Folks have mentioned Eclipse as an IDE, but there's also Eclipse as a platform. I have three Eclipse RCP apps I use for visualization daily. I also manage a lot of equipment that requires java webstart to load a configuration GUI to accomplish tasks that would be darn near impossible at a CLI or any other way. I logged into Cisco TAC the other day. Requires Java for ticket management tasks. I use some rf propagation tools for a hobby that are java apps. I make frequent use of Deskzilla.
