server side proxy in java

Anybody, How to create Server side proxy using Java. I want to create server side proxy because of cross domain issue.
Any useful links, tutorials...

Thanks in advance.

I created one for the web services chapter of Ajax in Practice. You could grab the example code and inspect it if you like. I essentially just leverage the HttpClient project.

I just downloaded the example but it gives the error....which I do not want to seee

Security Error: Content at file:///C:/Documents%20and%20Settings/rb/Desktop/aip.sources/chapter1and2/chap1and2/index.html may not load data from file:///C:/Documents%20and%20Settings/rb/Desktop/aip.sources/chapter1and2/axis/HelloWorld.jws.

Those are not the examples I spoke of. I believe that the chapter # is 10.

You probably didn't mean this to be rude, but it was.
