This configuration file  synapse_sample_657.xml is available in the <ESB_HOME>/repository/samples directoryThe above sample configuration uses two data sources and database instances to point to the sample databases. You have to manually create these in your environment for the sample to work.

To build the sample

  1. Start the ESB with the sample 657 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."Create the required database instances, see Setting up the Physical Database

  2. Set up the Derby database server, see Setting Up the Derby Database.
  3. Create the two sample XA data sources, see Adding Datasources and Transaction Examples.
  4. Start the Axis2 server. For instructions on starting the Axis2 server, see Starting the Axis2 server.

  5. Deploy the back-end service SimpleStockQuoteService. For instructions on deploying sample back-end services, see Deploying sample back-end services.
