    how can I invoke a Java code?

    A friend of my write a Java program, and I want use it in my python
    program as a module. I searched the topic in Google and find maybe the
    better way is use GCJ to compile it. Is there any other way for me?
    the simple and speediness choice the better. thanks.

      If you want to run the Java program as a separate process, you can run
      "java -jar TheProgram.jar" .

      If you're wanting to interact with the code, your best option may be
      Jython, an implementation of Python in Java.

          I do have to interact with Java module, and when talk about Jython,
          since I use third parts of python modules I am puzzled about it.

                  If the speed is crucial, I suggest compiling the Java code with GCJ,
                  then write Python extension module for the Java library. This is how the
                  Lucene indexing library is ported to Python, see
                  http://pylucene.osafoundation.org/.
