I've been experimenting with what's possible in terms of having mod_perl interface with a system of business logic rather than a relational database. ie. I am try to find the find the mod_perl equivalent of Java's EJB tier in the following: (web brower + servlets) <---> (ejb) <---> (relational dbms) I've searched CPAN. Here are some better candidates: RPC::PlClient/PlServer/Simple, XMLRPC/SOAP, CORBA::ORBit/Mico. The most promising route seems to be a CORBA interface since such objects could be easily used by other systems. The feeling I'm left with is that although these could be used to implement a middle tier, it ain't exactly the playground filled with toys that J2EE has become. So I'm interested... Has anyone had success with implementing a middle tier for mod_perl? What with? And how successful was it? Matthew
