After reading the whitepapers, I really like the look of the Zimbra Ajax toolkit. But I was dismayed to find Java Server Page code scattered throughout even the Ajax parts of the of the zcs codebase.

If I'm not planning on using JSP in my server, should I just walk away from Zimbra and use Dojo or something else, or is there some possibility that the Zimbra Ajax code could be decoupled from JSP?
