Make sure the romdata.xml file is in a folder called ~/rombrowser. If you're in a Windows environment, you will have to figure out yourself where to put it, but I look up user.dir to find the romdata files.
But otherwise, run java -cp rombrowser.jar. The first thing you get is a filechooser panel, use that to select the folder in which you store your roms. It will recurse into subfolders, but make sure there's no circularity there or else you'll be in trouble.
Also, this will only run in Java 1.2 or greater, I believe, so MacOS 9 folks are out of luck.
