As part of porting a legacy application to GWT, we need to embed our existing JSPs inside of our GWT app. Many of these pages are quite long, resulting in a double scrollbar- one for window of the main app, and a second one for the content of the frame. I'd like to get rid of the internal scrollbar, and just have the normal browser scr...

What options for async io (socket-based) are there in java other then java.nio? Also does java.nio use threads in the backround (as I think .NET's async-socket-library does, maybe it's been changed) or is it "true" async io using a proper select call? ...
I have created java api -ported from C# to be more specific- which aside from public interface, contains a lot of internal stuff that I don't want a user to know about. In C#, I have used doxygen to generate documentation. I presume javadoc has similar features to exclude certain public members, classes, even packages. Would someone s...
