Dear Ranchers

Happy New year!!

I am in the process of developing a JSP Web application, with frame sets and iframes. The purpose of using the frame set and iframe is the page remains same throughout the application (egs: Header, left panel menu, footer) and the content part will the only one changing.

Now, I have in my web.xml, I have the session time out set to 10 minutes.



My challenge, if I left the web page idle for more than 10 minutes, the session is getting invalidate and when I come back and click any link in the left menu/content page, the iframe or content frameset is only giving the session time out message and not the whole page.

Please give me an idea to resolve this.

Thanks/Regards

Aravind Prasad

You can use HttpSessionListener which listens to session creation and session destruction events. Redirection to specific JSP can be added in sessionDestroyed(HttpSessionEvent event) method [ this method receives a notification whenever a session is destroyed]. Here JSP will be your main JSP which contains all Header,. footer, left panel etc.

Another technique is mentioned in this URL

Framesets are long considered dinosaurs. There are better ways to achieve common templating across pages (SPA, Tiles, etc). I'd advise you to modernize your approach.
 
It is sorta covered in the JavaRanch Style Guide.
