Re: [Jython-dev] Strange

Hi George,

I tried it with lines commented out where something was missing (i.e.-
test2a), but it seemed to work fine.

I have not seen the error, I am curious about your initialization in
the Java classs though.  See test2run changes below...

You could try setting python.home and python.path...

import org.python.util.PythonInterpreter;
import org.python.core.*;
import java.util.*;

public class Test2Run {
	public static void main(String[] args)
		throws PyException
	{
		PythonInterpreter interp;
		Properties props = new Properties();
		props.setProperty("python.home","/usr/local/jython-2.0/");
		props.setProperty("python.path", "/home/modules:scripts");
		PythonInterpreter.initialize(System.getProperties(), props,
                                             new String[0]);
		interp = new PythonInterpreter();
		interp.exec("import Test2app");
		interp.exec('Test2app.go("whatever out should be") ');
	}
}

Just a guess.  Good luck.
