You're tryin to create a pool of connections all with the same client id.
This isn't allowed. Only one connection can use a client id at once.

  | javax.resource.spi.CommException: javax.jms.JMSSecurityException: The login id has an assigned client id 'guest', that is already connected to the server!

You can use the jms resource adapter with a client id,
but only if you set the max-pool-size to 1
