Manually checking the MQ Version information in the WebSphere MQ JAR files

Manually checking the information in the WebSphere MQ JAR files 
Alternatively, you can check a specific JAR installed as part of WebSphere MQ to find out the version information. The JAR to check is shown below: 

WebSphere MQ classes for Java: com.ibm.mq.jar 
WebSphere MQ classes for JMS : com.ibm.mqjms.jar 

Both of these JARs are located in the directory MQ_INSTALLATION_PATH/java/lib. 

Once the JARs have been located, follow the procedure below: 

1) Unjar the appropriate JAR using one of the commands shown: 

WebSphere MQ classes for Java: 
#jar -xvf com.ibm.mq.jar 

WebSphere MQ classes for JMS: 
#jar -xvf com.ibm.mqjms.jar 

2) Enter the uncompressed jar directory. This will contain a subdirectory called META-INF, which has a file in it called MANIFEST.MF. 

3) Open this file, and look for a line similar to the ones shown below. These lines indicate which version of the WebSphere MQ classes for Java or classes for JMS are being used by your application: 

WebSphere MQ classes for Java - com.ibm.mq.jar 
Specification-Title: WebSphere MQ classes for Java 
Specification-Version: 7.1.0.0 

WebSphere MQ classes for JMS - com.ibm.mqjms.jar 
Implementation-Title: WebSphere MQ classes for Java Message Service 
Implementation-Version: 7.1.0.0 - k000-L111005.1
