@Managed beans in escbed @ EJB cause Java io. NotSerializableException
•
Java
I've been banging my head with the @ viewscoped managed bean I am using the "schedule" component of the form to display some events When the user clicks a specific button, a method in the viewcopied bean is called using Ajax, but I get one at a time
What on earth did I do wrong? Any ideas?
This is my managed bean:
@ManagedBean(name = "schedule")
@ViewScoped
public class ScheduleMBean implements Serializable {
@EJB
private CongeBean congeBean;
@ManagedProperty(value = "#{sessionBean}")
private SessionMBean sessionBean;
private DefaultScheduleModel visualiseurConges = null;
public ScheduleMBean(){
}
@postconstruct
public void init() {
if(visualiseurConges == null){
visualiseurConges = new DefaultScheduleModel();
}
}
public void updateSchedule(){
visualiseurConges.addEvent(new DefaultScheduleEvent("test",new Date(),new Date() ));
}
public void setVisualiseurConges(DefaultScheduleModel visualiseurConges) {
this.visualiseurConges = visualiseurConges;
}
public DefaultScheduleModel getVisualiseurConges() {
return visualiseurConges;
}
public void setSessionBean(SessionMBean sessionBean) {
this.sessionBean = sessionBean;
}
public SessionMBean getSessionBean() {
return sessionBean;
}
}
This is full stack tracking

Thank you in advance
Solution
@The viewscoped bean is stored in an HTTP session Any object stored in an HTTP session needs to implement serializable See also JSF managed bean causing Java io. Notserializableexception during Tomcat deployment and Java io. WriteAbortedException: writing aborted; java. io. NotSerializableException.
Notserializableexception is usually self explanatory because it refers to the fully qualified name of the class to be serialized, but not because it does not implement serializable
However, in this special case, the name seems to represent an automatically generated class, which is likely to be automatically generated by the EJB container, so it is completely out of your control
I've never seen this problem before, and Google doesn't seem to have much about it Based on stacktrace, you use GlassFish V3, so I suggest publishing an issue At the same time, your best choice is to set the JSF view state to server side
Update: similar problems in myfaces indicate JSF impl specific problems using the wrong class loader during deserialization Upgrading JSF impl should solve the problem: @ EJB in @ viewscoped @ managedbean causes Java io. NotSerializableException.
