If a BAR file contains JAR files, you can associate keywords with the JAR files.
Read about keywords in Message flow version and keywords.
# META-INF/keywords.txt
$MQSI modified date = 3 Nov MQSI$
$MQSI author = john MQSI$
This content means that the keywords "modified date" and "author" are associated with the deployed file compute.jar in applications that use the IBM® Integration API, including the IBM Integration Toolkit.
You have now added keywords to your JAR file.
When you have added keywords to your JAR file, you can display them in the BAR file editor; for more information, see Version and keyword information for deployable objects .
