If you're deploying in a war, then stick the Lib directory in the "classes" dir (for example), and then point the python path at that directory with something vaguely like:

Properties props = new Properties();
String jythonPath = libDir.getFile().getCanonicalPath();
props.put("python.path", jythonPath);
PythonInterpreter.initialize(System.getProperties(), props, null);

In my case, "libDir" is a prop injected by spring:

<property name="libDir" value="classpath:Lib" />

So you'll need to grab the canonical path according to whatever framework you're working within.

Dunno if that helps?

I unzipped the jython package and I can run the jython jar using java –jar jython.jar.  The interpreter works fine.


What the instructions lack is how to copy the jython jar and resources elsewhere.  I don’t want to ship the entire jython zip file with my project; I want to place the relevant parts into a war file.


The #!/usr/bin/python is irrelevant – it’s there because the script has it, but it still doesn’t work without it.


The answer seems to lie in the lib directory – could you tell me how Jython loads resources from it?

Hi John,


Could you elaborate more on how you install Jython on your environment?

The first line looks like you are invoking jython from your default CPython instead of Jython.

The line 1: #!/usr/bin/python


Could you invoke Jython from your shell/command prompt with that setting?

I've copied the jython.jar file into my project but I guess I need the Lib directory too?  Does it go on the classpath?  Does Jython look in the current working directory?
