To see discussions on Java and the resources NI has to offer, I highly recommend using the advanced search page. Goto www.ni.com >> support >> advanced search (it is at the bottom--click on the words). This lauches the a new web page which allows the user to search the resources of interest. In your case, enter java labview in the all the words field and search everything. There are several good hits.
