Standardization Proposal for SOAP/JMS Binding

In an email to the Apache Axis developers mailing list at apache.org, Sonic's Glen Daniels has announced that IBM, Sonic, TIBCO and BEA have creates a joint proposal for a standardized SOAP/JMS binding. SOAP over JMS is one of the possible choices for Web services-based reliable messaging, relying on a reliable transport instead of a SOAP-level reliability protocol such as WS-Reliable Messaging.

In the email, Glen writes:

As some of you may know, several companies (BEA, IBM, Progress, and TIBCO) have been working on a formal set of specifications for binding SOAP to the Java Message Service API. These specs consist of a) a SOAP binding, and b) a description of the "jms:" IRI scheme which is used for addressing. The specs do NOT cover an interoperable wire-level representation which could bridge different vendors' JMS implementations - though a future version might go there. This version has been designed so that plugging in a different implementation should work seamlessly without recompiling any code; as such we define a BytesMessage encapsulation of SOAP (and MTOM), a "Content-Type" JMS header, and a few other needed parts.

Here's an example of a WSDL file following the proposed specification:


<binding name="StockQuoteSoapJMSBinding" type="tns:StockQuotePortType" xmlns:soapjms="*placeholder*">
   <wsdl11soap11:binding style="document"
        transport="http://www.example.org/2006/06/soap/bindings/JMS/"/>

   <!-- We want this binding to use a particular CF class -->
   <soapjms:connectionFactoryName>
     sample.jms.ConnectionFactory
   </soapjms:connectionFactoryName>
   <!-- Specify PERSISTENT delivery mode -->
   <soapjms:deliveryMode>2</soapjms:deliveryMode>

   <operation name="GetLastTradePrice">
     <wsdl11soap11:operation soapAction="http://example.com/GetLastTradePrice"/>
     <input>
         <wsdl11soap11:body use="literal"/>
     </input>
     <output>
         <wsdl11soap11:body use="literal"/>
      </output>
   </operation>
</binding>

<service name="StockQuoteService">
   <documentation>My first service</documentation>
   <port name="StockQuotePort" binding="tns:StockQuoteSoapBinding">
       <wsdl11soap11:address location="http://example.com/stockquote"/>
   </port>
   <port name="StockQuotePort_jms" binding="tns:StockQuoteSoapJMSBinding">
       <wsdl11soap11:address location="jms:myQueue?targetService=stockquote"/>
   </port>
</service>
