Don't know the first thing about web stuff. Unfortunately I need to test a modified jar file which is part of a program that relies on Webstart. The jnlp files are downloaded from clicking on a button on the website and it supposedly downloads all the relevant jar files and resources. The client sends the information back to the server (Ubuntu) which uses a cgi file to handle the request

I'm running Windows Xp and Win7. Where would I look to easily set up a virtual environment so I could test the program on my computer without the hassle of setting up an additional physical server or actually running everything over the net?

Thanks
