MQ 5/6 had a class com.ibm.mq.MQException in the com.ibm.mq.jar file

Has this class been removed in MQ7? Since the MQ7 com.ibm.mq.jar file does not have that class.

It's not been removed.

It's just been moved.

Hi

As a non programmer what are the implications of this?

What I have found so far is that some programs no longer work after upgrade to MQv7 from MQv6.

tcserver is one that no longer works due to MQException in com.ibm.mq.jar being moved to com.ibm.mq.jmqi.jar...

I have also had to upgrade things like jt400

I have even had to leave the MQv6 libs in place and point some programs to the old libs to keep them working..

Do we basically need to recompile all our programs that used the com.ibm.mq.jar and include com.ibm.mq.jmqi.jar

Thanks

Just had to post the question and then figure it out

seems I just needed to copy the .jar file to the TCServer share directory.

Which got me almost there now I get

java.lang.NoClassDefFoundError: com.ibm.mq.MQQueueManager

did a grep on com.ibm.mq.MQQueueManager and it is in the .jar in the shared directory...

Thanks

you should not mix and match jars across releases.
Either use only MQV7 jars on the classpath or use only MQV6 jars on the classpath.

And yes you should review your code when moving from MQV6 to MQV7 as some classes have been deprecated and replaced by others... and some work a little bit differently...

Have fun

Hi

thanks for that

I agree that mixing versions is not good however what I have done is created a folder with the MQ V6 Java and pointed a single OLD application to it. This should not impact any other apps or any new apps

Sometimes finding out how old in house apps are put together is a large task and work arounds need to be done or we all would still be on MQ5.1
