JBoss AS6: Mini (Stateful) EJB 3 Example using JBoss and Eclipse
phiboss Oct 11, 2011 9:10 AMHi
I switched to JBoss 6.1.0. I created a new JBoss 6.1.0-Server Project:
package ch.my.timer.server;
import javax.ejb.Remote;
@Remote
public interface MyTimerRemote {
void setRemainingSecs(int seconds);
float getRemainingSecs();
}
Here the implementation:
import javax.ejb.Stateful;
/**
* Session Bean implementation class MyTimer
*/
@Stateful(mappedName="/MyTimer")
public class MyTimer implements MyTimerRemote {
public MyTimer() {
this.endTimePoint = System.currentTimeMillis();
}
private long endTimePoint; // timestamp in milliseconds
@Override
public void setRemainingSecs(int seconds) {
long millis = seconds * 1000;
long now = System.currentTimeMillis();
this.endTimePoint = now + millis;
}
@Override
public float getRemainingSecs() {
long now = System.currentTimeMillis();
long diff = this.endTimePoint - now;
float secs = (float) (diff / 1000.0);
return secs;
}
}
Starting the Server I get the following messages:

It does not look as the EJB is deployed.
Starting the following Client I get the message below:
package ch.my.timer.client;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import ch.my.timer.server.*;
public class MyTimerTest {
public static void main(String[] args) {
try {
new MyTimerTest().top();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
void top() throws NamingException {
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1099");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );
InitialContext ctx = new InitialContext(env);
MyTimerRemote str = (MyTimerRemote) ctx.lookup("/MyTimer");
str.setRemainingSecs(3);
float rem = str.getRemainingSecs();
System.out.println("Remaining: " + rem);
}
}
... here comes the message, which is obvious:
javax.naming.NameNotFoundException: MyTimer not bound
at org.jnp.server.NamingServer.getBinding(NamingServer.java:771)
at org.jnp.server.NamingServer.getBinding(NamingServer.java:779)
...
What am I missing now?
