MQ 6, AIX 5.2, java 1.3.1
When I set the hostname variable to localhost
MQEnvironment.hostname = "localhost";
I am getting the following error when creating the QMGR object
mqQueueManager = new MQQueueManager(strQueueManager);
MQJE001: An MQException occurred: Completion Code 2, Reason 2059
MQJE011: Socket connection attempt refused
MQJE001: An MQException occurred: Completion Code 2, Reason 2059

at AcctCode1.main(AcctCode1.java:437)
when I replace it with IP or the actual host name
MQEnvironment.hostname = "xxx.xxx.xx.xx";
Its working fine.
Any help is appreciated. |

Hi,
are both localhost and the host name resolving to the same ip if you ping them ?
Greetings

| When I ping localhost and hostname , I am getting different Ips, in the sense,Ping localhost goes to the loopback and ping <hostname> is working. |

Any reason why you're using such an old level of java ? MQ v6 comes with java 1.4. I'd get the latest. |

| Is the MQ listener running on the loopback address? I.e. can you "telnet localhost <listener port>"? |

Or the listener is configured on a specific IP and not on *. |

True. I just figured that he knew the correct port...

When I start the listener as follows
runmqlsr -m QMGR -t TCP -p 1414 -i <hostname> &
I am able to connect to the QMGR using rfhutil and explorer.
When I start the listener as follows
runmqlsr -m QMGR -t TCP -p 1414 -i localhost &
I am not able to connect to the QMGR using rfhutil and explorer. |

That's great. I'm assuming from this statement that you no longer have a problem?
edit: And I assume you've read the manual, and understand what the parameters are and how they change the behaviour of runmqlsr? Also it would be worth doing some background reading on TCP/IP if you don't don't understand why your two scenario's above give the results that they do.
