adapter_config and Java error

I have just completed the installation of a webMethods Integration server. All tools / monitors / etc. appear to work fine - except the adapter_config tool. When starting the tool I get the following error:

Exception in thread “main” java.lang.NoClassDefFoundError:
COM/activesw/visual/event/EditListener

Any ideas ???

Cheers,
