[seam-dev] Loading resources from the ServletContext

[Pete Muir]

I noticed you committed a change that hard links the resource loader to the servlet context - we really need to avoid doing things like this - now we've tied every module that uses resources to running in Servlet! Seam 3 is no longer usable in Weld SE....

I designed the resource loading mechanism to be full extensible, and allow alternative sources of resources outside the classpath. So, what we can do inside the Servlet module, is provide a decorator for ResourceLoader that adds in the ability to load from the ServletContext. This way the need to duplicate all the logic for exposing the ServletContext via a producer is avoided to.

Stuart, can you back out the changes you made to Weld Extensions (excluding the getResources() changes), and add them into the servlet module from Seam as a decorator?

Thanks!

As this is before Weld has started, I can't just stick it in an application scoped bean or similar, and storing it in a static would require weld-extensions (and thus seam-xml, and any other modules that depend upon weld-extensions) to be included in the deployment, and not in the app servers lib directory. I don't think that this is really acceptable, however I can't think of any other way off the the top of my head.
