It's very possible that this is something I would and should know if I read up on ear-packaging, but if anyone has the courtesy to answer I'd be happy :) Why is it necessary to reference the jboss-seam.jar, el-api.jar and el-ri.jar in the application.xml of your seam ear application? (For comparison; working with Spring you don't have to do this - just include the spring.jar in the root of your ear).
