Hello!
I use to work using C++, but recently I got request to make an MQ client application using Java. C++ makes difference between client and binding connection, by linking with different libraries.
I have set MQEnvironment.hostname as documentation says:
The TCP/IP hostname of the machine on which the MQSeries server resides. If the hostname is not set, and no overriding properties are set, bindings mode is used to connect to the local queue manager.
Further, to ensure client connection I have set :
MQEnvironment.properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_CLIENT);
Finally I have set MQEnvironment.channel to the name of the server connection channel on the remote queue manager, even MQEnvironment.port=1414; although it is default, but I still receive this:
java.lang.NoClassDefFoundError: com/ibm/mq/MQSESSIONServer
at com.ibm.mq.MQQueueManager.<init>(MQQueueManager.java:241)
at drugi.MQSample.main(MQSample.java:31)
Exception in thread "main"
I do not have installed this class, since I have installed only MQSeries client for Windows, but I do have com/ibm/mq/MQSESSIONClient class imported and included. Why does not the application try to use this class, instead off looking for MQSESSIONServer?
What am I missing? Help please.
Thank you in advance. |

Hello!
First of all, sorry about double post.
I did copy mqhash.java example and it does not work too,
it gives the same error report.
Any ideas? |

My guess would be that you have your classpath messed up or you are running with older jar files. I'm running at WMQ 5.3 CSD8 and my classpath looks like:
| Code: |
set CLASSPATH=C:\WMQ\Java\lib\providerutil.jar;
C:\WMQ\Java\lib\com.ibm.mqjms.jar;
C:\WMQ\Java\lib\ldap.jar;
C:\WMQ\Java\lib\jta.jar;
C:\WMQ\Java\lib\jndi.jar;
C:\WMQ\Java\lib\jms.jar;
C:\WMQ\Java\lib\connector.jar;
C:\WMQ\Java\lib\fscontext.jar;
C:\WMQ\Java\lib\com.ibm.mq.jar;.; |
You probably don't need all of these. I run jms as well as base java so I include its jars as well. |

Hello bower5932!
I see I didn't post any new information on this.
Yes, everything works fine with WMQ 5.3 client for Windows, it
didn't work with MQ 5.1 client. Key of the problem was connector.jar.
For me this definition is sufficient:
set CLASSPATH=.\;C:\Program Files\IBM\WebSphere MQ\Java\lib\connector.jar;C:\Program Files\IBM\WebSphere MQ\Java\lib\com.ibm.mq.jar;
Thank you for your effort. |
