How do you guys work around this trivial situation?

Question

Hi,
I'm using GlassFish v2 and JSF 1.2.
Since JSP can be run using the direct url of the JSP page and the JSF pages require some prefix like "/faces/" how do you guys deal with situations
when somebody accesses the direct link of the JSF (that means without typing "faces/") ? - I noticed that GlassFish throws an error in this case which must be addressed I think.
Any hint or constructive comment would be highly appreciated. Or is this an open problem when using JSF?

Answer 1

Well thank you a lot, I did more googling before finding your second reply and found some info about filters, I will check your links as well and
see if I can polish my solution based on your links.
For those who might look for solving the same issue:
I added to web.xml this (my faces are prefixed with "/fx" rather than "/faces", a matter of taste):
<filter>
          <filter-name>JsfFilter</filter-name>
          <filter-class>xlinuks.JsfFilter</filter-class>
          <init-param>
               <param-name>search_token</param-name>
               <param-value>.jsp</param-value>
          </init-param>
          <init-param>
               <param-name>add_token</param-name>
               <param-value>/fx</param-value>
          </init-param>
     </filter>
     <filter-mapping>
          <filter-name>JsfFilter</filter-name>
          <url-pattern>*.jsp</url-pattern>
     </filter-mapping>And the filter itself is this:
package xlinuks;
import java.io.IOException;
import javax.servlet.*;
import javax.servlet.http.*;
public class JsfFilter implements Filter {
     private FilterConfig filterConfig;
     private String sSearchToken, sAddToken;
     public void doFilter( ServletRequest request, ServletResponse response, FilterChain chain ) throws ServletException, IOException {
          HttpServletRequest httpReq = (HttpServletRequest) request;
          String sUri = httpReq.getRequestURI();
          if( (sAddToken == null) || (sSearchToken == null) ) {
               chain.doFilter( request, response );
               return;
          int iIndex = sUri.indexOf( sSearchToken );
          if( (iIndex > -1) && (sUri.indexOf( sAddToken ) < 0) ) {
               sUri = sAddToken + sUri.substring( sUri.lastIndexOf( "/" ) );
               filterConfig.getServletContext().getRequestDispatcher(sUri).forward(request, response);
               return;
          } else {
               chain.doFilter(request, response);
     public void init(FilterConfig filterConfig) throws ServletException {
          this.filterConfig = filterConfig;
          sSearchToken = filterConfig.getInitParameter( "search_token" );
          sAddToken = filterConfig.getInitParameter( "add_token" );
     public void destroy() {
          filterConfig = null;
}
