Hi Himanshu,

Thank you very much for your reply. However, the link didn't have an exact answer.

Do you have any other link to solve this out?

This code should do it.

HttpSession session = (HttpSession) FacesContext.getCurrentInstance().getExternalContext().getSession(true);

The session bean is the object. JSF doesn't use magical constructs for managed beans. Managed Beans are just ordinary POJOs that are managed by the JSF framework.

So to get the session bean in non-JSF code (such as a servlet), just use the HttpServletRequest.getSession().getAttribute("beanname"); code construct and to get the session bean in JSF code, use JSF's faces-config.xml to inject it into the bean that references the session object.

Hi guys... I rearly sufferd with getting jsf frame work handled bean object refernce. But i got the solution. Hope it will usefull to all.
To get that reference object you have to manitain the <managed-bean> as applicaton scope


public class Report {

Report report;
int count;

public void updateCount()
{
FacesContext facesContext = FacesContext.getCurrentInstance();
Application app = facesContext.getApplication();
ValueBinding vlBinding = app.createValueBinding("#{report}");
Report uObj = (Report) vlBinding.getValue(facesContext);
uObj.setCount(uObj.getCount() + 1);
}
}
