Setting application attribute

[Joseph Sweet]

Hi Friends,

I need to set some application attribute in the very beginning whenever tomcat is being restarted.

Where should i put the code to be executed???

somthing like:

  
 
getServletContext().setAttribute("totalUserNum",long_num_i_have_just_found_from_the_app_database);
 

any ideas?

Thanks, Joseph

That's what context listeners are for:

You can put that application scope variable
on init method of oyur controller servlet.That is the sevlet ewhich load on start up as 1.

Prior to the advent of context listeners, a load-on-startup servlet was frequently used to perform application-wide initialization, but a context listener is a much better way to do it now that they are available.

It is guarenteed that all context listeners are executed before any servlets are loaded or executed.
