BEA Systems Inc.'s WebLogic Workshop is a combination development/run-time environment, very much in the spirit of IBM Corp.'s WebSphere Application Developer.

Whereas J2EE was all about abstracting low-level entities such as database rows and message queues, WebLogic Workshop is all about abstracting J2EE.
