The property is "python.cachedir", and you can set it in the call to
PythonInterpreter's initialize method.  Jython's registry file explains the
python.cachedir property.

        Properties props = new Properties();
        props.put("python.home", "/path/to/jython");
	props.put("python.cachedir", "/path/to/cachedir");
	PythonInterpreter.initialize(System.getProperties(),
	                             props, new String[0]);

sys.add_extdirs(directoryContainingYourJars) is the easy way.

For individual jars, you abuse the "public" status of packageManager and
addJar with the following (untested, sorry):

PySystemState sys = Py.getSystemState();
sys.packageManager.addJar("/usr/local/jakarta-tomcat-3.2.3/lib/parser.jar");
