After invalidating a session, you generally ask the browser to redirect to another page. The following is an example to redirect back the same page.

<button label="c" onClick="session.invalidate(); Executions.sendRedirect(null);"/>

I couldn't post the example.. if the session is invalidated then we should restart the server. If else, we would not be able to get a valid session.

thx.

Here is the code that I test the session invalidation.

1. enter "ABC" in session value textbox.
2. push "save into session"
3. push "fetch from session and show on the label", and it show "ABC".
4. push "invalidate session" and the page load.
5. push "fetch from session and show on the label" and nothing shown.

Everything is as expected. I am not sure what's wrong with your case.

<window id="main" title="hello" border="normal" width="300px"> Session value:
<textbox id="txuser"/>
<label id="lbuser"/>

<button label="save into session" onClick="session.setAttribute("user",
txuser.getValue())"/>
<button label="fetch from session and show on the label"
onClick="lbuser.setValue(session.getAttribute("user"))"/>
<button label="clear the label" onClick="lbuser.setValue(null);"/>
<button label="invalidate session" onClick="session.invalidate(); Executions.sendRedirect(null);"/> </window>

Hi Henry, thx for the helpful example. I did trace my code and found where's the error.. I put the session into static, and forgot to invoke getcurrentsession..
so it's always invalidated.

thx a lot and sorry for that henry.. don't be tired to help us :)
