Accessing EJB 3.1 from the client using the JNDI on port no 3700 glashfish Server

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_______________________

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

For connectivity problems at the client side, we normally don't require looking at the server-side code. Please edit your question and leave out only the relevant information. — Isaac, Nov 23 '12 at 01:41

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:

has this changed much since javaee5 to now javaee7, or, pretty much the same? – Thufir Oct 11 '14 at 23:43
