Example C applications




Hi,
As Nadir asked, here is an example of what the Calculator C sample might
look like using generated C stubs...

#include "Calculator.h"
int main(int argc, char **argv) {
  AXISCHANDLE stub;
  char *endpoint;
  char *op;
  int num1;
  int num2;

  endpoint = argv[1];
  op = argv[2];
  num1 = atoi(argv[3]);
  num2 = atoi(argv[4]);
  stub = axiscCreateCalculatorStub(endpoint);

  if (!strcmp(op,"add")) add(stub,num1,num2);
  else if (!strcmp(op,"sub")) sub(stub,num1,num2);
  else if (!strcmp(op,"mul")) mul(stub,num1,num2);
  else if (!strcmp(op,"div")) div(stub,num1,num2);

  axiscDestroyCalculatorStub(stub);
  return 0;
}

Here is an example of what the Calculator C sample might look like without
using generated C stubs...

#include <axis/client/Stub.h>
#include <axis/AxisException.h>
#include <axis/ISoapFault.h>
#include <axis/AxisUserAPI.h>

int main(int argc, char **argv) {
  AXISCHANDLE call;
  char *endpoint;
  char *op;
  int num1;
  int num2;
  char soapaction[128];
  int ret;
  char *uri = "http://localhost/axis/Calculator";
  int result = 0;

  endpoint = argv[1];
  op = argv[2];
  num1 = atoi(argv[3]);
  num2 = atoi(argv[4]);
  sprintf(soapaction,"Calculator#%s",op);

  call = axiscCreateCall(endpoint,AXISC_APTHTTP);
  ret = axiscInitialize(call, AXISC_C_RPC_PROVIDER, AXISC_NORMAL_CHANNEL);
  if (AXISC_SUCCESS != ret) {
    printf("Failed to initialize\n");
    return -1;
  }

  axiscSetTransportProperty(call, AXISC_SOAPACTION_HEADER, soapaction);
  axiscSetSOAPVersion(call, AXISC_SOAP_VER_1_1);
  axiscSetOperation(call, op, uri);
  axiscAddParameter(call, &num1, "in0", XSD_INT);
  axiscAddParameter(call, &num2, "in1", XSD_INT);

  ret = axiscInvoke(call);
  if (AXISC_SUCCESS == ret) {
    ret = axiscCheckMessage(call, "addResponse", uri);
    if (AXISC_SUCCESS == ret) {
      result = axiscGetElementAsInt(call, "addReturn", 0);
      printf("Calculator %s %d %d returned %d\n", op, num1, num2, result);
    } else printf("Failed to get result\n");
  } else printf("Failed to invoke service\n");

  axiscUninitialize(call);
  axiscDestroyCall(call);
  return 0;
}

Obviously these need comments and better error checking.

Hi Mark,
    I have a question. What is AXISCHANDLE defined to be?
Thanks,
Samisa...
