Using a developer build:

Download and install WebLogic Server 9.2.  

In IDE, select Add Server to register the server.  Fill in location and instance properties (examples server,
weblogic/weblogic).  After clicking Finish, the following error appears:

An entry for BEA Weblogic Server appears under the Servers node, so the registration may or may not have worked.
