IllegalArgumentException for BigInteger

[Markus Schulz <ma...@m-schulz.net>]

I have a WSDL file from a customer and generated Java code from it with 
WSDL2Java.

There are some classes generated that contain a value of type 
BigInteger. One of them is described in the WSDL-file as follows:

            <xsd:complexType name="LifecycleStateDTO">
                <xsd:sequence>
                    <xsd:element name="stateCode" type="xsd:integer"/>
                </xsd:sequence>
            </xsd:complexType>

So xsd:integer seems to be mapped to BigInteger in java code. When I 
call a method, that returns this type (LifecycleStateDTO - directly or 
nested), i get an IllegalArgumentException. I traced the communication 
with Wireshark and saw that the server returned valid data, so the 
exception is thrown on client-side. Does the client not understand the 
xsd:integer to BigInteger mapping? Is there any way for me to enforce it?
I tried to change the java code manually, and replaced BigInteger with
int. With these changes made, everything works fine. But I don't like 
that solution, since the webservice interface (and so the WSDL file) is 
changed frequently, so I have to regenerate the java code from time to 
time. That would mean a lot of manual BigInteger->int conversion each 
time the interface changes. Is there maybe some way of telling WSDL2Java 
to generate int from xsd:integer?

I've been searching the web for solutions for hours now... can somebody 
please help me with that?
