To reset session bean

FacesContext

.getCurrentInstance()

.getApplication()

.createValueBinding( "#{yourBeanName}").setValue(FacesContext.getCurrentInstance(), null );

To get session bean reference

Object obj = FacesContext

.getCurrentInstance()

.getApplication()

.createValueBinding("#{yourBeanName}")

.getValue(FacesContext.getCurrentInstance());

 

YourSessionBean bean = (YourSessionBean)obj;

Have you ever saw an exception with L padded before a exception???

like .executeQuery(Ljava/lang/String;)Ljava/sql/ResultSet  while running an application in your application server ?

It means that this method cannot be found on server.

The solution is to restart the server...

Here is a way to get HttpSession...

import javax.faces.context.FacesContext;
// …..
public void addInSession() {
MySession mySession = new MySession();
mySession.setName(getMsg());
/* .getSession(bool), true if we want to create new session, if want to
use old
session then false
*/
FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(false);
session.setAttribute(”sessionObj”, mySession);
if (session.getAttribute(”sessionObj”) != null) {
MySession mySavedSession = (MySession) session.getAttribute(”sessionObj”);
System.out.println(”HTTP Session: ” + mySavedSession.getName());
} else {
// do something
}
}
