Hi, from some recent messages on the jython lists it seems that different people/groups are starting to work on recreating some of the necessary software components in order to port Zope or a create a similar compatible framework on top of Java/Jython. Here's a link to latest related thread: http://aspn.activestate.com/ASPN/Mail/Message/Jython-dev/712337 Jeremy has already chimed in, my personal position is to help them as all other jython users, fixing incompatibilities with CPython and answering to questions. Nothing special. I can imagine that one of the big problem could be restricted execution (if Zope uses that), admitted that any C code functionality can be rewritten in Java. If the PythonLabs have an "official" position/opinion on this and in particular on the last quite speculative message (from Joseph Grace) in the thread, they may post something. I can say something about technical aspects, but I don't feel that I should channel/or invent PythonLabs opinions. regards, Samuele Pedroni.
