Since you are in wrapped/literal mode shouldn't the encoding style be
""? Or you could try using <beanMapping> rather than
<typeMapping>. Also, the <msgT> tag looks strange. It
seems unnecessary but if you do add then I think you need a
deserializer for that structure too.

 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.<o:p></o:p>
 <o:p> </o:p>
 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:<o:p></o:p>

 <o:p> </o:p>
 My web service class’
relevant method signature (this
is a java rpc service):<o:p></o:p>
 public BalanceDueMsgType
getBalanceDue(BalanceDueMsgType
msgT)<o:p></o:p>
 <o:p> </o:p>
 I am using JDK 1.4.2,
JBoss 3.2.5/JBoss.Net/Axis 1.1 <o:p></o:p>
 <o:p> </o:p>
 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:<o:p></o:p>
 org.xml.sax.SAXException:
SimpleDeserializer encountered a
child element, <o:p></o:p>
 which is NOT expected, in
something it was trying to
deserialize.<o:p></o:p>
 <o:p> </o:p>
 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:<o:p></o:p>

 context=

 <o:p> </o:p>
 <o:p> </o:p>
 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.<o:p></o:p>
 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):<o:p></o:p>
 <BalanceDueMsg
xmlns=<a class="moz-txt-link-rfc2396E" href="http://balancedue.websvc.csp.leapwireless.com">"http://balancedue.websvc.csp.leapwireless.com"</a>><o:p></o:p>
 
<accountNum>ACCOUNTNUMBER</accountNum><o:p></o:p>
 
<sessionId>STRING</sessionId><o:p></o:p>
 
<balanceData/><o:p></o:p>
 
</BalanceDueMsg><o:p></o:p>
 <o:p> </o:p>
 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.<o:p></o:p>
