Issue2059

java test code:
import java.io.IOException;
import java.util.Properties;

import org.python.core.Py;
import org.python.core.PyString;
import org.python.core.PySystemState;
import org.python.util.PythonInterpreter;

public class Tester {

    public static void main(String[] args) throws IOException {

        Properties props = new Properties();
        Properties baseProps = PySystemState.getBaseProperties();
        props.put("python.path", "/duitang/dist/sys/jython/Lib");
        props.put("python.home", "/duitang/dist/sys/jython");
        PySystemState.initialize(baseProps, props, new String[0]);

        PySystemState sys = new PySystemState();
        PythonInterpreter interp = new PythonInterpreter(Py.newStringMap(), sys);
        String rootPath = "/duitang/dist/app/trunk/java/japa/src/main/webapp";

        sys.path.append(new PyString(rootPath));
        interp.exec("import gzip");
    }
}

Most likely this is a CLASSPATH issue for the poster of this bug:
