| I'm a little stumped by this problem. I'm rolling out the mq client to some of our developer's desktops and I am able to connect to a queue manager, run the sample put/get programs (amqsputc etc.) as well as the sample java mq test program, mqivp. All ran fine so it appears all the environment variables are correct. I then ported the java source code from one of our servers to their desktops and recompiled and ran and it came back with this mqjbnd05 error. Why would the sample java program that IBM provides run but when I attempt to execute my own code, which runs fine on multiple server environments then not work? I've added all jars in the mq java lib to the classpath in an attempt to fix the problem and checked the lib_path. No dice. Any thoughts would be appreciated. |

| You can search here on mqjbnd05 and get numerous hits. My guess is that you are attempting to connect in bindings mode from a client and it's not working. It probably worked on your other systems because you had the full qmgr installed. |

| Thanks for the reply. How do I change the program to connect not using binding mode? |

IIRC change the transport type and supply the client connection details.

Got it.
For anyone searching this in the future, to enable the client connections in a java program you must enter these lines in your code (see "Using Java" manual for more info).
MQEnvironment.hostname = "hostname";
MQEnvironment.channel = "client.channel"; |

Hey I was also getting the same error and was able to resolve the problem by using
MQENviorment : Host
MQEnvironment.channel
MQEnvironment.port
in the code... But I think its not the permanent solution to the above .... It clearly shows that the enviornment variable is messed up.... As I was able to run the same program in some other computer without any error and without using
MQENviorment : Host
MQEnvironment.channel
MQEnvironment.port
So if there is any permanent solution then Pls do post it ..
Pls Note : I have gone through MQ Manaual --- chapter 2 --- Enviornment Variable --- TBL 4 |

You need to specify hostname, channel and port to establish an MQ client connection in any language.
The Java API doesn't use the OS environment. It uses the MQEnvironment class.
I don't see what your confusion is?

Maybe he should use a channel table?

The prob is I have hard coded the env variable .. which is not the correct way of doing it .. when we install mq the env variable are set in the system env setting .. which generally helps .. but in my case nothing seems to work ... Might be I am missing something .. I am not sure but for time being I am hard coding the env variable .. If I or nebody out there get's ne solution then pls do post it ....  |

I assume you have read the Java manual / javadoc? (you mentioned reading it earlier)
Have you spotted the MQQueueManager constructor that takes a Hashtable of properties?
Have you then looked at page 120 (v6 online pdf version) and read about what you can do using that properties hashtable? |

OMG! Doesn't anyone buy and read books or take courses anymore? If you have a programming job then you probably have a college or university degree? 
This is Java 101 programming course stuff. How in the world did you get a job programming Java when you can't simple setup code to read a property file and then use those values. OMG!
Do the following:
1) Create a property file ("myprg.properties") in the same directory as your Java source code. i.e.
| Code: |
mq.qmname=MQA1
mq.hostname=10.10.10.10
mq.channelname=SYSTEM.DEF.SVRCONN
mq.port=1414 |
2) In your initialization code add the following:
| Code: |
Properties props = new Properties();
FileInputStream in = new FileInputStream("myprg.properties");
props.load(in);
_qMgrName = props.getProperty("mq.qmname");
_hostname = props.getProperty("mq.hostname");
_channelName = props.getProperty("mq.channelname");
_portNumber = props.getProperty("mq.port");
props.close(); |
3) Finally, use those values:
| Code: |
MQEnvironment.hostname = _hostname;
MQEnvironment.channel = _channelName;
try
{
MQEnvironment.port = Integer.parseInt(_portNumber.trim());
}
catch (Exception E)
{
MQEnvironment.port = 1414;
} |
Hope that helps and please read some sort of beginner's guide to Java manual/book.
