nadir amra closed AXISCPP-1048.
-------------------------------

       Resolution: Fixed
    Fix Version/s: current (nightly)

Actually the problem was in the generated TestServicePortTypeWrapper.cpp code.   The original code generated invalid code as follows:

		xsd__int ret = pWs->add(v0,v1);
		return pIWSSZ->addOutputParam("return", (void*)&ret, XSD_INT);

The corrected code looks like the following:

		xsd__int * ret = pWs->add(v0,v1);
		return pIWSSZ->addOutputParam("return", (void*)ret, XSD_INT);


The reason pointers are used is because you have minOccurs="0" in element definitions.

> 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 :-)
