RE: [Axis2] Axis C++ client for SAPBC

Hi!
  I've tried to create a client that sends SOAP messages to SAPBC using AXIS C++. Running my code I've received this error:
"Exception : DLOPEN FAILED in loading parser library" 
 
I've understood that this problem could appear when the axiscpp.conf is not well configured.
Firstly, in my case where this file should be located? Because in your examples you have some specifications just for Apache servers. Is this file needed for all the clients that we want to implement? 
  Secondly, I will show you how I've tried to connect to SAP BC in order to see if the bussines is OK:
 
 
InteropTestPortType::InteropTestPortType()
:Stub(" ", APTHTTP1_1)
{
 m_pCall->setEndpointURI("http://localhost:5555/soap");
}
InteropTestPortType::~InteropTestPortType()
{
}

/*Methods corresponding to the web service methods*/
/*
 * This method wrap the service method echoString
 */
xsd__string InteropTestPortType::echoString(xsd__string Value0)
{
 xsd__string Ret = NULL;
 const char* pcCmplxFaultName;
 try
 {
  if (AXIS_SUCCESS != m_pCall->initialize(CPP_RPC_PROVIDER)) 
   return Ret;
  m_pCall->setTransportProperty(SOAPACTION_HEADER , "base#echoString");
  m_pCall->setSOAPVersion(SOAP_VER_1_1);
  m_pCall->setOperation("SOAPRPCTESTCLIENT", "SCANDLOG");
  applyUserPreferences();
  m_pCall->addParameter((void*)&Value0, "xml", XSD_STRING);
  if (AXIS_SUCCESS == m_pCall->invoke())
  {
   if(AXIS_SUCCESS == m_pCall->checkMessage("hello", "SCANDLOG"))
   {
    Ret = m_pCall->getElementAsString("_return", 0);
   }
  }
 
 m_pCall->unInitialize();
  return Ret;
 }
 catch(AxisException& e)
 {
  int iExceptionCode = e.getExceptionCode();
  if(AXISC_NODE_VALUE_MISMATCH_EXCEPTION != iExceptionCode)
  {
 
 m_pCall->unInitialize();
   throw base_AxisClientException(e.what());
  }
  ISoapFault* pSoapFault = (ISoapFault*) m_pCall->checkFault("Fault","http://localhost/axis/base" );
  if(pSoapFault)
  {
 
 m_pCall->unInitialize();
   throw base_AxisClientException(pSoapFault);
  }
  else throw;
 }
}

 
//base
 
int main(int argc, char* argv[])
{
  
    try
 {
  
  InteropTestPortType ws;
  
  printf("invoking echoString...\n");
  //testing echoString 
  AxisChar* pachEchoStringResult = ws.echoString("hello world");
   printf("pachEchoStringResult\n");
  
 }
 catch(AxisException& e)
 {
  printf("Exception : %s\n", e.what());
 }
 catch(exception& e)
 {
  printf("Unknown exception has occured\n");
 }
 catch(...)
 {
  printf("Unknown exception has occured\n");
 }
 return 0;
}

Thank you,
     F.

Re: Axis C++ client for SAPBC

Hi Florin,
        AXISCPP_HOME is used to find the axiscpp.conf file that contains 
information on explicitly where to find the associated DLLs.  The problem 
is that these DLLs use other DLLs and the location of these DLLs needs to 
be on your path.  For example, AxisXMLParserXerces.dll relies on 
xerces-c_2_2_0.dll (I think it also works with other, newer versions, but 
lets not go into that now!).  If the xerces DLL is not on the path then 
AxisXMLParserXerces.dll will load then immediately unload and will to the 
user look like it has not loaded.  Infact it did load, but could not load 
the libraries that it is dependant on and so therefore immediately 
unloaded....   I hope this makes things a little clearer :-)

Regards,

Fred Preston.

OK, What version of xerces are you running (it needs to be 2.2.0)? - and 
can you cut and paste your config file her pls. 

thanks, 
John.

Re: Axis C++ client for  SAPBC








Hello! 
I've tried to execute my client AXIS C++ for SAP BC from VC6.0 and I've 
received the same execption: <Exception : DLOPEN FAILED in loading parser 
library> even I've set up the AXISCPP_HOME enviroment variable to the path 
of axiscpp.conf. Can somebody help me to pass this error? 
 Thank you! 
  Florin

axiscpp.conf file is required by the client to locate the transport and

It should be located in AXISCPP_HOME (this envioronment variable must be 
set by you)
