[forge-dev] Class Loading Error: ResourceLoadingException

[Lincoln Baxter, III]

Darn, for some reason this got saved as a draft and never sent... sorry.

There is already a seam-render module in Forge, and the duplicated
classloader resources is something that Weld should be able to understand
because classes from different classloaders are different classes.

This appears to be a bug in weld.

What happens when you add a module dependency on: "org.jboss.seam.render" ?
If it works, I can fix this as a workaround in forge for now, but it's not
the right solution in the long run, and we'll have to get weld fixed up.
I'm working on creating a custom WeldBootstrap application that adds each
plugin as a deployablearchive, but that's going to take some time unless I
can get help from the weld guys.

Pete, Ales, Josef - any tips on how to get this to work?
