Hi all!

I have some doubts about init method in servlet initialization.

1. if init method is not overridden the which version of init method is called by Container?
init() or init(ServletConfig)

2. when init() version of init method is overridden then how Container get ServletConfig object for that servlet?

Thaks...

1. if init method is not overridden the which version of init method is called by Container?
init() or init(ServletConfig)

The Container will call the init(ServletConfig) method.
Because The Servlet interface is having only one method init(ServletConfig) there is no method such that init() in Servlet Interface.
If we see the init() method is provided in GenericServlet Interface . Even we override this method it will be called by init(ServletConfig) method. This method is provided for the UserConvienence.


2.when init() version of init method is overridden then how Container get ServletConfig object for that servlet?
Even we overridden the init() method the container will get the ServletConfig object through getServletConfig()

Discussions are always welcomed

Hi abhijeet,
Intially the webcontainer checks init(ServletConfig) in your class(Ex: MyServlet), if it is not found(i.e.,overridden), it checks in the GenericServlet class(GenericServlet class implements init(ServletConfig)of Servlet interface).

Finally, init(ServletConfig) will be called if you are not overriding it in MyServlet class and in init(ServletConfig) method of GenericServlet class
init() method will be called.

if we override init(ServletConfig) then we need to use super.init(config) to get the ServletConfig.

if we override init() then we dont require to user any super.init(config)
