This sample demonstrates how an HTTP inbound endpoint can act as a dynamic http listener. Many http listeners can be added without restarting the server. When a message arrives at a port it will bypass the inbound side axis2 layer and will be sent directly to the sequence for mediation.The response also behaves in the same way.


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

Building the sample

The XML configuration for this sample is as follows:

<definitions xmlns="">
    <inboundEndpoint xmlns=""
  	<parameter name="inbound.http.port">8085</parameter>
<sequence xmlns="" name="TestIn">
    <send receive="reciveSeq">
            <address uri="http://localhost:9000/services/SimpleStockQuoteService"/>
<sequence xmlns="" name="reciveSeq">

This configuration file synapse_sample_902.xml is available in the <ESB_HOME>/repository/samples directory.

To build the sample

  1. Start the ESB with the sample 902 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.

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, to execute the Stock Quote Client in the Dumb Client Mode.

    ant stockquote -Dtrpurl=http://localhost:8085/

Analyzing the output

Analyze the output debug messages for the actions in the dumb client mode.

You will see that the ESB receives a message when the ESB Inbound is set as the ultimate receiver. You will also see the response from the back end in the client.
