Session scoped managed bean not available as session attribute in filter

After following the JSF HTTP Session Login tutorial, i tried clicking on pages and it redirected me always to the login page (without css). I tried debugging using the code below:

Enumeration<String> attributeNames = wrappedRequest.getSession().getAttributeNames();
    while(attributeNames.hasMoreElements()) {
                System.out.println(attributeNames.nextElement());
    }

and found that the class I expected to be return at 

ConnectionManager manager = (ConnectionManager) wrappedRequest.getSession()
            .getAttribute("connectionManager");

wasn't returned. Some other class was returned instead of ConnectionManager class as seen in the server log. 

Info:   employeeManager
Info:   org.jboss.weld.context.beanstore.http.LockStore
Info:   com.sun.faces.renderkit.ServerSideStateHelper.LogicalViewMap
Info:   org.jboss.weld.context.conversation.ConversationIdGenerator
Info:   org.jboss.weld.context.ConversationContext.conversations
Info:   javax.faces.request.charset

EmployeeManager is another managed bean. Can I know why this is return instead?

Solution

  • That answer was based on the ConnectionManager being a JSF managed bean. However, based on presence of CDI-specific objects in the session, it looks like that you're using CDI @Named instead of JSF @ManagedBean to manage beans (which is at its own a Good Thing though).

    You could just @Inject it into the filter instead of manually grabbing it from the HTTP session.

    @Inject
private ConnectionManager connectionManager;
