Want to use Forms in RAPe4 Incubator [message #1690492]

Hi,

I want to use the RAP or RCP Forms in my RAPe4 application, because I migrate an Eclipse RCP 4 Application to Eclipse RAPe4 and in this application are the Forms used.

I have tried to use the Eclipse RAP Forms, but if I do this, there came two mistakes:

java.lang.RuntimeException: org.osgi.service.http.NamespaceException: The alias '/rwt-resources' is already in use.

org.eclipse.e4.core.di.InjectionException: java.lang.NoClassDefFoundError: org/springframework/core/io/Resource

I think this is because org.eclipse.e4.ui.workbench and org.eclipse.rap.ui.workbench, are used in this application.

Does anyone know a solution to use Forms in RAPe4?

Thank you
André

Hi,
1) First error: "java.lang.RuntimeException:
org.osgi.service.http.NamespaceException: The alias '/rwt-resources' is
already in use."
Probably you are right - this is because both
org.eclipse.e4.ui.workbench and org.eclipse.rap.ui.workbench exists. You
should remove the "org.eclipse.rap.ui.workbench".
2) Second error: "org.eclipse.e4.core.di.InjectionException:
java.lang.NoClassDefFoundError: org/springframework/core/io/Resource"
Missing spring framework?! Who is using it?

There is no ready solution for using forms bundle
(org.eclipse.rap.ui.forms) in e4. Probably, you have to modify it a
little - see [1].
Also remove the dependency to"org.eclipse.rap.ui" and add
"org.eclipse.rap.rwt". Some other changes may need.
