AJAX list selections

Create two jsp pages: 1) Should have two lists of items side by side, allowing the user to drag items between them. When the user is done, they click OK. The lists should be obtainable from a simple Java class. 2) Should be the target of the first page, and should list the items in each of the two lists. It should also be able to pass these to the server. Ideally, the prototype/[login to view URL] libraries should be used.
