Error in InitialContext lookingup

Question

IDE: Netbeans 8.0.
Server ejb:
"@Stateless
public class ejb implements ejbRemote{
    public String say(){
    return "hello";
}"                                    //Server ejb is located in the host: 192.168.0.2 , project ER/ejb-ejb/beans/
Interface ejbRemote:
"@Remote
public interface  ejbRemote{
public String say();
}"                                      // Interface ejbRemote is located in the eLibary.jar file in package sessionLibary , both included in Server project ER and Web project.
Web jsp useBean:                                // located on another host: 192.168.0.3
"public class ws{
     ejbRemote eb= lookupejbRemote();
     private ejbRemote lookupejbRemote(){
       try{
           Properties p = new Proterties();
            p.setProperty(Context.PROVIDER_URL,"t3://192.168.0.2:7676");
           Context c=new InitialContext(p);
           //return (ejbRemote)c.lookup("java:global/ER/ejb-ejb/ejb!s.ejbRemote")     //  ERROR: Root Exception: ER not found.
           //return ((ejbRemote)c.lookup(ejbRemote.class.getName());    //ERROR: Root Exception:  sessionLibary.ejbRemote not found.
        }catch (NamingException ne){}
     public String wsay(){
      return eb.say();
When I run the Web project on the Server host, it's OK. But when I run it on another host it returns error. I can access 192.168.0.2:7676 in browser(returns some context string), so it may not be caused by firewall.
I think the problem is the initalContext is not generated from 192.168.0.2:7676 but from local JVM, because when when running it in the Server I change the ip address to random number it also is OK.
I am a newbie in java EE. It is really hard for me to solve by myself. Please help!

I have no idea what you are doing, but the code you posted doesn't even compile. You help nobody by posting code that "looks like" what you have, if you want help post the exact code you're using. The only thing you should mask is sensitive information such as a username/password and a global IP address.
Also consider this: why do you think it is important to mention the IDE you're using (it really is not) yet you completely hide which JEE container you're using.
Your JEE container should have a management interface which can tell you under which JNDI names your EJBs are deployed; use that information to know what the proper lookup name is to use in your client code.
