  • And why do you want that? JSP is a preprocessor for HTML. When browser requests a `.jsp` file, tomcat generates valid, static HTML from the templating rules. When browser requests a `.html` file, it is served as it is. Do you want your URLs to have a `.html` extension instead of `.jsp`? – Jesvin Jose Feb 13 '12 at 05:54
  • yes i want url extension to be .html – jan5 Feb 13 '12 at 05:55
  • Then you need URL rewriting. The only way I can (yes, there could be simpler ways) think of is putting Apache as a reverse proxy (mod_proxy) **in front of** Tomcat and implementing URL rewrite rules (mod_rewrite) to rename `.jsp` to `.html` – Jesvin Jose Feb 13 '12 at 06:25
  • thank u aitchnya i added jsp *.html in web.xml and it worked fine – jan5 Feb 13 '12 at 06:42
  • So there **was** a simpler method :-) – Jesvin Jose Feb 13 '12 at 08:47
  • @jan5 A blackbox pen-tester sees .jsp and .do and knows the server is tomcat. You're doing their job for them by not masking this in some way. – Nielsvh Feb 20 '15 at 16:20

add 

         <servlet-mapping> <servlet-name>jsp</servlet-name>
         <url-pattern>*.html</url-pattern>
          </servlet-mapping>

in web.xml

The accepted answer didn't work for me. I did get something working for a specific html page though (index.html)

  <servlet>
    <servlet-name>IndexServlet</servlet-name>
    <jsp-file>/index.jsp</jsp-file>
  </servlet>
  <servlet-mapping>
    <servlet-name>IndexServlet</servlet-name>
    <url-pattern>/index.html</url-pattern>
  </servlet-mapping>
