| I want to have my Java application running on one machine do a get/put with MQSeries installed on another machine. I downloaded the supportpac MA88: MQSeries classes for Java, wrote my java program with the required import statement, compiled it fine but when I attempt to run it, I got an error that The dynamic link library MQM.dll could not be found in the specified path ..... The MQM.dll isn't installed with the MA88 support pac. I think I would have to install an MQSeries server on my machine in order to access that. Shouldn't I be able to write a Java program running as a client on one machine and connect to MQSeries queue on a different machine without needing MQM.dll? Is there something else that I need to load on the machine that's running the Java application? Thanks in advance for any help.[/quote] |

If you want to run MQSeries as a client, then you need to install MQSeries client

The Java interfaces (for either the Java MQI or for JMS) can be installed and run without having to install the other client software. The confusion arises because the Java classes can be used to make either client (tcp/ip) connections or local connections via JNI and C. It looks like the application is attempting make a local connection instead of a client one, so the solution is to reconfigure the application to use client connections instead. For the Java MQI you do this either by setting the MQEnvironment or by configuring a properties hashtable passed to the MQQueueManager constructor (I'd recommend the latter approach). For JMS, the settings are on the connection factory.
Regards,
James. |

To run Java application on clent computer you need:
com.ibm.mq.jar - using MQ classes
com.ibm.mq.jar, com.ibm.mqbind.jar, com.ibm.mqjms.jar - using jms
Make sure that your application is not looking for local QMgr (if you provide correct hostname etc).

| There is an mqhash.java in the repository that sets the client environment up in a hash table. |

Or you can set the variables directly (for client mode).
To use client mode in your Java code, you need the following lines:
| Code: |
MQEnvironment.hostname = "192.168.10.200";
MQEnvironment.channel = "SYSTEM.DEF.SVRCONN";
MQEnvironment.port = 1414; |
later

| Thanks for everyone's reply. I set the MQEnvironment variables and it worked. |
