This error occurs when a resource adapter is still deploying.
So at line 78 of com.sun.enterprise.connectors.service.ConnectorAdminObjectAdminServiceImpl
"ActiveResourceAdapter ar = _registry.getActiveResourceAdapter(connectorName)"
ar is NULL and at line 84 (ar instanceof ActiveOutboundResourceAdapter) is false and throw new ConnectorRuntimeException("This adapter is not 1.5 compliant");
But this Exception is misleading (I lost a lot of time),it would be better to have something like "No Adapter Found".
