most java2exe tools require that the one who wants to run the exe has java installed. Most tools cause more problems than they solve. So I see no need to use one and trying to do so is imho a bad idea.
We use url=http://www.ej-technologies.com/products/install4j/overview.htmlinstall4j[/url] to create executables from Java. Install4j has worked very well for us and so I recommend it to you but you should know that it is commercial software. I just did a quick google search for free software and found url=http://jsmooth.sourceforge.net/features.phpJSmooth[/url] but I really don’'t know how it works.
