SOAP over JMS protocol

• The client must use a javax.jms.BytesMessage object or a javax.jms.TextMessage object to transmit the SOAP request message to the server.
• The client must set the following properties on the JMS request message before sending the message to the destination queue or topic:
  • SOAPJMS_contentType: This property is similar to the Content-Type header found in an HTTP message and is used to describe the content type of the message. A text-only SOAP message, for example, a message with no attachments, has the following value set for this JMS message property:

    text/xml; charset="UTF-8"

    For a SOAP message containing attachments, use the following code to set the SOAPJMS_contentType property on the JMS message:

    multipart/related; type="text/xml"; start="<...content-id_of_first_ part...>" 

    This example represents a multipart message, where the first part is of type text/xml and contains the SOAP envelope. The other parts of the multipart message contain various attachments. The HTTP 1.1 specification contains more information about the Content-Type header.
  • enableTransaction: Set this optional property to true on an outbound JMS request message if you want the server component to process the web service request under the same transaction that was used to receive the message from the destination queue or topic. This property is an IBM extension to the SOAP over JMS specification.
    Best practice: For client components, only set this property to true for one-way or two-way asynchronous requests to avoid synchronization problems that can occur with two-way synchronous web service requests. If this property is not set or is set to the default value of false, the server suspends the transaction that was used to receive the request message from the destination queue or topic prior to invoking the web services engine to process the request.
  • SOAPJMS_requestURI: You must set this property to the JMS endpoint URL associated with the request.
  • SOAPJMS_soapAction: This optional property is set on an outbound JMS request message to indicate the soapAction value associated with the web services request. This property is similar to the SOAPAction HTTP header used when transporting web service requests over an HTTP transport. The value of the soapAction property is a URI identifying the intent of the SOAP request. If the SOAPJMS_soapAction property is specified, it is used by the server component to determine the target of the request. The SOAP specification places no restrictions on the format or specificity of the URI nor does the specification require that the URI is resolvable. Typically, this property is set to the soapAction value from the WSDL document.
  • SOAPJMS_targetService: You must set this property on an outbound JMS request message, and the value must match the targetService property value that is found in the JMS endpoint URL for the request. This value is used by the server component to determine the port component to which the request is dispatched.
  • SOAPJMS_bindingVersion: This property indicates the version number of the protocol used by the client and server. Set the value to 1.0.
• If the request message represents a two-way request, meaning that a reply is expected, the client component must set the JMS message JMSReplyTo property to specify the queue that is used for the reply message. The JMS message setJMSReplyTo method is used to specify the queue. You can benefit from configuring a permanent reply queue on the client to prevent the client from having to create a temporary queue each time a web service request is made. Read about configuring a permanent reply queue for web services using SOAP over JMS to learn more about creating this special queue.
• If the SOAP request message represents a one-way request, meaning that a reply message is not expected, the client component must not set the JMS message JMSReplyTo property.
• The client component can assume that a reply message is a JMS BytesMessage object.
• The client component can assume that the reply message correlation ID matches the message ID of the original request message.

• The server component can expect to receive a JMS BytesMessage. If something other than a BytesMessage is received by the server component, then a fault with the subcode, unsupportedJMSMessageFormat, is returned to the client if a reply is expected.
• The server component can expect to receive a javax.jms.BytesMessage object or a javax.jms.TextMessage object. If something other than a BytesMessage or TextMessage is received by the server component, then a fault with the subcode, unsupportedJMSMessageFormat, is returned to the client if a reply is expected.
• The server component must process the SOAP request properly to produce an appropriate SOAP reply message.
• The server component must send a reply message back to the client only if the JMS request message's JMSReplyTo property is set. The JMS message getJMSReplyTo method is used to retrieve the JMSReplyTo property value from the JMS message. This property value indicates the reply destination.
• When sending a reply message, the server component must use the same message type as the request. If the request was received as a BytesMessage, the reply must be sent as a BytesMessage. Similarly, if the request was received as a TextMessage, the reply must be sent as a TextMessage.
• The server component must set the following properties in the JMS reply message before sending the message to the reply queue:
  • SOAPJMS_contentType: This property is used to describe the content type of the message. See the description for this property in the client responsibilities section in this topic.
  • correlation ID: Set the correlation ID property of the JMS reply message to the message ID of the original JMS request message. This correlation is done by calling the JMS message setJMSCorrelationID method.
  • SOAPJMS_bindingVersion: This property indicates the version number of the protocol used by the client and server. Set the value to 1.0.
