The JDF client sends inbound messages to PRISMAsync. PRISMAsync sends outbound messages to the JDF client.
By default, inbound JMF messages use port 8010 for HTTP. You can change the port in the Settings Editor. The selected port must be available. PRISMAsync verifies that the port is not allocated to another feature (e.g. raw socket) when you change the port.
For outbound messages, the port can vary. The JDF client specifies a port for outbound messages in the URLs submitted to PRISMAsync.
Examples are the ReturnJMF in the command SubmitQueueEntry or the subscription URL in the query QueueStatus.
