Cannot store reference to a stateful session bean in the HTTP session
---------------------------------------------------------------------

                 Key: JBAS-9198
                 URL: https://issues.jboss.org/browse/JBAS-9198
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Web (Tomcat) service
    Affects Versions: 7.0.0.Beta1
            Reporter: Andrig Miller
            Assignee: Remy Maucherat
             Fix For: 7.0.0.Beta2


I have ported an application from AS 5/EAP 5.1 to AS 7 (a snapshot of Beta 2 actually), and in that application I am looking up a reference to a stateful session bean, to store it in the HTTP session, and the actual storage of the reference, gets the following:

javax.servlet.ServletException: java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute sfsbOrderInquiry
	services.web.OrderInquiryServlet.doGet(OrderInquiryServlet.java:78)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:734)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

root cause

java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute sfsbOrderInquiry
	org.apache.catalina.session.StandardSession.setAttribute(StandardSession.java:1289)
	org.apache.catalina.session.StandardSession.setAttribute(StandardSession.java:1250)
	org.apache.catalina.session.StandardSessionFacade.setAttribute(StandardSessionFacade.java:130)
	services.web.OrderInquiryServlet.doGet(OrderInquiryServlet.java:74)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:734)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

It's saying that my attribute is not serializable, but the OrderInquiryBean in the lookup implements Serializable.

The code in the servlet is as such, and it fails on the session.setAttribute("sfsbOrderInquiry", orderInquiry):

HttpSession session = request.getSession();

		OrderInquiry orderInquiry = (OrderInquiry) session.getAttribute("sfsbOrderInquiry");

		if (orderInquiry == null) {

			InitialContext context = null;

			try {
				context = new InitialContext();
				orderInquiry = (OrderInquiry) context.lookup("java:app/OrderManagerEJB/OrderInquiryBean!services.ejb.OrderInquiry");
				session.setAttribute("sfsbOrderInquiry", orderInquiry);
			} catch(Exception lookupError) {
				logger.log(Level.ERROR, lookupError.getStackTrace().toString());
				response.setStatus(500);
				throw new ServletException(lookupError);
			}

		}

The top of OrderInquireBean looks like:

@Stateful
public class OrderInquiryBean implements OrderInquiry, Serializable {
   
   
   /** The serialVersionUID */
   private static final long serialVersionUID = -9113338082170911949L
