[Jython-users] How to call Python function that takes a parameter

[Subodh Garg-S. <sub...@ss...>]

Hi All,

Here is the example Python code in hello.py and Java code. I am able to invoke run function of Python class Hello as given the code. I need help in calling "run2" function of Python in Java.

Thanks,
Subodh

class Hello:
    __gui = None

    def __init__(self, gui):
        self.__gui = gui

    def run(self):
        print 'Hello world!'

    def run2(myname):
        print myname

Here is my Java code:
import org.python.core.PyInstance;
import org.python.core.PyString;
import org.python.core.PyObject;
import org.python.util.PythonInterpreter;
import java.lang.*;
import java.util.*;


public class InterpreterExample
{

   PythonInterpreter interpreter = null;


   public InterpreterExample()
   {
      PythonInterpreter.initialize(System.getProperties(),
                                   System.getProperties(), new String[0]);

      this.interpreter = new PythonInterpreter();
   }

   void execfile( final String fileName )
   {
      this.interpreter.execfile(fileName);
   }

   PyInstance createClass( final String className, final String opts )
   {
      return (PyInstance) this.interpreter.eval(className + "(" + opts + ")");
   }

   public static void main( String gargs[] )
   {
      InterpreterExample ie = new InterpreterExample();

      PyInstance hello = ie.createClass("Hello", "None");

      hello.invoke("run");
   }
}
