アプリケーションの実行に問題があります。私はサーバーを持っています:
#include "Hello_impl.h"
#include <iostream>
#include <omniORB4/CORBA.h>
#include <omniORB4/Naming.hh>
using namespace std;
int main(int argc, char ** argv)
{
try {
// init ORB
CORBA::ORB_ptr orb = CORBA::ORB_init(argc, argv);
// init POA
CORBA::Object_var poa_obj = orb->resolve_initial_references("RootPOA");
PortableServer::POA_var poa = PortableServer::POA::_narrow(poa_obj);
PortableServer::POAManager_var manager = poa->the_POAManager();
// create service
Hello_impl * service = new Hello_impl;
// register within the naming service
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("TestServer");
name[0].kind = CORBA::string_dup("");
nc->rebind(name, service->_this());
cout << "Server is running ..." << endl;
}
} catch (CosNaming::NamingContext::NotFound &) {
cerr << "not found" << endl;
} catch (CosNaming::NamingContext::InvalidName &) {
cerr << "invalid name" << endl;
} catch (CosNaming::NamingContext::CannotProceed &) {
cerr << "cannot proceed" << endl;
}
// run
manager->activate();
orb->run();
// clean up
delete service;
// quit
orb->destroy();
} catch (CORBA::UNKNOWN) {
cerr << "unknown exception" << endl;
} catch (CORBA::SystemException &) {
cerr << "system exception" << endl;
}
}
およびクライアント:
import java.util.*;
public class client {
public static void main(String [] args) {
org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args, null);
if (orb == null) System.exit(-1);
try {
// obtain service from naming server
org.omg.CORBA.Object ns_obj = orb.resolve_initial_references("NameService");
org.omg.CosNaming.NamingContext nc
= org.omg.CosNaming.NamingContextHelper.narrow(ns_obj);
org.omg.CosNaming.NameComponent [] path
= { new org.omg.CosNaming.NameComponent("TestServer", "") };
org.omg.CORBA.Object obj = nc.resolve(path);
Hello hello = HelloHelper.narrow(obj);
// use service
String server = hello.say_hello("Hello, omniORB C++ server, it's Java client");
System.out.println("Answer from server: " + server);
// destroy
orb.destroy();
} catch (org.omg.CORBA.ORBPackage.InvalidName exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CosNaming.NamingContextPackage.NotFound exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CosNaming.NamingContextPackage.CannotProceed exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CosNaming.NamingContextPackage.InvalidName exception) {
exception.printStackTrace(System.out);
} catch (org.omg.CORBA.COMM_FAILURE exception) {
exception.printStackTrace(System.out);
} catch (Exception exception) {
exception.printStackTrace(System.out);
}
}
}
次のように omniNames を開始します。
omniNames -start 6666 -logdir /home/mazix/Desktop/example/logs -errlog /home/mazix/Desktop/example/logs/omniNamesError.txt
次に、次のようにサーバーを起動します。
./server -ORBInitRef NameService=IOR: .... (and here is my IOR num)
そして、クライアントを(同じコンピューター上で)起動します:次のように:
java client -ORBInitRef NameService=corbaloc::localhost:6666/NameService
そして、それは機能していますが、次のようにサーバーを起動したい(する必要があります):
./server NameService=corbaname::localhost:6666
とクリネ:
java client -ORBInitialHost localhost -ORBInitialPort 6666
しかし、そのように開始すると機能しません:/
何か助けはありますか?:(
ここに私の omniORB 構成ファイルがあります: http://www.2shared.com/document/dBAhFGLh/omniORB4cfg.html
それに加えて、サーバーが私のコンピューターにあり、クライアントが私の学校のコンピューターにある場合、問題が発生します。彼らはお互いを「見ていない」:(
わかりました: omniNamesを開始していませんが、omniNames を開始する前に何かがポート 2809 でリッスンしていました。
私はそれで大丈夫だと思ったので、端末に「omniNames」と入力してomniNamesを実行する必要はなく、実行しませんでした
あなたが言ったようにサーバーを実行しようとしただけです:http://i46.tinypic.com/2q2e33c.png
私はこれを試しました:
- omniNames を実行しました: omniNames -start 6666
- サーバーを実行しました: ./server -ORBInitRef NameService=corbaloc::localhost:6666/NameService -ORBtraceLevel 40
そしてこれを得ました:
mazix@computer:~/Desktop/example/cpp$ ./server -ORBInitRef NameService=corbaloc::localhost:6666/NameServie -ORBtraceLevel 40
