Getting to next JSP from Servlet

Question

I am getting a 404 when I try to redirect from my servlet to an error page. The code that I am testing is....
catch (SQLException es)
LOG.error("Unexpected error in Login.createUser.Error
message = " + es);
session.setAttribute(Constants.MESSAGE, es.getMessage());
session.setAttribute(Constants.ERROR_TITLE, "Login error: " + Constants.SQL_ERROR);
resp.sendRedirect(Constants.ERROR_PATH);
I have a compiled java class called Constants where the ERROR_PATH is defined as
/** Constant name used in obtaining the path to the error page. */
public static final String ERROR_PATH = "/Jsp/error.jsp";
My JSP pages are located at the root...
myapp
....Jsp
....WEB-INF
........classes
My web.xml looks like this
<servlet>
<servlet-name>errorPage</servlet-name>
<jsp-file>/Jsp/errorPage.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>error</servlet-name>
<url-pattern>/Jsp/error.jsp</url-pattern>
</servlet-mapping>
Can anyone point me in the right direction....Thanks

I tend to use a utility method called redirectToResource in particular to redirect from any servlet to any JSP :
/** This method will still work when the server is configured to
*   listen to  port 80 rather than port 8080 (default in Tomcat)
public void redirectToResource (HttpServletRequest req,
                                 HttpServletResponse resp,
                              String resourceName)
                     throws ServletException, IOException
   int serverPort    = req.getServerPort();
   String scheme     = req.getScheme();
   String serverName = req.getServerName();
   StringBuffer urlBuffer = new StringBuffer(40);
   urlBuffer.append(scheme + "://" + serverName);
   urlBuffer.append(":" + serverPort);
   urlBuffer.append(resourceName);
    String location = resp.encodeRedirectURL(urlBuffer.toString());
    resp.sendRedirect(location);
}
