http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16574 java.lang.NullPointerException in classes that implement HttpSessionBindingListener Summary: java.lang.NullPointerException in classes that implement HttpSessionBindingListener Product: Tomcat 4 Version: 4.1.18 Platform: Other OS/Version: Windows NT/2K Status: UNCONFIRMED Severity: Normal Priority: Other Component: Servlet & JSP API AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The problem is, that when replace a session attribute that implements HttpSessionBindingListener, in the valueUnbound method I get java.lang.NullPointerException. example: public void valueUnbound(HttpSessionBindingEvent be) { User u = (User)be.getValue(); System.out.println("The user " + u.getName() + " was unbounded"); } I believe that the error is that in line 1250 of StandardSession (new HttpSessionBindingEvent((HttpSession) this, name)); you have put (new HttpSessionBindingEvent((HttpSession) this, name, unbound)); In the specification of Servlet 2.3, the method getValue() of HttpSessionBindingEvent class say: .... If the attribute was replaced, this is the old value of the attribute. Thank for your attention and sorry for my english. I you don't understand me, please let me know. Jorge L. Middleton Bs. As.
