Now I'm running into trouble loading jcc in python, because it can't find the JVM dll: from _jcc import initVM ImportError: DLL load failed: The specified module could not be found. If I attempt to use jcc to compile Lucene, I get the pop-up box saying, "This application has failed to start because jvm.dll was not found. Re-installing the application may fix this problem."This is kind of nasty. Turns out I need $JAVAHOME/jre/bin/client on my PATH before "import jcc" will work in Python. This is the logical equivalent of the LD_LIBRARY_PATH problem on Unix.
Yes, very much so.
So, we need to figure out how to do this for Windows Python. We really want Python (rather, the JCC __init__.py file) to look in the Windows registry and do the right thing with what it finds there (basically, adding the right location for the jvm.dll to sys.path), before it attempts to import either "jcc" or "_jcc".
It's not sys.path (that's where PYTHONPATH ends up), it's the env's PATH or, more precisely, the process's executable search path that needs to be updated. I don't know of a linker way to do this on Windows. Once the process has started, my understanding is that it's too late already.
In Chandler, we have a starter process that starts python after setting the proper search path.
