발생 원인 : javax.naming.NamingException

Question

두 개의 프로젝트가 있습니다. 첫 번째는 Ejb3 프로젝트이며 이름은 SessionBean이고 Java 프로젝트는 SessionBeanClient입니다. IDE의 경우 일식 인디고를 사용합니다. 나는 코드를 완성하고 컴파일 할 때 오류가 발생한다. 다음은 오류입니다. 세션 빈

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(); 
    } 

} 

를 들어 인터페이스

enter code here 
package com.iqbal.interfaces; 

import javax.ejb.Remote; 

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

과 이미 빌드 경로에서 SessionBeanClient에 세션빈 프로젝트를 추가하고 추가해야

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(); 
     } 
    } 
}

appserv- rt.jar 및 gf-client.jar 및 glassfish 서버 라이브러리. 하지만 .. 위의 오류가 여전히 나옵니다. 누구든지 도울 수있어, 제발 ...?

Answer 1

저는 요즘은 similar problem이었습니다 (적어도 관련이 있다고 생각합니다). 몇 가지 조사를 한 후에 잘못된 구성의 RMI 포트를 사용하고 있다는 것을 알았습니다. 8080을 사용했지만 제 경우에는 서블릿 포트 (8080)가 RMI 포트 (제 경우는 JBoss 1099가 기본 포트)와 동일하지 않은 것으로 보입니다.

Answer 2

나는 이미 포트 8080을 3700으로 바꾼다. 왜?, 왜냐하면 8080은 로컬이기 때문에 인터페이스에 @Remote를 설정했기 때문에 3700을 사용해야했다. 틀렸어, 말해줘.
