I've hot-deployed JSPs and classes with Tomcat 4.0.1, JRun 4.0, and WebLogic 6.1SP2.

I heard resin compiles even your servlets when it detects they have been modified. I would be interested in knowing about some way to redeploy some of my classes with restarting the webapp but i guess it has to do with how server's ClassLoader is designed and the Servlet spec has no restrictions for that.
