Hallo, I try to follow a very simple example for clustering (from Jamae,
Johnson: JBoss in Action)
JBoss 4.2.0.GA
On a Windows XP machine I have started two instances, node1 and node2 which are
copies of the all configuration out of the box. On node2 I use the
BindingManager. Both instances start up normally and you can tell from the
output that there are two nodes in the DefaultPartion.
I have deployed a very simple SLSB to both nodes.
import javax.ejb.Remote;
|
| @Remote
| public interface Counter {
| public void printNumber(int number);
| }
|
|
| @Stateless
| public class CounterBean implements Counter {
|
| public void printNumber(int number) {
| System.out.println(number);
|
| }
|
| }
|
| <jboss>
| <enterprise-beans>
| <session>
| <ejb-name>CounterBean</ejb-name>
| <jndi-name>CounterBean</jndi-name>
| <clustered>True</clustered>
| </session>
| </enterprise-beans>
| </jboss>
|
|
The deployment succeeds.
The client:
public class Testclient {
| public static void main(String[] args) {
| try {
| Context initialContext = new InitialContext();
| Counter counter = (Counter)
initialContext.lookup("CounterBean/remote");
| for (int i=0; i<1000; i++) {
| counter.printNumber(i);
| Thread.sleep(500);
| }
| } catch (NamingException e) {
| e.printStackTrace();
| } catch (InterruptedException e) {
| e.printStackTrace();
| }
|
| }
| }
jndi.properties:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
| java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
When I run the client a get a
javax.naming.CommunicationException: Receive timed out [Root exception is
java.net.SocketTimeoutException: Receive timed out]

I have already tried to disable my firewall and set loopback="true" in <udp ..
in cluster-service.xml.
Many thanks for any advise
