actually I think jeff was a tad bit to fast on the draw. browser based is a tad differend, then app.
Hmm fair enough but as someone else pointed out, "browser based" is really incomplete.
If you want to build a Java App, then cokeandcode is a regat place to start,
If you want to build a J2EE based game, then probably the J2EE oriented forusm here on java.net woukld be a good place, unelss someone else has a pointer to good starting J2EE stuff.
If you want to build an Applet, well I stil lthink cokeandcode is a good introduction but be aware that ,many triks done in Apps can't be done in Applets and there are ugly but doable work-arounds.
