Hi,
At first, sorry for my English and my low knowledge in EJB and RMI.
I’m new to EJB technologies but I’d like to use them for further
projects. So I tried to execute a classical hello world scenario involving an
application client and an EJB module. The application client access remotely
to my EJB module using injection (@EJB) and I distribute this client to end
user using java web start.
*My issue:*
When I launch the client from browser on the glassfish host, all is working:
my client access the EJB module and send me back the good result.
When I launch the client from browser on another local network’s computer,
I can download the client, I got the validation for execution screen, but
after that nothing’s happen. The javaw corresponding thread is still in
thread’s pool and I can wait lot of time without any change. So no error
message on client neither in glassfish logs.
When I launch another application client without distant EJB connection it
works fine on distant computer.
*My sources*
*Remote interface*
[code]
import javax.ejb.Remote;
@Remote
public interface ServiceBeanRemote {
String service1();
String service2();
}[/code]
*EJB module*
[code]import javax.ejb.Stateless;
@Stateless
public class ServiceBean implements ServiceBeanRemote {
@Override
public String service1() {
return "service 1";
}
@Override
public String service2() {
return "service 2";
}
}
[/code]
*Application client that bug on distant computers*
[code]//... several imports
import javax.ejb.EJB;
import service.ServiceBeanRemote;
public class Main {
@EJB
private static ServiceBeanRemote serviceBean;
public static void main(String[] args) {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(new JTextField(serviceBean.service1()),
BorderLayout.CENTER);
f.setSize(400,400);
f.setVisible(true);
}
}[/code]
*Application client that works*
[code]import javax.swing.JOptionPane;
public class Main {
public static void main(String[] args) {
JOptionPane.showMessageDialog(null, "Hi dude !");
}
}[/code]
*My environment : *
Server one: windows 7 32bits – netbeans 7.1 + glassfish 3.1.1 – java 7 u2
Server two: windows 7 64bits – netbeans 7.1 + glassfish 3.1.1 – java 6
u25
Client 1 : windows 7 64bits – java 7 u2
Client 2 : windows XP 32bits – java 7 u2
I shut down all firewalls on my computers, and I tried on 2 differents
clients. I set two glassfish servers on two differents systems and I get the
same issue.
