Delay in starting HASingletonDeployer EJB binding
Hi,
I have written timer using HASingletonDeployer type=Barrier. Below is code for that
@Stateless(name="GenerationEJBTimer")
@Depends("jboss.ha:service=HASingletonDeployer,type=Barrier")
@LocalBinding(jndiBinding=ISiteRegenerationTimer.EJB_JNDI)
@TransactionManagement(TransactionManagementType.BEAN)
@Interceptors(SpringBeanAutowiringInterceptor.class)
public class GenerationEJBTimer implements IRegenerationTimer {
/**
* Start the EJB Timer
*/
public void startTimer() {
LOGGER.debug("SiteGenerationEJBTimer : START TIMER");
// Check if any instances of the Timer already exists. If so kill it!!!
//timer start code
}
...
and Interface is
@Local
public interface IRegenerationTimer {
public final static String EJB_JNDI = "ejb/local/RegenerationTimer";
public static final String TIMER_NAME = "REGENERATION_TIMER";
public final Long FIVE_MINUTES = 1000L*60L*5L;
public void startTimer();
public void stopTimer();
}
and I have written servlet listener which will call GenerationEJBTimer through JNDI lookup.
public class InitializeRegenerationTimer implements ServletContextListener {
public void contextInitialized(ServletContextEvent aSce) {
LOGGER.info("Initializing InitializeRegenerationTimerContext : START");
try {
this.getRegenerationEJBTimer().startTimer();
} catch (NamingException e) {
LOGGER.error("ERROR: Unable to locate RegenerationEJBTimer...", e);
}
LOGGER.info("Initializing InitializeRegenerationTimerContext : STOP");
}
private IRegenerationTimer getRegenerationEJBTimer() throws NamingException
{
InitialContext ctx = new InitialContext();
return (ISiteRegenerationTimer)ctx.lookup(IRegenerationTimer.EJB_JNDI);
}
and this will be declared in web.xml as below
<listener> <listener-class>com.web.servlet.InitializeRegenerationTimer</listener-class> </listener>
Now when I deploy this in Jboss 4.2.1.GA cluster server, I am getting javax.naming.NameNotFoundException: ejb not bound at exception even though EJB is deployed before the web app.
when I looked at the logs EJB is starting before web app starts but binding is happening after web app starts. Because of that InitializeRegenerationTimer.getRegenerationEJBTimer() is throwing ejb not bound at exception error.
Please help me how to overcome this problem.
thanks in advance.
