[Jython-users] Embedding question again..?

[Pulak P. (UAB) <Pul...@ua...>]

Hi,

 I am tring to use Jython for a scripting application to configure a =
External Device.

The idea is  to provide user the flexibility of writing scripts in =
jython while the GUI and other aspects of external communications etc =
are handled in Java.

 Once the GUI is ready and the communication class is instantiated the =
control will be passes to a jython script.=20

 The communication Object ( which is a java object) will be passes on =
to the Jython script which will then call "Send(Command)" interface for =
example.=20


To do I am doing the following

Java side
--------------
//jptComm object is already instantiated and setup. It has an interface =
send(string).

PythonInterpreter interp =3D new PythonInterpreter();
    try{
        interp.execfile(fileName); // where filename is the name of =
jython script ( runscript.py)
    }
    catch( PyException except)
    {
      System.out.println("Error occured in exec file");
    }
    try{
         interp.exec("run(jptComm)"); // where the jptComm in the =
communication object.
          //interp.exec("run(2)"); //instead if I pass builtin types =
like int or string it works fine.
    }
    catch( PyException except)
    {
      System.out.println("Error occured in EXEC");
      System.out.println(except.toString());
    }
  }

Jython side
---------------


import java
import jpitool.jpitoolCommunicator

def run(jcp):
	print 'xyz'
	#jcp.send('ls')


if __name__ =3D=3D '__main__':
	run(2)
________________________________________________________________________=

If I execute the Java code and call the run function from there with =
communicator object as the argument it always gives me a
"NameError" exception
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Error occured in EXEC
Traceback (innermost last):
  File "<string>", line 1, in ?
NameError: jptComm
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

If i use any standard data type like int or string  for eg " =
interp.exec("run(2)") " it works fine.
Can someone help. Any information on the same will be helpful.
