Hi,
If you see the implementation of service method ,there your request will be forwarded to either doGet , doPost ,doPut ....based on the httpMethod.
So if you override the service method programmer should take care to forward the request to appropriate doXXX methods.
just have a look at this url to know about the implementation of service method...
http://www.docjar.com/html/api/javax/servlet/http/HttpServlet.java.html why do you want to override service method..?If you are developing webapp then doXXX methods will do process your requests.
