Two DSL in same project [message #1775937]

Hi, I have a DSL "A" with entities and some others functionalities to generate Java services backend contracts. Now I would like to create a new DSL "B" in the same project (in the same Eclipse plug-in for the existing DSL "A"), in order to read these entities defined in DSL "A" to generate JPA code for these entities and others artifacts. It this possible? What are the steps to do this?

Thank you very much in advance.

simply having two language sections in the workflow should do the trick

Hi, Thanks for your answered.
I decided to create a new xText project for the new DSL "B", called "EDL", that must reference elements in existing DSL "A". I followed your Blog's post "Xtext: Referencing Elements of one DSL from another DSL". But I getting an error when I run GenerateEDL.mwe2 (the error happens only if I reference the DSL "A"). Can you give me some help? I already searched on Google without success.
In the Error.zip file I put the main files to inspect the problem.

Thank you very much for the help.

Hi

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.emf.ecore.xmi.IllegalValueException: Value 'org.eclipse.emf.ecore.impl.DynamicEObjectImpl@326f3ab4 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@2264ea32 (name: EReference) (instanceClassName: null) (abstract: false, interface: false))' is not legal. (platform:/resource/br.com.senior.edl/model/generated/EDL.genmodel, 10, 129)

strongly suggests a problem with the br.com.senior.edl registration

3230 [main] INFO clipse.emf.mwe.utils.GenModelHelper - Registered GenModel 'br.com.senior.sdl.model' from 'file:///C:/mk/git/sdl/br.com.senior.sdl.model/model/sdl.xcore'

is inconsistent. "file:///" is unusual. I would need to read the specification to see what it really means. But I suspect it is at least one of your problems.

Regards

Ed Willink

Yes, I agree with you, I think the correct way is to use:

referencedResource = "platform:/resource/br.com.senior.sdl.model/model/sdl.xcore"

but then I get the error: java.lang.RuntimeException: Problems running workflow br.com.senior.edl.GenerateEDL: java.io.IOException: The path '/br.com.senior.sdl.model/model/sdl.xcore' is unmapped
It only works if I install the DSL plug-in "A" in my Eclipse.
