Problem to connecte Tuxedo Service via WTC

Question

Hello,
I'm new to WTC. I want to call a tuxedo service disposed in our serveur tuxedo by using WTC.
I created Local APs, Remote APs and Imported for this Tuxedo Service.
When I call I have always same erreur (perrno = 6) in tpcall
See below my calling webservice method
Have any one guide to avoid this problem?
Any help will be greatly appreaciated.
Thanks
@WebMethod
public void getClientInfo() {
     Context ctx;
     TuxedoConnection myTux;
     TypedString dataIn = new TypedString("1, 10032600");
     //TypedBuffer dataIn = null;
     Reply rpy = null;
     try{          
          System.out.println("getClientInfo called : " + dataIn);
          TuxedoConnectionFactory tcf;               
          ctx = new InitialContext();
          tcf = (TuxedoConnectionFactory) ctx.lookup("tuxedo.services.TuxedoConnection");
          myTux = tcf.getTuxedoConnection();          
          System.out.println("About to call tpcall cnx = "+myTux);
          rpy = myTux.tpcall("LireInfoClient_SE",null, 1);
          System.out.println("tpcall successfull!");
          dataIn = (TypedString) rpy.getReplyBuffer();          
          myTux.tpterm(); // Closing the association with Tuxedo
          System.out.println("Return = "+dataIn.toString());
     }catch (TPReplyException tpx) {
          // Could not get the tuxedo object, throw TPENOENT
          System.out.println("TPReplyException perrno = " + tpx.gettperrno()+" DETAILS "+tpx.gettperrordetail()+" getLocalizedMessage "+tpx.getLocalizedMessage()+" "+tpx.getCause());
          tpx.printStackTrace();
     }catch (TPException tpx1) {
          // Could not get the tuxedo object, throw TPENOENT
          System.out.println("TPReplyException perrno = " + tpx1.gettperrno()+" DETAILS "+tpx1.gettperrordetail()+" getLocalizedMessage "+tpx1.getLocalizedMessage()+" "+tpx1.getCause());
          tpx1.printStackTrace();
     }catch (NamingException ne) {
               // Could not get the tuxedo object, throw TPENOENT
               System.out.println("Could not get TuxedoConnectionFactory : " + ne.getMessage());
               ne.printStackTrace();
     }catch(Exception e){
               System.out.println("Exception in getClientInfo ->"+e.getMessage());
               e.printStackTrace();
     return;
Output :
<getClientInfo called : 1, 10032600>
<About to call tpcall cnx = weblogic.wtc.gwt.TuxedoConnection@159d713>
<TPReplyException perrno = 6 DETAILS 0 getLocalizedMessage null null>

The tpcall function only supports an input parameter, an input buffer. In the input buffer you must send all the information the service needs. If you need send some data items you can use FML buffers, strings buffers, ... By example, with strings buffers in C:
#define NAME_LEN 16
#define LASTNAME_LEN 30
#define ADDRESS_LEN 30
#define AGE_LEN 3
typedef struct {
     char name[NAME_LEN+1];
     char lastname[LASTNAME_LEN+1];
     char address[ADDRESS_LEN+1];
     char age[AGE_LEN+1];
} persondat;
Client side:
main(int argc, char *argv[])
persondat *ptrperson;
char *sendbuff = NULL;
long sendlen = 0;
MAXBUFFIN_LEN = sizeof(persondat);
if((sendbuff = (char*)tpalloc("STRING", NULL, MAXBUFFIN_LEN+1)) == (char*)NULL) {
fprintf(stderr, "Error tpalloc(%s).\n", tpstrerror(tperrno));
tpterm();
exit(1);
ptrperson = (persondat*)sendbuff;
** Fill out the information.
sprintf(sendbuff->name, "%*s", NAME_LEN, "your name");
sprintf(sendbuff->lastname, "%*s", LASTNAME_LEN, "your lastname");
sprintf(sendbuff->address, "%*s", NAME_LEN, "your address");
sprintf(sendbuff->age, "%0*d", NAME_LEN, 37);
** Service call.
ret = tpcall("ADDPERSONSVC", (char*)sendbuff, 0, (char**)&recvbuff, &recvlen, (long)0);
if(ret == -1) {
fprintf(stderr, "Error tpcall(%s).\n", tpstrerror(tperrno));
tpterm();
exit(1);
Server side:
void ADDPERSONSVC(TPSVCINFO *rqst)
persondat *ptrperson;
ptrperson = (persondat*)rqst->data;
fprintf(fout, "Name: [%s].\n", ptrperson->name);
fprintf(fout, "Last Name: [%s].\n", ptrperson->lastname);
fprintf(fout, "Address: [%s].\n", ptrperson->address);
fprintf(fout, "Age: [%d].\n", atoi(ptrperson->age));
Regards.
