Hi, maybe that's a clue to locate the error, because the same error java.lang.RuntimeException: Interceptor class not found: org.jboss.seam.ejb.SeamInterceptor happens here after I do the following: Goto Preferences --> J2EE Module Dependencies of project "sample" uncheck JAR/Module "jboss-seam.jar" and "jbpm-3.1.1.jar" / Project "sample" Press OK and Redeploy After that all the rest fails (deploy ejb, deploy war). I guess eclipse is messing up settings that are pre-configured by seam-gen. When I go to the preferences again, the items above are checked again, magically.
