Where to put Amazon Stub classes

Hi all,
i have big problem. I'm trying to develop a web service that will do simply
a search using amazon ws, and i want acces my service from a java client. So
i put my web service jar in AXIS-HOME/WEB-INF/lib directory. But here come
the problems:
Where i have to put Amazon stub classes obtained from the amazon wsdl file?
In order to compile my java files for my web service, i create a jar with
those stub files and putted it in the windows classpath. But it seems to me
that Axis cannot see them because every time i try to acces the web service
i got a java.lang.reflect.InvocationTargetException from Axis but i can use
ut if i simply remove the amazon code. If i put that jar with the amazon
stub in the AXIS-HOME/WEB-INF/lib directory Axis cannot start.I get an error
404.
Thanks in advance,
Roberto

Uhm... perhaps you find something.
Here is my first lines of the web service:

*<wsdl:definitions targetNamespace="urn:mywebservice">*
<wsdl:message name="myHelloResponse">
<wsdl:part name="myHelloReturn" type="soapenc:string"/>
</wsdl:message>
<wsdl:message name="mySearchRequest">
<wsdl:part name="in0" type="soapenc:string"/>
</wsdl:message>
<wsdl:message name="myHelloRequest">
</wsdl:message>
<wsdl:message name="mySearchResponse">
<wsdl:part name="mySearchReturn" type="soapenc:string"/>
</wsdl:message>
<wsdl:portType name="MywebserviceInterface">
<wsdl:operation name="myHello">
<wsdl:input name="myHelloRequest" message="impl:myHelloRequest"/>
<wsdl:output name="myHelloResponse" message="impl:myHelloResponse"/>
</wsdl:operation>
<wsdl:operation name="mySearch" parameterOrder="in0">
<wsdl:input name="mySearchRequest" message="impl:mySearchRequest"/>
<wsdl:output name="mySearchResponse" message="impl:mySearchResponse"/>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="mywebserviceSoapBinding" 
type="impl:MywebserviceInterface">
<wsdlsoap:binding style="rpc" 
transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="myHello">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="myHelloRequest">
<wsdlsoap:body use="encoded" 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
namespace="urn:mywebservice"/>
</wsdl:input>
<wsdl:output name="myHelloResponse">
<wsdlsoap:body use="encoded" 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
namespace="urn:mywebservice"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="mySearch">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="mySearchRequest">
<wsdlsoap:body use="encoded" 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
namespace="urn:mywebservice"/>
</wsdl:input>
<wsdl:output name="mySearchResponse">
<wsdlsoap:body use="encoded" 
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
namespace="urn:mywebservice"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="MywebserviceInterfaceService">
<wsdl:port name="mywebservice" binding="impl:mywebserviceSoapBinding">
<wsdlsoap:address location="http://giove:8080/axis/services/mywebservice"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

Is it what you said? To package everything i followed a tutorial using 
this script:

java org.apache.axis.wsdl.Java2WSDL -o myws.wsdl 
-l"http://localhost:8080/axis/services/mywebservice" -n urn:mywebservice 
-p"mywebservice" urn:mywebservice mywebservice.MywebserviceInterface
java org.apache.axis.wsdl.WSDL2Java -o . -d Session -s -p 
mywebservice.ws myws.wsdl

Now, my problem is: where i have to put those stupid Amazon stub 
classes? In the windows classpath in order to compile the source code. 
That is sure. But where else?
Roberto
