Dear all,

Can anybody explain me the difference between init(ServletConfig config)
method and init() method.
API says simply override no arg init() method which will be called by
init(ServletConfig config) method? What do you mean by this?

Kindly explain.....................


regards,
Amit Kulkarni

Hi,

GenericServletClass implements ServletConfig and Servlet Interface.

the default behavior of GenericServlet class is when init() is invoked it calls init(ServletConfig) this class now has reference of ServletConfig from Servlet Container.
the extending class has to call getServletConfig() to get reference of Config from container.

getServletConfig() method call can be avoided /Extending class can obtain ServletConfig reference by calling super.init(ServletConfig).

Hope this clarifies your doubt.

the basic difference I know,

init(ServletConfig) is called by the servlet container to indicate to a servlet that the servlet is being placed into service.

init() is the method you override for doing some stuff at the time of initialization. init() method is called by GenericServlet.init(ServletConfig)
