One of the nice things about GF is that it can precompile the JSPs on deploy, but you can still make JSP changes in place. I just wish we could easily compile JSPs in advance as well, but that's a different issue.

But some would argue that this step need not be done at all, at least at this stage of development. So, that could shave precious seconds from the turnaround.

This is fixed in NetBeans 6.

Specifically, it would be nice if rather than restarting the entire EAR application when an embedded WAR changes, just restart the affected WAR. Basically, be more considerate about the level of the change and its affect on the restart. If I have a WAR in an EAR with 2 other WARs, and a bunch of EJBs, it would be nice to not have to reload the whole kit for a change in one component. Obviously, if you change something at the root, then you need to reload.
