From the error messages posted I cannot see any reference to the outdated WmJMSAdapter-Package (latest known version 6.1 SP1).
More likely this seems to be a configuration issue in IS:
Please check under “Settings → Messaging → JMS Settings” and “Settings → Messaging → JNDI Settings” for details.
Are you using Broker or Nirvana/Uniiversal Messaging as Transport?
PE in this case stands for Process Engine. This JMS-Connectivity is used by PE/PRT internally.
If this does not help, please share more details.
