Call servlet On Server Startup

How can i call a function automatically when the server started ?

From where you want to call the function or which event do you want to perform?
Ask a question which is clear to understood .

I don't think this is a JavaScript question unless you want to call this servlet from the client-side (in which case, you would use Ajax).

What server software is it? Even Java/JSP wouldn't be enough. You will need some server setting (I think Tomcat has this ability) to trigger this, or you could poll the server using a page on another server.

u can implement the ServletContextListener interface in a java class
to access 2 methods namely,
and
from the parameter e you can access the context and write whatever code u wish to execute within the first of the two methods i mentioned.

and one more thing
add this code to your web.xml config file

<listener>
<listener-class>mypackage.myclass</listener-class>
</listener>

Moved to the Java forum. If someone feels it doesn't belong here, please move to a more appropriate forum, thanks.

A Servlet is bound to a certain application (or more of them) but a server has
to deal with all of them. There is no reason for a server to call a method from a
particular Servlet. Check your server documentation if it can handle callbacks
when it starts up.
