Java Development Tools

Can someone help me with this TOMCAT issue:-
I am attempting to implement a logout method that will invalidate the current session and redirect to the login page (based on SRLogout demo eg).

The code works fine in JDeveloper Embedded OC4J Server, but when i deploy the application to Tomcat 5.5.9 it throws an exception that the Session has already been invalidated.

I also notice that When i print the session object in JDev it is: 'HTTP Session ac104af6231ccf2bd0e9a39148c5adc1ea2714432a9e' but in Tomcat it is : 'org.apache.catalina.session.StandardSessionFacade@bfb545'


See the method below and exception below :

public String logoutButton_action() throws IOException{
ExternalContext ectx = FacesContext.getCurrentInstance().getExternalContex();
HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
HttpSession session = (HttpSession)ectx.getSession(false);
session.invalidate();

response.sendRedirect("Login.jspx");
return null;
}



Exception
