I'm trying to split my utility classes away into their own jar file so I can easily reuse them from different seam projects and maintain a single source tree. I've created a jar containing the classes but I have not been able to add the jar into my ear (or war) correctly. I've tried a few different approaches with no success: - adding the jar to project.ear/project.war/WEB-INF/lib (class not found) - adding the jar to project.ear/ and adding a module tag inside application.xml (bean class has no local, webservice or remote interfaces defined) - adding the jar to project.ear and adding a loader-repository tag inside jboss-app.xml (expected only one loader-repository tag) Some of the classes inside my jar are seam components which is why I've posted this question in the seam forum. My project.ear is esentially a generic empty seam-gen project to which I've added my jar. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4025590#...
