UriInfo always null when using @Context

[slowdive]

I did a little bit of searching about this issue, and most places seem to mention RESTEasy. Since this application I am working on needs to be deployable to both Weblogic and JBoss, I am hoping to be able to use java/javax libraries. This is my code:

@Context

protected UriInfo uriInfo;

@Context

protected HttpHeaders headers;

The headers variable is not null, but uriInfo is... Also, this gets populated correctly when deploying to Weblogic. I am using JBoss AS 7.1.1Final and my deployment is an EAR containing a RAR and 3 WARs.

Is the @Context UriInfo available if used as a method parameter?

Thanks a bunch! Making it a method parameter solved the problem. Strange that it wouldn't work as a member variable though.

Don't know. 5.2.2 of the spec says

An instance of UriInfo can be injected into a class field or method parameter using the @Context annotation

Tried a simple

@Path("/status")
public class Status
{
    @Context
    UriInfo info;

and put a breakpoint in one my called methods and I did manage to get a non-null instance on 7.1.1 so it's not a direct bug, I think

Well, I thought this was resolved, but now I am seeing inconsistent results. In summary

• We are using the CXF JAX-RS implementation
• If I use the context annotation for a member variable, it is always null
• If I use it as a method parameter, sometimes it is null, and sometimes it is not. I could not determine a clear pattern for what is causing it to be one way or another.
• Either way works fine in Weblogic
