Container creates an instance of the servlet when you have started/deployed the application.and not at the time you made a request.

[writetokaruna@yahoo.com]

This tag specifies that the servlet should be loaded automatically when the web application is started.
The value is a single positive integer, which specifies the loading order. Servlets with lower values are loaded before servlets with higher values (ie: a servlet with a load-on-startup value of 1 or 5 is loaded before a servlet with a value of 10 or 20).
When loaded, the init() method of the servlet is called. Therefore this tag provides a good way to do the following:

• start any daemon threads, such as a server listening on a TCP/IP port, or a background maintenance thread
• perform initialisation of the application, such as parsing a settings file which provides data to other servlets/JSPs

If no value is specified, the servlet will be loaded when the container decides it needs to be loaded - typically on it's first access. This is suitable for servlets that don't need to perform special initialisation.

So if u give zero low priority will be given.


comments r welcome.

hi swathi
The webcontainer is the responsible for calling the init() before creating the object. but when u r providing the webcontainer first creates the object in the browser after thn it will call the init() metod.
