Maybe this is a JBossWS-CXF's bug. JBossWS-CXF wraps all Exception in a RuntimeException and throws it. CXF is catching it, but it can't do nothing. I fixed this problem by modified jbossws-cxf-3.0.3.GA/modules/server/src/main/java/org/jboss/wsf/stack/cxf/AbstractInvoker.java like that. See below. protected void handleException(Exception ex, Exchange exchange, Method m) | { | Throwable th = ex; | if (ex instanceof InvocationTargetException) { | th = ((InvocationTargetException)ex).getTargetException(); | if (th != null) { | for (Class<?> cl : m.getExceptionTypes()) { | if (cl.isInstance(th)) { | exchange.getInMessage().put(FaultMode.class, | FaultMode.CHECKED_APPLICATION_FAULT); | throw new Fault(th); | } | } | if (th instanceof Fault) { | exchange.getInMessage().put(FaultMode.class, | FaultMode.CHECKED_APPLICATION_FAULT); | throw (Fault)th; | } | } | } | | exchange.getInMessage().put(FaultMode.class, FaultMode.UNCHECKED_APPLICATION_FAULT); | if (th instanceof Fault) | throw (Fault)th; | | throw new Fault(th); | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4183223#...
