http://www.mousetech.com/EJBWizard.html This isn't strictly speaking a deployment tool, but a RAD tool for creating the core code, deployment info, and prototype
JSP's for EJBs. It also can create an
ANT build.xml file for compiling/deploying. Everything's driven by templates, so it's easy to customize.
Unfortunately, I did a major overhaul to it and the WebLogic templates probably need more tweaking. Bug reports are very much appreciated!
It's free, BTW.
