I have Java service (EJB) that implemented functionality required for Perl application.
Unless I’ll find better solution, plan is to put SOAP facade on top of EJB and consume it from Perl using SOAP:Lite. There seems to be no compatibility issues between SUN SOAP and SOAP:Lite
http://java.sun.com/wsinterop/sb/r2/results.html, but I’m wonder is there other ways that might be better from performance/ easy-of-implementation points of view.

PS Unfortunately I can’t use beta products like http://www.cpan.org/modules/by-module/Inline/Inline-Java-0.33.readme
