Question

Is it possible to call Bean from Jquery? My requirement is like below,

I have a JSF 1.2 based Servlet.

Am invalidating a user’s session if he is idle for some time. Am showing Jquery dialog box 1 minute before invalidating the session. A user has 2 options in the dialog box. “Yes I want to continue” will extend the session. “No I want to logout” will logout the user.

When user clicks on “No I want to logout”, I want to call bean method where I update the Database & invalidate the session.

Below is the code,

'No, Log out': function(){
 $j.idleTimeout.options.onTimeout.call($j.post('//This is where am stuck',function()

I want to call bean in $j.post so that I can do some clean up activities in my bean.

How this can be done?

You can either use just use a hidden(style="display:none") commandButton with an action pointing to a method in your bean , and call a .click() on it from jquery

something like this

<h:commandButton id="myButton" action="#{myBean.myInvalidateMethod}" style="display:none"/>

jquery

&("#myButton").click();//possible myForm prefix appear before the id so use #myForm\\:myButton selector

Or you can call servlet from your jsf page , similar to this answer Calling a Servlet from a JSP page using jQuery Ajax
