Custom Deserializer/typeMapping problem

[Mike Cassisa]

I am having a problem getting my Deserializer to be used after registering it’s Factory with the typeMapping element in the dd.  I have tried many different combinations but regardless of what I do the SimpleDeserializer is selected.  I believe this is happening because axis is interpreting the entire message as a String instead of my desired type.   I am somewhat new to axis so any help from those of you who really understand the framework would be much appreciated.   There have been several similar threads on this with this one being the closest to my problem, however the solution needs to be on the server not the client: List:       axis-user Subject:    (resolved) RE: deserializing nested complex types From:       Mitch Gitman <mgitman () usa ! net> Date:       2002-12-06 21:36:19   From my dd:     <typeMapping qname="baldue:BalanceDueMsg"         xmlns:baldue="http://balancedue.websvc.csp.leapwireless.com"         languageSpecificType="java:com.leapwireless.csp.websvc.balancedue.BalanceDueMsgType"         serializer="com.leapwireless.csp.websvc.balancedue.axis.BalanceDueSerializerFactory"         deserializer="com.leapwireless.csp.websvc.balancedue.axis.BalanceDueDeserializerFactory"                                                                         encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>   My web service class’ relevant method signature (this is a java rpc service): public BalanceDueMsgType getBalanceDue(BalanceDueMsgType msgT)   I am using JDK 1.4.2, JBoss 3.2.5/JBoss.Net/Axis 1.1   Basically my DeserializerFactory/Deserializer never gets a chance to deal with the incoming request message (java rpc web service).  The SimpleDeserializer always gets these and returns a this error when dealing with the nested type in the message: org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize.   I set a breakpoint in the Eclipse debugger in the SimpleDeserializer onChildElement method (which throws the exception) and this is what the variables look like in that method: this= SimpleDeserializer  (id=212)             activeDeserializers= HashSet  (id=229)             attributeMap= null             cacheStringDSer= null             cacheXMLType= null             componentsReadyFlag= false             constructor= Constructor  (id=236)             defaultType= null             id= null             isEnded= false             isHref= false             isNil= false             javaType= Class (java.lang.String) (id=200)//Based on other problems like this one I believe the problem is here, i.e. axis thinks this is a string type.             myElement= null             myElements= null             myIndex= 0             propertyMap= null             targets= Vector  (id=241)             typeDesc= null             val= CharArrayWriter  (id=246)             value= null             xmlType= QName  (id=249)                         localPart= "string"                         namespaceURI= "http://www.w3.org/2001/XMLSchema" namespace= "http://balancedue.websvc.csp.leapwireless.com" localName= "BalanceDueMsg" prefix= "" attributes= NullAttributes  (id=205) context= DeserializationContextImpl  (id=213)     Most interesting here are the values of the namespace and localName local variables (which are the ones I want) and the value of the SimpleDeserializer.javaType field  which is set to a String when it should be BalanceDueMsgType. Based on the debugger variables above, the value of the curElement field inside of the context variable has this data (which is what was intended): <BalanceDueMsg xmlns="http://balancedue.websvc.csp.leapwireless.com">                     <accountNum>ACCOUNTNUMBER</accountNum>                     <sessionId>STRING</sessionId>                     <balanceData/>                 </BalanceDueMsg>   The client I am using is a little gizmo in Oxygen XML that prepares the raw xml so you can edit it manually and then sends it… so I am not using any wsdl2java stubs or anything like that.  This tool bases everything off the wsdl/schema and is more rigorous than most in terms of validation.  Also the information is getting to the correct place in the correct way with the exception of the Deserializer that is chosen.   Here is the SOAP input and response: <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">     <SOAP-ENV:Header/>     <SOAP-ENV:Body>         <oxy:getBalanceDue             xmlns:oxy="http://balancedue.websvc.csp.leapwireless.com"             SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">             <msgT>                 <BalanceDueMsg                     xmlns="http://balancedue.websvc.csp.leapwireless.com">                     <accountNum>ACCOUNTNUMBER</accountNum>                     <sessionId>STRING</sessionId>                     <balanceData/>                 </BalanceDueMsg>             </msgT>         </oxy:getBalanceDue>     </SOAP-ENV:Body> </SOAP-ENV:Envelope>   <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"     xmlns:xsd="http://www.w3.org/2001/XMLSchema"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">     <soapenv:Body>         <soapenv:Fault>             <faultcode>soapenv:Server.userException</faultcode>             <faultstring>org.xml.sax.SAXException: SimpleDeserializer                 encountered a child element, which is NOT expected, in something                 it was trying to deserialize.</faultstring>             <detail/>         </soapenv:Fault>     </soapenv:Body> </soapenv:Envelope>   Mike Cassisa Software Engineer Cricket Communications 10307 Pacific Center Court San Diego, CA 92121 858-882-6096 Office   A good solution applied with vigor now is better than a perfect solution applied ten minutes later.                             - General George S.
