I don't consider myself an advanced user, so advanced users aren't going to find many pearls of wisdom cast before them.
What you will find here, just like the rest of the site, is a collection of the sort of information I would have liked myself when I was starting with GWT, Java and Eclipse.
None of it is new, all of it is available elsewhere (or how else would I have found it).
Entries are arranged in order of how basic and/or essential I consider them.
If you know of something you think should be here that isn't, then please contact me and unless you ask me not to, I'll make sure your name gets mentioned
