I get the following exception while starting an application server in WebSphere ND 6.1.0.9<br />
<br />
javax.management.MBeanException: Exception thrown in RequiredModelMBean while trying to invoke operation setRPAAttribute<br />
<br />
and this exception causes a InvocationTargetException in SOAPConnector:<br />
