Difference between Session Expired and ViewExpiredException

I've come across many solutions for the two 'huge' problems

  • Session Expired
  • ViewExpiredException

My Question: What is the difference between them?

I'm using WAS and I observed

  • Restarting the EAR in the console does not cause the session to expire
  • If there is a current ajax request and the EAR is restarted it throws ViewExpiredException but does not logout the user
  • If the page is idle for, say 30 min, the login screen appears (I've used a sessiontimeoutfilter to handle this)

So isnt ViewExpiredException same as Session Expiry? Also why doesnt restarting the EAR cause the session to expire?

Any help would be appreciated.

restarting doesnt kill the session as it is persisted by your app server by way of serialization. - Mark W

Setting javax.faces.STATE_SAVING_METHOD to client will solve the problem. Also using an ExceptionHandler and NoCacheFilter will solved the problem

I prefered the latter, since it is more maintainable.
