XBase in Eclipse Product / RCP application? [message #728946]

I am trying to run an Xbase editor in an Eclipse "product". This product does not contain all JDT stuff for now. When I use a Java type in the XBase editor I get the error message:

0    [Worker-3] ERROR org.eclipse.xtext.validation.CompositeEValidator  - Error executing EValidator
java.lang.RuntimeException: org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: java.net.MalformedURLException: unknown protocol: java

I think that there is a dependency from XBase to some plugin / feature. I have tried to add all JDT plugins, all emf and all Xtext plugins to the product's features, but the error remains. Does anyone know what the necessarily dependencies are for using Xbase this way, and what causes the "unknown protocol" error?

Jos,

It appears that
org.eclipse.xtext.common.types.access.impl.AbstractJvmTypeProvider.registerProtocol
should register a resource factory for the "java" protocol when I look
at how the Xcore editor functions.

Ed,

The org.eclipse.xtext.common.types plugin is installed in the running workspace, so I would expect it to register the resource factory. Any idea why it doesn't ?

Hmmm,

I did create a Project (general one) and put the Xbase file in there. If instead, I create a Java project and put the Xbase file in there it works ok. It uses some of the Java project settings.

Hi Jos,

Xbase uses the JDT to bind against Java types. If you want to use that
without the JDT installed, you'll have to customize a lot of services.

Sebastian

Sebastian,

Thanks for the clarification. I am using Xbase as an expression language in a business modeling tool. As you can imagine we have no Java projects there, just business models.

But I do see the point that you need access to java services, so my solution for now is to add a Java project in the background.
