It seems that the Zope developers is not really interesting by a java integration - Why ? At least, ejb & servlet are well used in a lot of companies. So, a product like Zope is usefull for them if and only if it can call some requests to some java components from zope.
Most of those companies have made a significant investment in Java technology, in hardware, software and human resources (train your people) and learning another environment, another programming language is not always a sound investment if your people talk Java as well their native language. There are 'political' reasons as well, won't get into that. Personally I would have a good look at xmlBlaster, an open source, XML/Corba based MOM (message oriented middleware) that supports Java as well Python (among other languages). Seems to support XML-RPC (Zope does too). Have Zope talk to xmlBlaster and it could interface with almost any other product out there, whether it's Java, CORBA or XML based. Very cool stuff, haven't tried it with Zope yet though. Check it out: http://www.xmlblaster.org/ HTH Jonathan
