javascript is for client-side only; JSP has serverside access. Personally, I use javascript for client; php for server; and forms or AJAX, as appropriate, to transmit the information for the query.

I can see passing parameters through javascript, but passing an entire query? That seems like a security issue waiting to happen. You sure you want to do that?
