        // TODO Auto-generated method stub

    }                 

}

I'm accessing the user.html(which has form) using http://localhost:8080/User/user.html. where User is the folder name which contains the html and servlet program.

The url pattern defined as <url-pattern>/LoginServlet</url-pattern> in web.xml for the servlet

Hi,

One concern u r extending the HttpServlet class so u need not to implement Servlet interface again as because HttpServlet class is implementing the Servlet interface.

Regards,
Sateesh.

So the output of

Expand|Select|Wrap|Line Numbers

 
System.out.println("name is:" +name);

System.out.println("password is:" +password);

is

Expand|Select|Wrap|Line Numbers

 
name is:

password is:

(Without adding the values for name and password.) Is that correct? Or do you get no output at all?

Your form submit method is "post" but you have overriden the doGet method.

Note that if you override the service method instead, then your code will be executed whether the form uses get or post.

Sorry as i was busy i have'nt checked your reply.

in the reply #9 it's mentioned like "Your form submit method is "post" but you have overriden the doGet method.
Note that if you override the service method instead, then your code will be executed whether the form uses get or post." by you. So i have modified my code and checked but even then when i submit the form with values they are not getting displayed in the console nor in the html page.

I also asked you to post the changes you've made. Did you rebuild the application after those changes?
Also make sure that your servlet path is correct.
