OCL in RAP (eInvoke not implemented) [message #797806]

Hello

We are using EMF together with RAP and therefore an ecore metamodel. Additionally, some method bodies are defined with OCL. If we call a method of this plugin whose method body is defined with OCL, we get a
java.lang.UnsupportedOperationException: eInvoke not implemented for getAllConnections at org.eclipse.emf.ecore.util.BasicInvocationDelegate.dynamicInvoke(BasicInvocationDelegate.java:96) ...

For that case, we tried to implement a fix recommended by ttp://wiki.eclipse.org/MDT/OCLinEcore#Standalone. Therefore we added OCL to our target platform and added org.eclipse.org.ecore as a dependency in our manifest.mf. However, we encounter an HTTP ERROR 500 now when running our project
( Problem accessing /rap. Reason: Entry point does not exist: de.uni_mannheim.informatik.swt.models.plm.editor.PLMEditorAdvisorApplication
Caused by:
java.lang.IllegalArgumentException: Entry point does not exist: de.uni_mannheim.informatik.swt.models.plm.editor.PLMEditorAdvisorApplication ...)
We highly appreciate any help,
Nico

Hi Nico,

Do you provide your application entrypoint using IEntrypoint or
IApplication?

The procudure to track down those errors is always the same: enter the
command `ss` in the OSGi console (you have to start with -console
parameter) and make sure the bundle that provides your entrypoint is
present and active. If it's not, try to start it. Mostly it's just a
matter of missing bundles.

HTH, Ralf

Thanks Ralf, we found the missing bundle with the "Validate Bundles" button in the "Bundles" tab in the run configurations and activated it. Works perfectly now.
