This sample demonstrates the simple content-based routing of messages where a message is passed through the ESB in the Dumb Client Mode. The ESB acts as a gateway to accept all messages, and then performs mediation and routing based on message properties or content.
For a list of prerequisites, see Prerequisites to Start the ESB Samples.
Building the sample
The XML configuration for this sample is as follows:
This configuration file
synapse_sample_1.xml is available in the
To build the sample
Start the ESB with the sample 1 configuration. For instructions on starting a sample ESB configuration, see Starting the ESB with a sample configuration.
The operation log keeps running until the server starts, which usually takes several seconds. Wait until the server has fully booted up and displays a message similar to "WSO2 Carbon started in n seconds."
Start the Axis2 server. For instructions on starting the Axis2 server, see Starting the Axis2 server.
Deploy the back-end service SimpleStockQuoteService. For instructions on deploying sample back-end services, see Deploying sample back-end services.
Now you have a running ESB instance and a back-end service deployed. In the next section, we will send a message to the back-end service through the ESB using a sample client.
Executing the sample
The sample client used here is the Stock Quote Client, which can operate in several modes. For further details on this sample client and its operation modes, see Stock Quote Client.
To execute the sample client
Run the following command from the
<ESB_HOME>/samples/axis2Clientdirectory, to execute the Stock Quote Client in the Dumb Client Mode.
Analyzing the output
Analyze the output debug messages for the actions in the Dumb Client Mode.
You will see the ESB receiving a message for which the ESB is set as the ultimate receiver. ESB performs a match to the path
/StockQuote based on the
