This sample demonstrates the use of a full registry-based ESB configuration, to start a remote configuration from multiple ESB instances in a clustered environment. Here the Synapse configuration of a given node hosting the ESB simply points to the registry and looks up the actual configuration by requesting the key
Full registry-based configuration is not dynamic at the moment; it is not reloading itself.
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_11.xml is available in the
To build the sample
Start the ESB with the sample 11 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
Analyzing the output
When you analyze the debug log output on the ESB console once the client is executed, you will see the following:
synapse.xml that is loaded when the sample is run is:
