  • Your servlet mapping is fine, can you show the error you are getting? – Prasad Kharkar Sep 20 '13 at 08:47
  • whats your error??..are you unable to load index.html page??...Is it within web or have you kept it in web-inf?..If its within web-inf your application cannot access it... – ntstha Sep 20 '13 at 08:49
  • HTTP Status 404 - /Registration/ – user2794306 Sep 20 '13 at 08:52
  • Mapping looks OK. What URL are you trying to load? Have you considered the server's port? Is there anything suspicious in server's log? – Kojotak Sep 20 '13 at 08:53
  • /Register – user2794306 Sep 20 '13 at 08:56
  • http://localhost:8080/Registration/ coming But page is not loading – user2794306 Sep 20 '13 at 08:57
  • It should be localhost:8080/Register – Kojotak Sep 20 '13 at 09:00
  • No not working still page is not laoding how to set Servlet name what servlet name can u please tell me? – user2794306 Sep 20 '13 at 09:06
  • Servlet-name (in web.xml) is used for pairing servlet declaration (implementation class) with URL patterns, which is RegisterServlet in your case (=you have already set the name). Have you checked the server logs? What servlet container are you using and how are you deploying your app? – Kojotak Sep 20 '13 at 09:15
  • Is this question from you ? http://stackoverflow.com/questions/18913395/how-registration-page-in-servlet . It looks like a duplicate, if then please remove it. – A4L Sep 20 '13 at 09:41

As per your web.xml

your index.html should be directly inside your project folder

structure should be like this

project/index.html

and your servlet class should be in inside class folder

project/WEB-INF/classes/servlet.class
