[errai-dev] Problems I encountered while using Errai and JAX-RS

[Christian Sadilek]

Hi Daniel,

Yes, the javax.ws.rs.core.Response object is not GWT-translatable. We could try and workaround this by overriding the type (we already did this for various other but simpler EE classes). Nobody requested this yet but it might be worth doing. GWT's Response type is somewhat similar from a client's point of view and can be used in a callback (see https://docs.jboss.org/author/display/ERRAI/Handling+Responses)

The second problem seems to imply that the CDI Decorators have to be dependent-scoped. Did you see this conversation:
http://transcripts.jboss.org/channel/irc.freenode.org/%23weld-dev/2011/%23weld-dev.2011-10-17.log

Can you share more information about your beans? You can also post it to the errai or the weld forums, of course.

Cheers,
Christian

Unfortunately I get compiler errors telling me : "No source code is available for type javax.ws.rs.core.Response; did you forget to inherit a required module?". Any ideas about that?

BUT, as soon as I try to attach CDI decorators to such an Interface, Weld complains with:  "org.jboss.weld.exceptions.UnproxyableResolutionException: WELD-001306 Attempting to inject an unproxyable normal scoped bean Decorator….", although the implementation is perfectly proxyable. Did anybody experience something similar?
