EJB 3873 Can not get connection to server
I got a frustrated problem when I try to call more than two method in same remote interface from client, sometimes it run correctlly and give me right answer but 90% will get a Exception listed bellow. I tryed likely hundreds times and figure out that if I only call one method at a time , it work fine. but if I
call two method closely it will throw this Exception...hep thanks.
public static void main(String[] args)
{
InitialContext ctx;
try
{
ctx = new javax.naming.InitialContext();
ctx.addToEnvironment(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
ctx.addToEnvironment(Context.PROVIDER_URL, "jnp://localhost");
ctx.addToEnvironment("InitialContext.SECURITY_PRINCIPAL", "user");
ctx.addToEnvironment("InitialContext.SECURITY_CREDENTIALS", "password");
ctx.addToEnvironment("java.naming.factory.url.pkgs", "org.jboss.naming");
HelloWorldRemote remote = (HelloWorldRemote)ctx.lookup("HelloWorld/remote");
System.out.println(remote.sayHello("ken"));
System.out.println("res =" + remote.getRes());
System.out.println("res + 10 = " + remote.add(10));
System.out.println("res =" + remote.getRes());
System.out.println("res + 20 = " + remote.add(20));
System.out.println("res =" + remote.getRes());
ctx.close();
}
catch (NamingException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
it will keep giving me Exception :
