在端口号3700 glashfish Server上使用JNDI从客户端访问EJB 3.1

Question

I am using netbeans IDE 7.1.2 and I have created an EJB 3.1 Stateless Bean and implemented remote as well as local interfaces both and deployed it to the glassfish server 3.2.1 successfully...here is the Code

__ _ __ _ __ _ __ _ __ _ __ _ ___ CaseInfo.java _ __ _ __ _ __ _ __ _ __ _ __

enter code here

package maxx;

import javax.ejb.Stateless;

@Stateless(name="CaseInfo",mappedName="CaseInfoBean")
public class CaseInfo implements CaseInfoRemote, CaseInfoLocal {

@Override
public String MyCaseMessageLocal() {
    return "Hello this is my Local message.";
}

@Override
public String MyCaseMessageRemote() {
    return "Hello this is my Remote message.Please Note that this message is comming from the remote";
}

}

__ _ __ _ __ _ __ _ __ _ __ _ CaseInfoLocal.java _ __ _ __ _ __ _ __ _ __ _ ___

package maxx;

import javax.ejb.Local;

@Local
public interface CaseInfoLocal {

String MyCaseMessageLocal();

}

__ _ __ _ __ _ __ _ __ _ __ CaseInfoRemote.java _ __ _ __ _ __ _ __ _ __ _ __

package maxx;

import javax.ejb.Remote;

@Remote
public interface CaseInfoRemote {

String MyCaseMessageRemote();

}

now i have accessed it from locally successfully and after it i have created New Project>Java EE>Application Client project which is an desktop app hare i have accessed that bean successfully by adding jar file of bean module in to its library as a client Stub here is the some code

__ _ __ _ __ _ __ _ __ _ __ _ ___ Main.java _ __ _ __ _ __ _ __ _ __ _ __ _ __

package applicationclient;

import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import maxx.CaseInfoRemote;

public class Main {


public static void main(String arg[]) {

    try {
Properties prop = new Properties();
prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
                          "com.sun.enterprise.naming.SerialInitContextFactory");
prop.setProperty("org.omg.CORBA.ORBInitialHost", "localhost");
prop.setProperty("org.omg.CORBA.ORBInitialPort", "3700"); 

        InitialContext ic = new InitialContext(prop);
        Object ref = ic.lookup("CaseInfoBean");
        CaseInfoRemote home = (CaseInfoRemote)PortableRemoteObject.narrow(ref,
                CaseInfoRemote.class);
        System.out.println(home.MyCaseMessageRemote());

    } catch(Exception e) {
        e.printStackTrace();
    }
}
}

but when I am using this client accessing code go to New Project>java>java Application and writing here the same code so the problem showing that

__ _ __ _ __ _ __ _ __ _ __ _ ____ ERROR _ __ _ __ _ __ _ __ _ __ _ __ _ __ _ _

run:

and if i am removing properties lines of code so is giving this type of ERROR

run: javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:

please tell how can i access this bean through using simple java desktop application because its no problem to using Java EE application Client but same code is giving these error

Answer 1

You are probably not following the instructions how to access remote EJB's - deployed on a GlassFish server - from standalone Java clients. It is not entirely trivial.

This should answer your question. In general, I am suspecting that what you're missing is the gf-client.jar file in your classpath. Follow the instructions and let us know:
