Prerequisites

Start ESB with the following sample configuration:

Code Block
languagehtml/xml
linenumberstrue
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://ws.apache.org/ns/synapse">
    <!-- the SimpleURLRegistry allows access to a URL based registry (e.g. file:/// or http://) -->
    <registry provider="org.apache.synapse.registry.url.SimpleURLRegistry">
        <!-- the root property of the simple URL registry helps resolve a resource URL as root + key -->
        <parameter name="root">file:repository/conf/sample/resources/</parameter>
        <!-- all resources loaded from the URL registry would be cached for this number of milli seconds -->
        <parameter name="cachableDuration">15000</parameter>
    </registry>
    <sequence name="main" onError="errorHandler">
        <in>
            <property name="OUT_ONLY" value="true" />
            <property name="FORCE_SC_ACCEPTED" scope="axis2" value="true" />
        <!--Dynamic Reclipient List-->
            <send>
                <endpoint>
                    <recipientlist>
                        <endpoints value="{get-property('registry','recipients/EP_LIST')}"/>
                    </recipientlist>
                </endpoint>
            </send>
            <drop/>
        </in>
    </sequence>
    <sequence name="errorHandler">
        <makefault response="true">
            <code xmlns:tns="http://www.w3.org/2003/05/soap-envelope" value="tns:Receiver"/>
            <reason value="COULDN'T SEND THE MESSAGE TO THE SERVER."/>

        <send/>
    </sequence>
</definitions>

Deploy the SimpleStockQuoteService and start three instances of sample Axis2 server as mentioned in sample 52 Sessionless Load Balancing Between 3 Endpoints.

To test this, run the stockquote client to send an out-only message as follows:

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