InvocationTargetException on testing of Queue Manager

We are using webMethods IS4.6 and MQ Adapter2.1. Operating system is unix. We have upgraded from MQAdpater2.1 to 3.0. Also applied patches MQ Adapter service pack3.0. On testing the Queue Manager I have got the following error message

20031119 155950 java.lang.reflect.InvocationTargetException:isOn

at the error log.

Any help would be much appreciated.
