Hi all,
I'm programming in C++/Qt. Today I intend to use C++/Qt just to
client and Java to server using glassfish and DB PostgreSQL.
This example(1) in java (client and server), it's working.
I'm searching a solution to mix this two technologies(C++/Qt and
Java server).
I did a bean class to return a little message(java)
Ex 1: server
package br.com.cadastro;
import java.util.List;
import javax.ejb.Stateless;
/**
*
* @author juaci
*/
@Stateless
public class CadastroBean implements CadastroRemote, CadastroLocal {
public String getName() {
return "<<<<<<<<<< My first test..... >>>>>>>>>>>>>>>>";
}
}
Ex 2: client C++/Qt
1 - How can I pass the parameter using this command line to test this
code below?
Command line: ./cliente corbaname:iiop:localhost:3700/NameService
2 - The name of package in java is "br.com.cadastro.CadastroRemote".
I would like adjust the command line above calling my package and
to fix this piece of code below.
CosNaming::Name name;
name.length(1);
name[0].id = CORBA::string_dup("CadastroRemote");
// name[0].id = CORBA::string_dup("br.com.cadastro.CadastroRemote");
name[0].kind = CORBA::string_dup("");
#include "CadastroRemote.h"
#include <iostream>
#include <CORBA.h>
#include <Naming.hh>
using namespace std;
int main(int argc, char ** argv)
{
try {
// init ORB
CORBA::ORB_ptr orb = CORBA::ORB_init(argc, argv);
// resolve service
CadastroRemote_ptr cadastro = 0;
try {
CORBA::Object_var ns_obj =
orb->resolve_initial_references("NameService");
if (!CORBA::is_nil(ns_obj)) {
CosNaming::NamingContext_ptr nc =
CosNaming::NamingContext::_narrow(ns_obj);
CosNaming::Name name;
name.length(1);
name[0].id = CORBA::string_dup("CadastroRemote");
// name[0].id =
CORBA::string_dup("br.com.estante.cadastro.CadastroRemote");
name[0].kind = CORBA::string_dup("");
CORBA::Object_ptr obj = nc->resolve(name);
if (!CORBA::is_nil(obj)) {
cadastro = CadastroRemote::_narrow(obj);
}
}
} catch (CosNaming::NamingContext::NotFound &) {
cerr << "not found" << endl;
} catch (CosNaming::NamingContext::InvalidName &) {
cerr << "invalid name" << endl;
} catch (CosNaming::NamingContext::CannotProceed &) {
cerr << "cannot proceed" << endl;
}
if (!CORBA::is_nil(cadastro)) {
char * server = cadastro->getNome();
cout << "answer from: " << server << endl;
CORBA::string_free(server);
}
// destroy ORB
orb->destroy();
} catch (CORBA::UNKNOWN) {}
}
// EOF
If I made a mistake with codes please correct me.
Someone has another better idea I appreciate your help.
Thanks.
