Subject Custom Deserializer/typeMapping problem
Date Thu, 17 Feb 2005 17:25:15 GMT
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:

>From my dd:

    <typeMapping qname="baldue:BalanceDueMsg"







My web service class' relevant method signature (this is a java rpc

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

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= ""

namespace= ""

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

<BalanceDueMsg xmlns="">






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:

























            <faultstring>org.xml.sax.SAXException: SimpleDeserializer

                encountered a child element, which is NOT expected, in

                it was trying to deserialize.</faultstring>
