First of all, thanks for your help. I appreciate it. It is not in the actual code, it is being generated. It looks like the generated java is quite different in 4.0.4 and 4.2.2. In 4.2.2, it generates two additional methods, _jspInit() and _jspDestroy(). The problem is in the _jspInit() method, which is: public void _jspInit() { _el_expressionfactory = _jspxFactory.getJspApplicationContext(getServletConfig().getServletContext()).getExpressionFactory(); _jsp_annotationprocessor = (org.apache.AnnotationProcessor) getServletConfig().getServletContext().getAttribute(org.apache.AnnotationProcessor.class.getName()); } This is where the bad method call is. Do you think there might be a missing class, or some version conflict? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4165415#...
