Access jsp pages in WEB-INF directory

Question

Hi,
I've a problem with my jsp web project;
practically I've created a web project that uses jsp pages and servlet.
I never use links to jsp pages, directly in my web pages, but I call always first servlet;
the servlet call jsp pages.
My project is completed and works fine, but any user can access to my jsp pages directly simply writing the url.
So I've tried to move my jsp pages in the WEB-INF directory, but now I doesn't manage in accessing index.jsp page;
how must I do to access index.jsp page?
I've tried to modify web.xml like this
<welcome-file-list>
          <welcome-file>WEB-INF/index.jsp</welcome-file>
     </welcome-file-list>
but doesn't work;
besides also servlet calls to jsp pages doesn't work anymore.
How can I solve?
Thank you in advance

ok, so first you have to implement the Filter interface, with 3 methods,
the main method u have to put logic in is doFilter()
public class YourClass implements javax.servlet.Filter {
doFilter(ServletRequest req, ServletResponse res, FIlterChain chain) throws ... {
//check first if is HTTP, if in this case permission is not granted as well
if(req instanceof HttpServletRequest{
HttpServletRequest httpReq = (HttpServletRequest)req;
//now check if its called for index.jsp
if(!httpReq.getRequestURI().toLowerCase().endsWith("index.jsp"))
   throw new ServletException("access permitted");
else
  chain.doFilter(req,res); //go on with processing
}else
throw new ServletException("only HTTP requests allowed");
}and of course you have to register that filter in your web.xml doing
  <filter>
    <filter-name>yourFilter</filter-name>
<filter-class>yourFilterClass</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>yourFilter</filter-name>
    <url-pattern>/**.jsp</url-pattern>
  </filter-mapping>actually that's it
