Table of Contents


This sample demonstrates how sequences and endpoints can be fetched from a local registry so that it is possible to have the sequences and endpoints as local registry entries including file entries.


For a list of prerequisites, see Prerequisites to Start the ESB Samples.

Building the sample

The XML configuration for this sample is as follows: 

Code Block
<definitions xmlns=""
    <localEntry key="local-enrty-ep-key"
    <localEntry key="local-enrty-sequence-key">
        <sequence name="dynamic_sequence">
            <log level="custom">
                <property name="message" value="*** Test Message 1 ***"/>
    <sequence name="main">
            <sequence key="local-enrty-sequence-key"/>
                <endpoint key="local-enrty-ep-key"/>

This configuration file  synapse_sample_14.xml is available in the <ESB_HOME>/repository/samples directory.

To build the sample

  1. Start the ESB with the sample 14 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."

  2. Start the Axis2 server. For instructions on starting the Axis2 server, see Starting the Axis2 server.

  3. 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/axis2Client directory.

    Code Block
    ant stockquote -Dtrpurl=http://localhost:8280/

Analyzing the output

When you analyze the debug log output, you will see that the log statement for the fetched sequence of the local entry and the endpoint is fetched from the specified file at runtime and is cached in the system.
