By the way I re-post the error I get with this code. The one I've posted is was not matching. Caused by: java.lang.VerifyError: (class: Accessor$com/bnpparibas/eqd/fish/fwk/introspection/SampleBean_directAccessField, method: setValue signature: (Ljava/lang/Object;)V) Bad type in putfield/putstatic | at java.lang.Class.getDeclaredConstructors0(Native Method) | at java.lang.Class.privateGetDeclaredConstructors(Class.java:2357) | at java.lang.Class.getConstructor0(Class.java:2671) | at java.lang.Class.newInstance0(Class.java:321) | at java.lang.Class.newInstance(Class.java:303) (out of topic) his there an edit post tool ? I've looked for one, but I did not see any. Thanks. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4223019#...
