Where to Place Custom and Third-Party Jar Files
If you want to use any custom or third-party jar files with an Integration Server instance, store them in the Integration Server_directory \instances\instance_name\lib\jars\custom directory. For example, if you want to use a third-party JMS provider client, a third-party JNDI provider, or custom JDBC drivers for WmDB, place the client libraries in the custom directory. Review the documentation for your third-party application to determine an exact list of required jar files.
Note: Any jar files you place in this directory can be migrated using the Integration Server migration utility.
Note: You can make jar files available to all server instances by placing them at the common level in the IntegrationServer\lib\jars\custom directory.
