Sean, The way I do it (and this may not be the best way) is to use RPC to send the user requests to the server. Then, I store the request data in a table on the server, generating a unique id for that data. The unique id is returned to the user via the RPC callback. Then, a new window is opened with the url set to the servlet address and the unique id as the token in the url. In the servlet, I use that token to look up the request data, build the PDF, delete the request data, and return the PDF. This method allows me to send as much data as I want via RPC and then I only need to send a single parameter with the url to the servlet.
