3.6. Overview of How the "Hello World" Quickstart Works
Figure 3.1. Image
- The JBoss Enterprise SOA Platform server is launched in
Window1and then theFirstServiceESB:SimpleListenerservice is added to the Service Registry service when the helloworld quickstart is deployed. - A JMS client sends an ESB-unaware "Hello World" message, (it is a plain
Stringobject), to the JMS Queue (queue/quickstart_helloworld_Request_gw). - The JMS Gateway Listener receives the ESB-unaware message and creates from it an ESB-aware message for use by ESB-aware end-points.
- The
JMS Gateway Listeneruses theservice registryto find theFirstServiceESB:SimpleListenerservice's end-point reference (EPR). In this case, the EPR is thequeue/quickstart_helloworld_Request_esbJMS queue. - The
JMS Gateway Listenertakes the new ESB-aware message and sends it to thequeue/quickstart_helloworld_Request_esbJMS queue. - The
FirstServiceESB:SimpleListenerservice receives the message. - The
FirstServiceESB:SimpleListenerservice extracts the payload from the message and outputs it to the console.
