Why java Soft has declared HttpServlet Class as an Abstract class?Is there any performance issue?
In HttpServlet class there is no any abstract method although javasoft declared this class as an abstract class.Ok,this is valid in java.So if we want to utilize this class we will have to extends this class.But we can use to achieve this one by using Httpservlet class as simple java class also.
