Sierra,

Hi, i just wanted to share a very simular situation that we are going through now, and see what you think. I am in the opposite box though, migrating from a J2EE system based around BEA's Weblogic Server, to a pre-existing Perl backend, while maintaining the JSP/Servlet GUI. The way that we decided to handle this is by having the database be our main way of communicating between the two. Essentially, our servlets gather all of the data, our DAO's drop them off in the tables, and a perl translator comes along and formats them for the backend and drops them in Job Tables. We never really put any thought into having java and perl get along any other way, so i would be interested to hear how it works out for you, and anyone elses experiences. Good luck!
