As long as the container (WebLogic, etc) supports it and it was launched
via Eclipse, it should "just work." For example, I frequently debug my
Jetty-based app in Eclipse and see immediate results as I change code.
Of course some types of code changes can not be dynamically pushed out
without a restart or re-deployment; things like removing methods or
fields of a class. In those cases, Eclipse informs me and asks what to do.
I think if you are able to launch WebLogic from Eclipse and you have
your Eclipse project set up to build classes into the WEB-INF directory
of your deployed app, then it will work.
Hope this helps,
Eric
