lines from the standalone example to make it work? If so, what do I need to put instead?

Thanks in advance.
Cheers.

Hi Patricia,

No worries. The discussion in the following bug report may help.

Hi Dimitris,

Thanks to your link and some more info I was able to make it work.

Talking about this example:

- When I run the EglStandaloneExample.java as a java application it works as expected.
- However, when I right click the plug-in project and run it as an Eclipse Application, I manage to make it work through the "Generate" menu I added (the window to choose the uml model at least appears) but then I suddenly start getting exceptions which looks like this one (the part that changes from an exception to the other is the url):

Quote:

!MESSAGE Exception encountered whilst trying to retrieve EPackage for nsUri: http:///org/eclipse/datatools/modelbase/dbdefinition/dbdefinition.ecore
!STACK 0
java.lang.OutOfMemoryError: PermGen space
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632)

...

Also this one:
Quote:

!MESSAGE Unhandled event loop exception
!STACK 0
org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.OutOfMemoryError: PermGen space)

I tried increasing the -XX:MaxPermSize up to 512m, but the exceptions keep happening. Any help on this? Tried writing a post in the PDE section but noone's answered it.

Thanks again.
PS: Minimal and uml model attached if needed.

Hi Patricia,

Unfortunately, I'm not able to reproduce this in my setup (MacOS) as I'm getting an SWT exception. I've had a quick look at your code and it appears that you're using Swing for the UI part. SWT and Swing don't mix very well so I'd suggest considering to implement your generator launcher as a context menu action. See the "Register EPackages" action in [1] for an example of how to do this.

Cheers,
Dimitris

Hi Dimitris,

Maybe you forgot to add the [1] source info?
