I tried creating a sample project in netbeans using the Seamgenerator with no manual configuration change. These are the steps i followed 1. I downloaded and added the JBOSS 4.2.1 GA to Netbeans as a server 2. I created a Enterprise Skeleton app using the netbeans Seamgenerator plugin 3. I used all default configurations for generating the Enterprise APP Here is the first problem i faced. The Output window always comes up with the following statement cvc-complex-type.2.4.b: The content of element 'web-module' is not complete. One of '{"http://www.netbeans.org/ns/freeform-project-web/1":web-inf}' is expected. This points to an XML tag below <web-module> <doc-root>view</doc-root> <context-path/> <j2ee-spec-level>1.5</j2ee-spec-level> </web-module> However i ignored this problem and went ahead deploying the app. 4. I built and deployed the app in Default> Deploy directory 5. Started the JBOSS server 6. JBOSS server failed with multiple errors I am outlining the type of errors as below java.lang.RuntimeException: java.lang.NoSuchMethodException: com.sun.faces.application.ApplicationImpl.addELResolver(javax.el.ELResolver) This error is because it is picking the 1.1 RI implementation from somewhere. I am not being able to detect it. However i am stuck and i think anybody/ everybody using netbeans M10 - JBOSS 4.2.1 and SEAM may have the same problem as mentioned above. Help needed.
