Dear community

I developed a tomcat JSP servlet which - say - instantiates a class, 
work with that class and gives some output back to the calling user in 
the browser.


My point is instantiating the class ***once*** for every requests 
coming after this instantiation. The reason is: the class loads 
several components into memory and I would like not to do this at 
every call of this JSP servlet but just once.


Where shell I put the initializing code for the "heavy" components? Is 
this possible?


Thank you very much in advance!
Fabio

Try putting an attribute inside the servlet contex in a lazy way, that 
will be in the scope of the whole application inside the same VM.E.g.:

Object grosso = getServletContext().getAttribute("GROSSO");
if (grosso == null) {
   grosso = new Grosso();
   getServletContext().setAttribute("GROSSO", grosso);
}
If you want to limit the scope to a single session, put the same as a 
session attribute.

Initialise application once

[Fabio Ricci]

Dear community

I developed a tomcat JSP servlet which - say - instantiates a class,
work with that class and gives some output back to the calling user in
the browser.

My point is instantiating the class ***once*** for every requests coming
after this instantiation. The reason is: the class loads several
components into memory and I would like not to do this at every call of
this JSP servlet but just once.

Where shell I put the initializing code for the "heavy" components? Is
this possible?

Thank you very much in advance!
Fabio
