Indeed, this is why I put that assertion there :-) It's a bit of guesswork what all the possibilities are there. I'll add support for arrays there. Andi..

Using JCC / PyLucene with JEPP?
New topic. I'd like to wrap my UpLib codebase, which is Python using PyLucene, in Java using JEPP (http://jepp.sourceforge.net/), so that I can use it with Tomcat. Now, am I going to have to do some trickery to get a VM? Or will getVMEnv() just work with a previously initialized JVM? Bill
