Hello ! I made a simple seam project with Jboss Tools into eclipse IDE. I trie then to use a simple external library just to test. When the code of the external library is executed I habe this error : | 08:03:54,284 FATAL [application] java.lang.reflect.InvocationTargetException | javax.faces.el.EvaluationException: java.lang.reflect.InvocationTargetException | at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:91) | And much more Exceptions... Why can't I use the code of my library ? Hope you can help me ! Thank you Joel View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4135830#...
