Adapter for Enterprise Javabeans throws an AdapterServiceException for any error that occurs:

The first two situations indicate some fundamental problem that prevents the adapter from being started or terminated. These are administrative errors that do not typically involve client services using the adapter to access EJBs.

The third situation indicates a runtime error that occurs when the Java service pub.ejbadapter.removeEJB attempts to invoke a remote EJB's remove method. In this case, the client service may be involved and will likely need to trap the error.
