This is an implementation of JSON-RPC 1.1 over Stomp protocol in Perl and PHP. It's designed to work with ActiveMQ version 5.2 or more (mainly).
It works very fast, synchronous or asynchronous. It provides reliable RPC call. I use it for both PHP and Perl, PHP is web front-end (presentation and form), makes call to the back-end Perl process (bussiness processing), connect to the Database (Oracle).
Helping by ActiveMQ infrastructure, you can make a completely high available, load balancing, distributed system.
