Subject Re: FOP Scalability
Date Fri, 10 May 2002 11:41:38 GMT
You could have additional servers (can be low-cost) and use JMS to post
jobs to a queue. These additional servers will listen on the queue
(automatic load-balancing through use of JMS), generate PDFs and send a
message back that the file is ready to be taken by the front servlet.
