Question

Many times whenever I try to access some pages or click buttons "Could not find stateful bean: 3j011-udy7sm-hkt798pd-1-hkt7bobh-9"error hits on the screen for the JSF project.Do anybody know the cause for this errpr

Answer 1

Possibly you ran into a timeout, and the stateful session been has been removed by the container.

You can use @StatefulTimeout (EJB 3.1) to set this value. A quote from the Javadoc:

Specifies the amount of time a stateful session bean can be idle (not receive any client invocations) before it is eligible for removal by the container.

To verify if that is really the case, add a method with @PreDestroy, so you can see if the SFSB has been removed.

Example:

@Stateful(name = "xxx")
@StatefulTimeout(value = 15, unit = TimeUnit.SECONDS)
public class Sfsb {
  @PreDestroy
  public void preDestroy() {
    System.out.println("INFO: " + "@PreDestroy");
  }
}
