Is this a feature or bug in Axis?

[Jin Voon <Ji...@orderware.net>]

Hi all,

I'm writing a simple web service in Axis to test RPC  web service calls 
with different parameter modes.
I have this web service method:

public int addIntegerAllModes(int inParam, IntHolder outParam, IntHolder 
inOutParam)
{
        int numberToAdd = 10;
        outParam.value = inParam + numberToAdd;
        inOutParam.value = inOutParam.value + numberToAdd;
        return 123;
 }

As you can see, i'm passing in parameters which uses all three modes - IN, 
OUT and INOUT

The deployment descriptor is:

<operation name="addIntegerAllModes">
      <parameter name="inParam" mode="IN" />
      <parameter name="outParam" mode="OUT" />
      <parameter name="inOutParam" mode="INOUT" />
 </operation>

I'm calling this using DII, and only pass in parameter values for the IN 
and INOUT parameters, with the values 6 and 2 respectively.  The soap 
request message generated is:

<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>
  <ns1:addIntegerAllModes 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:ns1="http://orderware.net/junit">
   <inParam xsi:type="xsd:int">6</inParam>
   <inOutParam xsi:type="xsd:int">2</inOutParam>
  </ns1:addIntegerAllModes>
 </soapenv:Body>
</soapenv:Envelope>

As you can see, this message is correct.  However, the soap response I got 
is:

<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>
  <ns1:addIntegerAllModesResponse 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
xmlns:ns1="http://orderware.net/junit">
   <addIntegerAllModesReturn 
xsi:type="xsd:int">123</addIntegerAllModesReturn>
   <inOutParam xsi:type="xsd:int">16</inOutParam>
   <outParam xsi:type="xsd:int">10</outParam>
  </ns1:addIntegerAllModesResponse>
 </soapenv:Body>
</soapenv:Envelope>

As you can see, the result is WRONG!  The outParam should be 16 and the 
inOutParam should be 12, according to the addIntegerAllModes() method.
Seems to me like it's confused the value assignment i.e.

inParam = 6
outParam = 2
inOutParam = 0

instead of

inParam = 6
outParam = 0 (not set in the invoke)
inOutParam = 2

Is this an Axis bug? At this point I'm thinking it is.....but I might be 
wrong.  Thanks for any help!

Jin
