i have java program to find the Queue depth. java program refers to libraries present in /opt/mqm/java/lib.
I am calling this java program from ESQL. i dont want to deploy this jar files to the execution group. instead i would like to create the jar file for this java program and upload all jar files in /opt/ibm/mqsi/shared-classes folder.
but as MQ util jar files are already present in the /opt/mqm/java/lib path/, i dont want to upload these MQ jar files in /opt/ibm/mqsi/shared-classes. instead i would like to add these jar files to classpath env variable. and i will upload only one jar file i.e. generated from Queue depth java program.
my question is:
Can any one help how to add these required /opt/mqm/java/lib jar files to CLASSPATH permanently in Linux???? |

You are going completely the wrong way about this.
There is likely a global design issue problem here. Can you please answer the following question:
Why are you looking for the qdepth in a flow?

we have a requirement to monitor the error Queue and send email notification. |

This is what monitoring software is for (BMC (QPasa), Tivoli(Omegamon), etc...). The broker is not to be used for such a task.

Also, there's nothing different about putting classes on the CLASSPATH for Broker than for anything else.
And you shouldn't anyway. There are a number of reasons why shared-classes is a better choice.
Thirdly, whether you put the JAR on CLASSPATH or not doesn't change anything about whether classes that are included in the jar are loaded or not. If you don't want to use MQ classes that are in your JAR, then simply don't PUT them in your JAR.
And DON'T use Broker to monitor BROKER. |

I don't understand.
You update the CLASSPATH by updating the CLASSPATH.
There's nothing more to say, really. |

Okay.
There is more to say.
Again, DO NOT USE BROKER TO MONITOR ITSELF.
If you really insist on writing your own code to do your own monitoring, because you are mistaking cost for expense, then write stand alone code.
There are LOTS of reasons why ALL of the monitoring tools out there do not run in the container they are monitoring.
If you do this, you will experience LOTS of trouble. YOU HAVE BEEN WARNED.
Secondly.
DO NOT USE CLASSPATH.
Shared-classes is easier, better and more visible. And safer, too. |

I saw a guy try to change the oil in his car with a hammer once.
My dad used to tell me: choose the right tool for the job.
Toolman Tim Taylor from Home Improvement always got bested by his co-hort, Al.
I would encourage you to take a holistic view of the world, and implement a strategic solution that manages application state the right way.
My favorite always was HP OpenView which is now HP Operations Manager software. If you have money, you could buy Tivoli.
If you have no money, you could try JMX tooling (jconsole) that is a standard part of all JREs.
See this link: "Using JConsole to Monitor applications"
http://java.sun.com/developer/technicalArticles/J2SE/jconsole.html
How long have you been developing Java applications? I'm surprised you did not know about jconsole?

This event seems to have made an impression:

As does the TV show. Do you identify with Al?

I am more the Tim-type. My brother, 3 years junior, would be more the Al-type.
contact admin that more closely represent me in real life: Caveman Maurice (Kate's old boyfriend) (you should see the ABC Cavemen episodes on youtube for this info), Emeril Lagasse (famous chef), Ronald Reagan, and Doug Heffernan (IPS delivery driver).
