I followed your advise and implemented a filter to retrieve the SFSB-proxy once
the HTTP-session is created:
public void doFilter(ServletRequest request, ServletResponse response,
| FilterChain chain) throws IOException, ServletException
{
|
| HttpSession session =
((HttpServletRequest)request).getSession();
| ShopTree shopTree;
| if (session.isNew()) {
| try {
| Context context = new InitialContext();
| shopTree = (ShopTree)
context.lookup("app/ShopTreeBean/local");
| } catch (NamingException e) {
| throw new ServletException(e);
| }
| session.setAttribute("shopTreeBean", shopTree);
| }
| chain.doFilter(request, response);
| }
I verified that the filter is working as expected.
But the result of the endeavor is just as before. Not surprisingly I can pick
up the proxy (local IF) from the session in my ImageServlet successfully.
But once I try to access a method, at the first time Seam is complaining like
this:
Caused by: org.jboss.seam.RequiredException: @In attribute requires non-null
value: shopTree.applicationUser
|
However, I have verified that the field applicationUser is available in the
Seam context. Moreover, I have debugged the Seam action-method which is
implemented in the same SFSB and verified that the field has already been
populated on a previous request.
At the second request to the ImageServlet, I am getting
javax.ejb.NoSuchEJBException: Could not find stateful bean:
a4i810-vbn2mr-f8u25ljn-1-f8u49lh5-12
My only explanation is that JBoss' JNDI-implementation delivers a serialized
instance (copy) of the original instance that is available in the
EJB-container. However, AFAIK, this would not fit with the JBoss'
specification, which says that JNDI-lookups for local IF's (in the same VM)
result in a reference to the instance, not in a serialized copy.
Anymore hint for me?
