Hello

I set timeout for RWT session
RWT.getUISession().getHttpSession().setMaxInactiveInterval(timeout * 60 * 60);

How to catch expire timeout and put warning message to user?
Dmitry

Hi,

There is no way to notify the user - no connection is active (and non has been for your timeout period), that is the reason the session expired in the first place.

What I did for a high-user-page was to let the clients poll every few minutes (~3minutes), and set a short timeout(6 minutes):

		int pollingTimeoutMS = 6*3600*1000; //stop keeping the session alive after 6hours
			RWT.getUISession().getHttpSession().setMaxInactiveInterval(180);
			String code =   ""
					+ "var pollStart = Date.now();"
					+ "window.setInterval( function() {\n"
					+ "     if((pollStart + " + pollingTimeoutMS + ") > Date.now()) {" 
		               + "     rwt.remote.Connection.getInstance().send();\n"
		               + "  }"
		               + "}, 150000 );";		
			 JavaScriptExecutor executor = RWT.getClient().getService( JavaScriptExecutor.class );
			 if( executor != null ) {
			     executor.execute( code );
			 }	


This will cost a tiny little bit of CPU and bandwidth, however with the benefit of freeing sessions rather aggressivly without impacting the user experience.

Think I was wrong.
Command "MaxInactiveInterva"lsets timeout for inactive session but my application has thread for auto-update widgets and setMaxInactiveInterval does not help me check users' activity. It's permanent session!. Isn't it?

p.s. I can catch event SWT.Selection for buttons, list and etc and update last time real user' actiivty
