How to use JacORB in Jython

Question

I want to write a CORBA test client in Jython and I select JacORB as ORB implementation. However I have a try for around 1 day and ORB.init can't be successfully in Jython and error log is:

======================================================================

ERROR: testEPAgentIsAlive (com.ericsson.xn.nbi.test.epagent_test.Test)

Traceback (most recent call last): File "/Users/AnkyHe/proj/workspace/EPAgentTest/src/com/ericsson/xn/nbi/test/epagent_test.py", line 18, in testEPAgentIsAlive orb = ORBFactory.initORB() INITIALIZE: org.omg.CORBA.INITIALIZE: can't instantiate default ORB implementation org.jacorb.orb.ORB vmcid: 0x0 minor code: 0 completed: No

The source code is as follows: from com.ericsson.xn.nbi.corbautil import ORBFactory from com.ericsson.xn.nbi.idl import EPAgentHelper from org.omg.CORBA import ORB from org.omg.CosNaming import NamingContextExtHelper import unittest

class Test(unittest.TestCase):

def setUp(self):
  pass

def tearDown(self):
  pass

def testEPAgentIsAlive(self):
  orb = ORBFactory.initORB()
  nc = NamingContextExtHelper.narrow(orb.resolve_initial_references('NameService'))
  server = EPAgentHelper.narrow(nc.resolve(nc.to_name('epagent')))
  self.assertNotEquals(None, server)


def testGetReference(self):
  pass
  #self.assertEquals('ftagent_ref', self.server.get_irp_reference('ftagent'))
