I ran into a problem using Apache SOAP 2.2 within WSAD (WebSphere Studio
Application Developer IDE).  To solve it the Apache SOAP jar had to appear
before WSAD's webcontainer.jar in the CLASSPATH.  There was a method
conflict that caused the null objects to deserialize to objects built with
the default constructor.  You may have a similar conflict in one of your
jar files.

dovle pretty sad to disappoint you but this is the answer that I am
reveiving
from my apache soap when an attribute has null value: (snapshot from
UtilSnoop)

<return xmlns:ns2="kns" xsi:type="ns2:test.TestSerializable">
             <testVector xmlns:ns3="http://xml.apache.org/xml-soap";
xsi:type="ns3:Vector"
                         xsi:null="true"/>
             <name xsi:type="xsd:string" xsi:null="true"/>
             <number xsi:type="xsd:int">0</number>
             <valid xmlns:ns4="http://schemas.xmlsoap.org/soap/encoding/";
                         xsi:type="ns4:Array" ns4:arrayType="xsd:boolean[]"
xsi:null="true"/>

Are you shure that you receive the xsi:nil="true" ?

I have read the Soap specification and I have found the same :

A NULL value or a default value MAY be represented by omission of the
accessor element. A NULL value MAY also be indicated by an accessor element

containing the attribute xsi:null with value '1' or possibly other
application-dependent attributes and values.  (Quoting from W3C specs for
ksoap1.1)

So what could be wrong inhere ?

Has anyone managed to send an struct object with null attribute values ? (I

believe you have but ...)
