Sample 264: Sending Two-Way Messages Using JMS transport
Note that WSO2 EI is shipped with the following changes to what is mentioned in this documentation:
<PRODUCT_HOME>/
repository/samples/
directory that includes all Integration profile samples is changed to<EI_HOME>/
samples/service-bus/
.<PRODUCT_HOME>/

Objective: Demonstrate sending request response scenario with JMS transport
<definitions xmlns="http://ws.apache.org/ns/synapse"> <proxy xmlns="http://ws.apache.org/ns/synapse" name="StockQuoteProxy" transports="http"> <target> <endpoint> <address uri="jms:/SimpleStockQuoteService?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory& java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory& java.naming.provider.url=tcp://localhost:61616&transport.jms.DestinationType=queue"/> </endpoint> <inSequence> <property action="set" name="transport.jms.ContentTypeProperty" value="Content-Type" scope="axis2"/> </inSequence> <outSequence> <property action="remove" name="TRANSPORT_HEADERS" scope="axis2"/> <send/> </outSequence> </target> <publishWSDL uri="file:repository/conf/sample/resources/proxy/sample_proxy_1.wsdl"/> </proxy> </definitions>
Prerequisites:
- You need to set up ESB and axis2 server to use the JMS transport. See Sample 251 for more details.
- Create the above configuration and deploy it in the WSO2 EI profile, see Working with WSO2 Integration Studio.
This sample is similar to Sample 251. Only difference is we are expecting a response from the server. JMS transport uses transport.jms.ContentTypeProperty to determine the content type of the response message. If this property is not set JMS transport treats the incoming message as plain text.
In the out path we remove the message context property TRANSPORT_HEADERS. If this property is not removed JMS headers will be passed to the client.
Start ESB using sample 264.
Start Axis2 server with SimpleStockService deployed.
Invoke the stockquote client using the following command.
ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy -Dsymbol=MSFT
The sample Axis2 server console will print a message indicating that it has received the request:
Generating quote for : MSFT
In the client side it should print a message indicating it has received the price.
Standard :: Stock price = $154.31851804993238
