Class not found exception when trying to establish MQ server connectivity
Hello,
I am trying to do POC on MQ. I have imported the below jar files into PEGA.
com.ibm.mq.header.jar
com.ibm.mq.jar
com.ibm.mq.commonservices.jar
After importing these files, I have had the server restarted and created a MQ server instances and provided details on required fields. When I am trying to hit the Test connectivity button, getting a Class not found exception. Attaching screen shot for reference.
NOTE: the class that is shown in exception message has been imported as part of com.ibm.mq.jar file.
What am I missing? Thanks in advance.

Hello,
Starting from IBM MQ v9, connector.jar and dhbcore.jar are not shipped with the installation, they have been removed. Is this list accurate for IBM MQ v9 as well ? Also I am working in PEGA 8.2.4.

Hi Vinay,
The class which is throwing error exists in com.ibm.mq.jar.Is that import successful?Can you please verify pr_engineclasses table, check for these jars in pzjar column.If it is not present then you need to reimport it.
Please install other jars as well from below list.Download connector & dhb core jar from outside if it is not shipped.Restart both prpc & MQ server & then verify.
- com.ibm.mq.commonservices.jar
- com.ibm.mq.headers.jar
- com.ibm.mq.jar
- com.ibm.mq.pcf.jar
- com.ibm.mq.jmqi.jar
- connector.jar
- dhbcore.jar
- fscontext.jar
- jms.jar
- com.ibm.mqjms.jar

Hello Abhinav,
I have verified the pr_Engineclasses table and the import for com.ibm.mq.jar is successful. Which version of jar file should I install for dhbcore and connector.jar files? Is there any link to get the latest version?
Also when I do the test connectivity now, I am not able to establish the initial context. Attached the screenshot and log file details.
Please advise .
Thanks,

Hi Vinay,
I can see below error in logs.
Caused by: java.io.IOException: Broken pipe at sun.nio.ch.FileDispatcherImpl.write0(Native Method) ~[?:1.8.0_212] at sun.nio.ch.SocketDispatcher.write(SocketDispatcher.java:47) ~[?:1.8.0_212
Can you please verify whether your MQ server is up and running or not.Can you try to consume it from any other application.Is it accessible.Please check connectivity from pega server to MQ server using ping command.
Thanks,

Hello,
I am able to ping MQ Server with no packet loss and below are the stats.
ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2002ms
rtt min/avg/max/mdev = 3.905/4.687/6.207/1.076 ms
Also I am working in a POC environment and do have other applications that can access this.
Thanks,
Vinay
