Using Topic-based Remote Registry as Subscription Manager

Objective: Demonstrate the usage of WSO2 registry as a topic based subscription manager.

Prerequisites:

Deploy the SimpleStockQuoteService in sample Axis2 server and start it on port 9000. Run the WSO2 Registry in the local machine using the port 9446 (HTTPs).
Start Synapse with the sample configuration 503 (i.e. wso2esb-samples -sn 503).

<definitions xmlns="http://ws.apache.org/ns/synapse">
     <eventSource name="SampleEventSource">
         <subscriptionManager
             class="org.wso2.carbon.eventing.impl.RemoteRegistryBasedSubscriptionManager">
             <property name="registryURL"
                 value="https://localhost:9446/registry/" />
             <property name="username" value="admin" />
             <property name="password" value="admin" />
             <property name="topicHeaderName" value="Topic" />
             <property name="topicHeaderNS"
                 value="http://apache.org/aip" />
         </subscriptionManager>
     </eventSource>

     <sequence name="PublicEventSource">
         <log level="full" />
         <eventPublisher eventSourceName="SampleEventSource" />
     </sequence>

     <proxy name="EventingProxy">
         <target inSequence="PublicEventSource" />
     </proxy>
 </definitions>

In this sample, subscriptions stored in the WSO2 Registry,

Invoke the client (Subscriber) as follows.
