[ http://issues.apache.org/jira/browse/MUSE-155?page=comments#action_12454716 ] Vinh Nguyen commented on MUSE-155: ----------------------------------
Hi Dan, I don't have a Tomcat server debugger setup, so it's hard for me to trace the server code. What object creates the ReflectionMessageHandler? Also, what object calls ReflectionMessageHandler.toXml()? I want to trace where the "returnValueName" and "responseBodyName" values in this method are coming from, and what they are, since they are being passed to serializer.toXml(). I suspect this might pinpoint the cause of this issue a bit further. I tested an implemention of a custom serializer for another custom Car object. When my CarTypeSerializer.toXml() is called (and I assume from the default ReflectionMessageHandler), the second parameter is a QName containing the incorrect namespace: http://schemas.xmlsoap.org/wsdl/}Car The "http://schemas.xmlsoap.org/wsdl"; namespace value seems to be coming from the xmlns="http://schemas.xmlsoap.org/wsdl/"; attribute defined in the wsdl. The result is an element with everything correct except the namespace of the topmost element: --CarTypeSerializer.toXml() Printing XmlUtils.toString(response): <?xml version="1.0" encoding="UTF-8"?> <Car xmlns="http://schemas.xmlsoap.org/wsdl/"; xmlns:car="http://cisco.com/musebox/schemas/car";> <car:make xmlns:car="http://cisco.com/musebox/schemas/car";>Honda</car:make> <car:model xmlns:car="http://cisco.com/musebox/schemas/car";>Accord</car:model> <car:color xmlns:car="http://cisco.com/musebox/schemas/car";>White</car:color> </Car> The problem seems to be near where the serializer is called on the server side. This occurs after the capability method is called, and before the serialized xml result it sent to the client. So somewhere in Muse even before the data is sent thru Axis2. Hence, when CarTypeSerializer.fromXml() is called on the client side, it also runs into the same issues with the xml it receives. > xml element capability result improperly changed when passed to the client > (namespace and prefix not preserved) > --------------------------------------------------------------------------------------------------------------- > > Key: MUSE-155 > URL: http://issues.apache.org/jira/browse/MUSE-155 > Project: Muse > Issue Type: Bug > Affects Versions: 2.0.0 > Environment: Muse 2.0.0, Axis2 1.0, Apache 2.2.3, Tomcat 5.5.17, JDK > 1.5.0_08, Windows XP SP2 > Reporter: Vinh Nguyen > Assigned To: Dan Jemiolo > > Muse is improperly changing the xml result of operations that return custom > types. > For example, my code returns a custom <Box> type in an xml Element.

In doing > so, it removes both the namespace and prefix of the <Box> element. > After removing the wrapper, the <Box> element now becomes useless because it > has no namespace, even though namespaces for child elements are properly > preserved. This is why my client code is running into errors when trying to > serialize the xml element back into a javabean (XmlBean object). It tries to > find/match the original namespace of the <Box> element, but it is nowhere to > be found. > 2) In addition to Muse removing the top element's namespace, it tries to put > in a default one instead. If my wsdl file contains the attribute > xmlns="http://schemas.xmlsoap.org/wsdl/"; > (which is defined in the samples), then Muse will take this namespace and set > it as the default in the <Box> element. So my client code complains of a > namespace mismatch. (The namespace xmlns:tns="http://ws.apache.org/axis2"; is > also inserted either by Muse or Axis2, but it isn't causing problems at this > moment.) > So I think Muse should either properly preserve the xml operation results > exactly as is, or put in the correct element namespaces and not override > incorrectly. Muse does preserve notification outputs correctly, but it > doesn't seem to do so for operations. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
