- Request object
- Response object
- Passing value
- request.getParameter method
- Query String
- Deployment Descriptor
- web.xml file
- servlet and servlet-mapping tags
- Fully qualified name
- Accepting values from user
- Printing the result on page
A servlet is a Java programming language class that is used to extend the capabilities of servers that host applications accessed by means of a request-response programming model.
Although servlets can respond to any type of request, they are commonly used to extend the applications hosted by web servers. For such applications, Java Servlet technology defines HTTP-specific servlet classes.
The javax.servlet and javax.servlet.http packages provide interfaces and classes for writing servlets.
All servlets must implement the Servlet interface, which defines life-cycle methods. When implementing a generic service, you can use or extend the GenericServlet class provided with the Java Servlet API.
The HttpServlet class provides methods, such as doGet and doPost, for handling HTTP-specific services.

Hi Naveen , great tuts.. Thanks for helping us... Had a small confusion.. Coming to servlet mapping , i do not have the tags in web.xml, yet my servlet deployed properly. Also while creating the servlet, in deployment description window, i mentioned a vague path to test like "/anything/test" , but it deployed again properly.. How was that?

im trying to do the same, servlets with jsp in tomcat, but using maven aswell, i have this problem at the beginning were i couldnt get to the servlet, i tried putting the servlet and the servlet -mapping in the xml, but whe i run it on the server i got an error, then i deleted what i put in the xml, saved, and then run it normally, after it i tried to get to the servlet and it worked..., so, to make sure it worked, i put more responses on it, but i wasnt gettig the new responses, even when i did what i did in the xml, any solution?

It is an Internal Server Error. The reason for that can be your server is not yet started or not properly configured.

hi.. Navin sir.. thanks a lot for your wonderful videos. I have been following you quite a lot. But I do have some problems in mycode, just like you, I used the PrintWriter object to print the result in the browser, but for some reason, it is not printing out anything on the browser. However, it prints in the console. It didn't work even after I used the flush method. So, please help me out figure the mistakes, if i did any. Thanks and looking forward to hearing from you soon.
