Many message transformation scenarios require a new outgoing message to be built. The Create Message Class template in the JavaCompute node wizard generates template code for this.
MbMessage outMessage = new MbMessage();The headers can be copied from the incoming message using the supplied utility method, copyMessageHeaders(), as shown in this Java code:
copyMessageHeaders(inMessage, outMessage);The new message body can now be created. First, add the top level parser element. For XML, this is:
MbElement outRoot = outMessage.getRootElement(); MbElement outBody = outRoot.createElementAsLastChild("XMLNSC");The remainder of the message can then be built up using the createElement methods and the extended syntax of the broker XPath implementation.
