That would be great, but I don't know how. I am doing roughly this:
PythonVM.start(programName)
vm = PythonVM.get()
vm.instantiate(moduleName, className);
I tried also:
PythonVM.start(programName, new String[]{"-c", "import
sys;sys.path.insert(0, \'/dvt/workspace/montysolr/src/python\'"});
it is failing on vm.instantiate.... when Python cannot find the module

sorry, i meant sys.path, not sys.argv
