Each JMS connection can be created as:

Internal JMS connection can be:
Externalized: See Externalizing Internal JMS Connections.
Exported: See Exporting Internal JMS Connections.
External (shared): See External (Shared) JMS Connections.
External (shared) JMS connection can be:
Linked to the graph: See Linking External (Shared) JMS Connection.
Internalized: See Internalizing External (Shared) JMS Connections.
Edit JMS Connection Wizard is described in Edit JMS Connection Wizard.
