This sample demonstrates the basic functionality of a message store.
For a list of prerequisites, see Prerequisites to Start the ESB Samples.
Building the sample
The XML configuration for this sample is as follows:
<!-- Introduction to the Synapse Message Store --> <definitions xmlns="http://ws.apache.org/ns/synapse"> <sequence name="fault"> <log level="full"> <property name="MESSAGE" value="Executing default 'fault' sequence"/> <property name="ERROR_CODE" expression="get-property('ERROR_CODE')"/> <property name="ERROR_MESSAGE" expression="get-property('ERROR_MESSAGE')"/> </log> <drop/> </sequence> <sequence name="onStoreSequence"> <log> <property name="On-Store" value="Storing message"/> </log> </sequence> <sequence name="main"> <in> <log level="full"/> <property name="FORCE_SC_ACCEPTED" value="true" scope="axis2"/> <store messageStore="MyStore" sequence="onStoreSequence"/> </in> <description>The main sequence for the message mediation</description> </sequence> <messageStore name="MyStore"/> </definitions>
This configuration file

To build the sample
Start the ESB with the sample 700 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.
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
ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/ -Dmode=placeorder
Analyzing the output
When you execute the client you will see that the message is dispatched to the main sequence.
In the main sequence, the store mediator will store the
placeorder request message in the
MyStore message store. Before storing the request, the message store mediator will invoke the
Analyze the output debug messages and you will see the following log:
INFO - LogMediator To: http://localhost:9000/services/SimpleStockQuoteService, WSAction: urn:placeOrder, SOAPAction: urn:placeOrder, ReplyTo: http://www.w3.org/2005/08/addressing/none, MessageID: urn:uuid:54f0e7c6-7b43-437c-837e-a825d819688c, Direction: request, On-Store = Storing message
You can then use the JMX view of the Synapse message store by using the jconsole in order to view the stored messages and delete them.
