hi. we decided to develop something using jboss as + jboss seam. since we're new to jboss as and seam we took one of the examples from seam (the dvd store) and trying to create our code by it. we have a few problems but the the one we just can't understand is this: we used ant to build the dvd-store example and it worked great on the jboss as and now, out of the blue it stoped working! we have no idea why because we dont remember changing anything in the jboss as or the example itself... when we run the jboss as we get this exception: anonymous wrote : DEBUG [org.jboss.mx.modelmbean.ModelMBeanInvoker] Failed to invoke ctor(MBeanInvoker) for: class org.jboss.jmx.connector.invoker.AuthenticationInterceptor | java.lang.NoSuchMethodException: org.jboss.jmx.connector.invoker.AuthenticationInterceptor.(org.jboss.mx.server.MBeanInvoker) any ideas of why this happens now even though it didnt use to heppen? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3985433#...
