[omniORB] Problem with omniORBpy and NamingService

[marc]

I use omniORBpy with omniORB3 on Linux. I work with the NamingService. If I put the server and the client on the local host, it ru very well. But if I put the server on a remote host on the same network, the exception "omniORB.CORBA.COMM_FAILURE: Minor: 32, Completed: COMPLETED_NO." from the client, appears. I tried to change the configuration in the omniorb.cfg file, but I always obtained the same result.
I don't understand why it's not working.

I put my scripts below:


##################### IDL

module User {
  interface Information {
    readonly attribute string name;
    readonly attribute string surname;
    attribute float salary;

    string getName();
    string getSurname();
    float getSalary();
    float increaseSalary( in float inc_value );
    float decreaseSalary( in float dec_value );
  };
};

##################### Server.py

import sys
from omniORB import CORBA, PortableServer
import User, User__POA
import CosNaming

# Define implementation of the Information interface

class Information_s ( User__POA.Information ) :
    def __init__ ( self ):
        self.name = "Eric"
        self.surname = "Bianchi"
        self.salary = 100.0

    def getName ( self ):
        print """getName"""
        return self.name

    def getSurname ( self ):
        print """getSurName"""
        return self.surname

    def getSalary ( self ):
        print """getSalary"""
        return float(self.salary)

    def increaseSalary ( self, inc_value ):
        print """increaseSalary"""
        self.salary = self.salary + inc_value
        return float(self.salary)

    def decreaseSalary ( self, dec_value ):
        print """decreaseSalary"""
        self.salary = self.salary - dec_value
        return float(self.salary)

# Initialise the ORB:
orb = CORBA.ORB_init(sys.argv, CORBA.ORB_ID)
poa = orb.resolve_initial_references("RootPOA")

# Create an instance of Information_s and an Information object reference:

ifts = Information_s()
ift = ifts._this()
print """New Information object has been created"""
print ift

# Obtain a reference to the root naming context:

obj         = orb.resolve_initial_references("NameService")
rootContext = obj._narrow(CosNaming.NamingContext)

if rootContext is None:
    print 'Failed to narrow the root naming context'
    sys.exit(1)

# Bind a context named "test.my_context" to the root context:

name = [CosNaming.NameComponent("test", "my_context")]
try:
    testContext = rootContext.bind_new_context(name)
    print "New test context bound"

except CosNaming.NamingContext.AlreadyBound, ex:
    print "Test context already exists"
    obj = rootContext.resolve(name)
    testContext = obj._narrow(CosNaming.NamingContext)
    if testContext is None:
        print "test.mycontext exists but is not a NamingContext"
        sys.exit(1)

# Bind the Information object to the test context:
name = [CosNaming.NameComponent("UserInformation", "Object")]
try:
    testContext.bind(name, ift)
    print "New UserInformation object bound"

except CosNaming.NamingContext.AlreadyBound:
    testContext.rebind(name, ift)
    print "UserInformation binding already existed -- rebound"

# Activate the POA
poaManager = poa._get_the_POAManager()
poaManager.activate()

# Block for ever (or until the ORB is shut down)
orb.run()

#################### Client.py

try:
    obj = rootContext.resolve(name)

# Narrow the object to an User::Information

print ift

    print "Object reference is not an User::Information"
    sys.exit(1)

#Invoke getName operation
print 'the user is :\n'
name = ift.getName()
print 'Name: ', name

surname = ift.getSurname()
print 'Surname: ', surname

salary = ift.getSalary()
print 'Salary: ', salary

x = ''
while not x:
    x = int(raw_input('Increase or decrease the salary? 1 or 2:'))

    if x == 1:
        y = ''
        while not y:
            y = float(raw_input('salary increased value;\n'))
            salary = ift.increaseSalary(y)
            print 'The new salary is:\n', salary

    if x == 2:
        y = ''
        while not y:
            y = float(raw_input('salary decreased value;\n'))
            salary = ift.decreaseSalary(y)
            print 'The new salary is:\n', salary

The client answer me:

Traceback (innermost last):
  File "client.py", line 36, in ?
    name = ift.getName()
  File "User_idl.py", line 67, in getName
    return _omnipy.invoke(self, "getName", _0_User.Information._d_getName, args)
omniORB.CORBA.COMM_FAILURE: Minor: 32, Completed: COMPLETED_NO.
