Description

The stub generated by

java -classpath %lib%\..\axis\wsdl2ws.jar;%axis% org.apache.axis.wsdl.wsdl2ws.WSDL2Ws %wsdl% -o./ClientOut -lc++ -sclient

has a defect. In a debug win32 build, this results in the Microsoft runtime stopping the a client with a failed assertion

/*

• If this ASSERT fails, a bad pointer has been passed in. It may be
• totally bogus, or it may have been allocated from another heap.
• The pointer MUST come from the 'local' heap.
  */
  _ASSERTE(_CrtIsValidHeapPointer(pUserData));

the call stack at the point of failure is

_free_dbg(void *, int)
free(void *)
operator delete(void *)
Calculator::add(int, int)
main(int, char * *)

The Calculator::add(int, int) function is declared in the generated stub Calculator.cpp. This function is shown below. The line that reads

delete Ret;

seems to be the problem.

/Methods corresponding to the web service methods/

/*

• This method wrap the service method add

  xsd_int Calculator::add(xsdint Value0, xsd_int Value1)
  {
  xsd__int* Ret = NULL;
  const char* pcCmplxFaultName;
  try
  {
  if (AXIS_SUCCESS != m_pCall->initialize(CPP_RPC_PROVIDER))
  return *Ret;
  if (NULL==m_pCall->getTransportProperty("SOAPAction",false)) { m_pCall->setTransportProperty(SOAPACTION_HEADER , ""); }

  return r;
  }
