I need to be able to call a Java servlet from a Rails app. I can NOT use  
JRuby. Has anybody successfully deployed their Rails app to Tomcat and  
gotten rewrite to send normal rails requests to a Mongrel cluster and  
send a servlet request (by url) to the servlet container?

I understand that Tomcat is slower than Apache and, of course, am  
concerned about performance, but I need to enable enterprise reporting  
through Jasper Reports and can’t get Ruby to talk directly to Java.
