java.lang.LinkageError using a module for common jars in multiple applications

icordoba Oct 26, 2013 6:38 PM

Hello,

I have multiple war applications deployed in my JBoss 7.1: Most of them use same jars, which so far I've placed in WEB-INF/lib dir.

I've learnt about JBoss modules, so I've decided to give it a try and put common jars (PrimeFaces, ...) in a module (in modules dir... my module/main/...

My problem is that even adding the dependency content in module.xml, module jars depending, for example, in JEE classes, will return a java.lang.LinkageError + ClassNotFound exception.

I've read all docs available on modules and class loading, also tried including the dependencies in MANIFEST.MF in the war file but no difference. Thanks for any ideas

(Stacktrace)

In module's module.xml file, I'm doing:

</dependencies>

but still get:
