本人正自学JEE，有个问题想请教。I found an application client directly calls
session bean remote interface without URL in the client program. I just don'
t understand why it can call from one computer to another computer (or from
one JVM to anther JVM) without URL. What is the mechanism? Or where is the
URL defined or established?
Thanks.

I guess maybe it is done by multiple computers (servers, or JVM)

Does anybody have this experiences?

发帖数: 1550 | 6 it's for sure not in your session bean.
what's your application container,
what's your application client?

发帖数: 15 | 9 I posted all codes here. Part 1 is remote insterface. Part 2 is session bean.
Part 3 is client. You can see the client directly call remote interface
without URL. The client has no xml. Thanks.
Part 1
package order.request;
import java.io.Serializable;
import java.util.Collection;
import java.util.Date;
import javax.ejb.Remote;
@Remote
public interface Request
{
void addLineItem(
Integer orderId,
String partNumber,
int revision,
int quantity);
void addPart

发帖数: 34805 | 10 If OrderClient doesn't need any parameter, what's the point of
having a method
public OrderClient(String[] args)
I suspect the point is to pass args and create an InitialContext there.
Your code can run fine only if it's inside JEE container.

发帖数: 1550 | 12 as i'd suspected, it's only the java source code,
w/o configuration...
source code is for demo only, lz needs a container
to get the details configuration set.
and the client here is an application client,
which as you said, requires a container to run as well.
again, for lz, it's container specific,
find one and read the docs.

发帖数: 15 | 13 In my example, ejb and client is in the same ear. You mean this is called
the inside JEE container? I want to modify the client in different computer
to call ejb. Do you know how to do that?
Thanks.

发帖数: 620 | 17 You need use the JNDI look up to find the register EJB bean, here is the
sample code for jboss container.
Under jboss, the JNDI port is 1099 and 1098, EJB access port is 3837. You
need make sure those port is on when your client want to remote invoke a
server under firewall
public static void init(String server) {
mServer = server;
CONTEXT_PROPERTIES = new Properties();
CONTEXT_PROPERTIES.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.Namin |
