This is an urgent requirement. Please help..!!
You can leverage the "large" message support in HornetQ (the JMS implementation in Wildfly) to put the contents of a file into a JMS message. See the documentation for more details.
Also, if you have urgent requirements then it may be better to use JBoss EAP with a Red Hat support subscription so you can get answers to your questions within a guaranteed time-frame rather than relying on a community forum such as this.
I'll look into JBoss EAP Option.
