Hi all: I've started cleaning up the "message style" service architecture for Axis, and wanted to run some thoughts by the assembled masses for comments.
As I see it, there are three cases we want to support. NOTE: In all of these cases, I think that there's the "give me the envelope" option and the "give me the body contents" option. This is simply specifying your method as taking a SOAPEnvelope or a SOAPBodyElement[], i.e.: public SOAPBodyElement [] envMethod(SOAPEnvelope env); public SOAPBodyElement [] bodyMethod(SOAPBodyElement [] bodies); The engine will figure out the right thing to do based on the method signature (during OperationDesc introspection). Now, here are the cases (each containing sample WSDD): 1) Single method handling all messages. <service name="singleMethod" style="message"> <operation name="envMethod"/> (or equiv <allowedMethods>) </service> In this case, any message which comes in would pass the whole envelope to envMethod(). 2) Element localName "automaps" to method name <service name="automap" style="message"> <allowedMethods>bodyMethod envMethod</allowedMethods> (or equiv <operation>s) </service> So in this case, <Body><bodyMethod>...</bodyMethod></Body> would end up calling bodyMethod() with the body elements, and <Body><envMethod>...</envMethod></Body> would call envMethod() with the whole envelope. Other XML would result in "no such method". 3) Arbitrary mapping of element QName -> method <service name="mapped" style="message"> <operation name="method1" qname="ns:someElement" xmlns:ns="http://foo"/> <operation name="method2" qname="ns:otherElement" xmlns:ns="http://foo"/> </service> In this case, bodyMethod() would get called when a message arrived which looks like: <Body> <foo:someElement xmlns:foo="http://foo";>...</foo:someElement> </Body> In a similar way, foo:otherElement would call envMethod, and other elements would get "unrecognized element". Note that this approach makes the following assumption - if there is a single <operation> or allowed method, we should funnel ALL messages to it. If there is more than one, we should do a mapping (either the default localname one, or a specific one). It may be that there is a case where you have a single method that you want to accept a single body QName and fault on others - if so, we'd need to define another way of doing that (i.e. an "acceptAll" attribute on the <operation> to indicate the non-matching case). QUESTIONS: Are these the right options? Does the suggested WSDD make sense? Thanks for your input! --Glen
