Single-sourcing with E4 apps? [message #874062]

Does RAP support E4 applications based on the programming model where you use E4's provided E4Application class instead of setting up your own Display and workbench? It seems hard to move the initializations done in the E4Application class into an EntryPoint in the way people seem to do that with 3.x-apps...

Besides, from reading bugzilla I gather that there might already be an entry point, or at least ApplicationConfiguration, registered for the E4 app? I am led to believe that's the case because I get the following exception when I try to register my own ApplicationConfiguration with EntryPoint "org.osgi.service.http.NamespaceException: The alias '/rwt-resources' is already in use."

If the E4 app already registers an entry point, how can I launch the RAP app based on that entry point? If I just do Run without specifying anything, I get an error saying that entry point /default does not exist...

Search this forum - RAP does not yet support e4 and if you'd get it up
and running you'll notice that there are blocking problems in a
multi-user env (in this case the IEventBroker!)

Thanks! Sounds like the question is a good candidate to answer in the FAQ as well Smile

We have plans to look into RAP on Eclipse 4, maybe for RAP 2.0, but no
promises yet.

Regards, Ralf
