I have been working with WebLogic Server since 1999 when it was still a BEA Systems product. Though professionally I would characterize myself as an architect/developer, I have been working with WebLogic administrators for more than a decade. In fact, at BEA Systems I was the author of the original BEA WebLogic Administrator Certification exam. As a WebLogic consultant, the primary tools that I use with clients are the WebLogic Scripting Tool (WLST) and the WebLogic Diagnostic Framework (WLDF).
WLST is based on Jython, the all-Java version of Python. Since Jython runs in the JVM it is possible to invoke WLST commands directly form Java code. The possibilities are endless, you could use a Swing Gui front end and a WLST back end to provide automated management and monitoring for WebLogic.
