If u want to initialize ur servlet to some default values ,while loading, u can use getInitParameter or similar methods found in ServletConfig. thats why u r initializing that. it is useful to establish Database connections.

init() method is the first method which gets executed first so it is always better to place code here which u want to be executed first.database connections are such things

Hi,
A servlet extends HttpServlet, which extends GenericServlet.
If you write a method called init(ServletConfig sc), you override the old method, and lose the work it was doing. By calling super.init(sc) you take advantage of it, and it's not you problem anymore to write code to properly init all the servlet.
