Hi guys,
its the first time that i am using the axis framework with c++ (usually
i do not develop with c/c++).
I wrote a simple calculation web service with java and deployed it to
the app-server.
The following wsdl has been generated:

You can see that it is a very simple service, which provides a "int
add(int,int)" method.
I used the wsdl2ws tool to get this declaration for the "add" method:
STORAGE_CLASS_INFO xsd__int * add(xsd__int * Value0, xsd__int * Value1);
Generally i do not have a problem with pointers (tho i don't like
primitive type pointers),
but when i get an xsd__int* back from method which is always empty
(NULL) im worried :P
I found the reason in the generated class "TestServicePortType" in
method "add":
(read comments please)
...
xsd__int * pReturn = m_pCall->getElementAsInt("return", 0);
if(pReturn)
{
Ret = *pReturn; // byVal (copy) would be better.
Axis::AxisDelete( (void *) pReturn, XSD_INT); // Deletes
the memory to which "Ret" points.
}
...
I changed the datatype of variable "Ret" and the return type of the
method from "xsd__int*" to "xsd__int" and now everything works fine.
Is this a generally known bug or is there a way to tell the wsdl2ws
tool, that i dont like primitive datatype
pointers as return value?
It's also possible that i am completely wrong... so please help me :-)

Manuel
Sorry for my bad english.
