<BEAN> tag problem

[Franck.Allimant@alcatel.fr]

Does anybody succeed with <bean> tag ?

I'm experiencing a strange problem with GnuJSP and this bean tag, when
I'm trying to use it in a whole session (e.g., in several JSP pages).
Say, I have 2 pages (login.jsp and enter.jsp). 

In login.jsp, I'm creating a bean named dba :

   <bean name="dba" type="DatabaseAccess" scope="session"></bean>

In enter.jsp, there is :

  <bean name="dba" type="DatabaseAccess" create="no"></bean>

as I hope to use the DB connection established in login.jsp.
When enter.jsp is processed, I have the following message :

   500 JSP run-time error

   The JSP page you requested could not be served because the following
   error(s) occured:

   Could not access bean dba of type DatabaseAccess

just if the "dba" object was not stored in the session context...
But if I remove the <bean> tag from enter.jsp, and write instead :

   DatabaseAccess dba = 
       (DatabaseAccess) request.getSession(true).getValue("dba");

(hacked after a look at GnuJSP generated code), I have
the instance of DatabaseAccess, and I cant use it !
    
Any clue, somebody ?
