How do I add new JSP and HTML templates or edit the existing ones?
Well, I see you’re resourceful, and fast. 😉  If you’ll notice in the ‘doc’ directory in there, you’ll find the instructions for adding completely new templates in case you want to leave the default ones and just add your own.
FYI..How do I save these so they aren’t overwritten in future upgrades?
Unfortunately, at the moment you can’t so be sure to keep a backup.  We’ll be looking at making the mechanism more robust in the future.
Just to add, man what an awesome tool. Although I’ve been programming exclusively in Java for over 7 years now, I had a hell of a time breaking into the J2EE environment. I learn from books, and they were not helping me one iota. I got MyEclipse and three weeks later I’ve written everything from JSP’s to Servlet to Taglibs. Again, fantastic product.
Now feedback like this makes it all worthwhile. 🙂
