problems using javaclass.classhook, HELP!

[Marcin Paczek]

I would like to import Java class in Python.

For this class:

SampleJavaClass .java

public class SampleJavaClass {
    public static void main(String args[]) {
         System.out.println("Hello world");
    }
}

everything is OK. What I do is:
javac SampleJavaClass .java
java SampleJavaClass (works OK)

then I can access this class in Python, like this:

#!/usr/bin/env python

import javaclass.classhook
import SampleJavaClass

class JavaWrapper(object):
    def __init__(self):
        pass

    def main(self):
        hook = SampleJavaClass.SampleJavaClass()
        hook.main([])


if __name__ == '__main__':
    wrapper = JavaWrapper()
    wrapper.main()

but:

when my Java class (.java) uses some imports, lets say:

SampleJavaClass .java

import java.sql.*;

public class SampleJavaClass {
    public static void main(String args[]) {
        try {
            // just for tests
            throw new SQLException();
        }
        catch(SQLException e) {
            System.err.println("Got exception: " + e.getMessage());
        }
        System.out.println("Hello world");
    }
}

then after doing exactly the same thing as in the first case (the same python code) I get the following error:

-----
Traceback (most recent call last):

raise ImportError, "No module named " + mname
ImportError: No module named java.sql

Can anyone help me? My CLASSPATH is set and points to the rt.jar, I also tried in python code to sys.path.append (<rt.jar>) but it did not help.

Thank You for any hints.
