Basics of Servlet

[pcvardhan]

When does the init() method of the servlet get called:-
When first equest comes to the servlet or when it get deplolyed.

[javarishi]

It depends on the Configuration which we did in the web.xml.

If we put load on startup tag inside web.xml and if we mention the

particular servlet inside this tag, at the time of server startup, web -

container will load the servlet class into the memory, and webcontainer

will create the servlet instance by calling the default

constructor. After that container will initialize this servlet by calling init()

method. So All initialization code we can put inside init tag inside the

web.xml, get the ServletConfig Object. These properties of the servlet


will be shared among the clieants.
