原因：javax.naming.NamingException

私は2つのプロジェクトを持っています最初はEjb3プロジェクトの名前はSessionBeanで、JavaプロジェクトはSessionBeanClientです。 IDEの場合は、日食インディゴを使用します。私はコードを完了し、私はコンパイルしたときにエラーが発生します。ここにエラーがあります。セッションBean原因：javax.naming.NamingException

enter code here 

package com.iqbal.ejb; 

import javax.ejb.Stateless; 

import com.iqbal.interfaces.ISessionFacade1Local; 

@Stateless(name="SessionFacade1", mappedName="SessionFacade1") 
public class SessionFacade1 implements ISessionFacade1Local 
{ 

    @Override 
    public double generatedRandomNumber(int number) 
    { 
     // TODO Auto-generated method stub 
     return Math.random(); 
    } 

}

するためのインタフェース

enter code here 
package com.iqbal.interfaces; 

import javax.ejb.Remote; 

@Remote 
public interface ISessionFacade1Local 
{ 
    public double generatedRandomNumber(int number); 
}

のためにそして、私はすでにビルドパスからSessionBeanClientにSessionBeanのプロジェクトを追加し、追加する必要があり

enter code here 
package com.iqbal.client; 
import java.util.Properties; 

import javax.naming.InitialContext; 
import javax.naming.NamingException; 

import com.iqbal.interfaces.ISessionFacade1Local; 


public class BeanClient 
{ 
    public static void main(String[] args) 
    { 
      Properties props = new Properties(); 

      props.setProperty("java.naming.factory.initial", 
          "com.sun.enterprise.naming.SerialInitContextFactory"); 

      props.setProperty("java.naming.factory.url.pkgs", 
          "com.sun.enterprise.naming"); 

      props.setProperty("java.naming.factory.state", 
          "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl"); 


      // optional. Defaults to localhost. Only needed if web server is running 
      // on a different host than the appserver 
      props.setProperty("org.omg.CORBA.ORBInitialHost", "localhost"); 

      // optional. Defaults to 3700. Only needed if target orb port is not 3700. 
      props.setProperty("org.omg.CORBA.ORBInitialPort", "8080"); 

      try 
      { 
      InitialContext ic = new InitialContext(props); 
      ISessionFacade1Local local = (ISessionFacade1Local)ic.lookup("SessionFacade1#com.iqbal.interfaces.ISessionFacade1Local"); 

      System.out.println("Random Number is== "+local.generatedRandomNumber(200)); 
      } 
      catch (NamingException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 
}

私は最近、similar problemを持っていました（少なくとも私は適切だと思います）。何らかの調査の後、自分の設定で間違ったRMIポートを使用していることがわかりました。私は8080を使用しましたが、私の場合、サーブレットポート（8080）はRMIポートと同じではないように見えました（JBoss 1099ではデフォルトポートです）。

私はすでにポート8080を3700に変更しています。なぜですか？なぜなら、ローカル用の8080であり、インターフェイスで@Remoteを設定しているからです。3700を使用しなければなりません。間違って、教えてください。

ポート8080は、GlassfishのデフォルトのポートHTTP（Webサイト、Webサービス）です。ポート3700は、リモートEJBを呼び出すために使用されるCORBA ORB（IIOPプロトコル経由）のデフォルトポートです。 –
