 <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">

                     <Valve className="org.apache.catalina.valves.ErrorReportValve"
       errorCode.400="/faces/errors.xhtml"
       showReport="false"
       showServerInfo="false" />

created the servelet class to redirect the error its also not working

package tneb.ccms.consumer;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@WebServlet("/error400")
public class Error400Servlet extends HttpServlet {
    private static final long serialVersionUID = 1L;

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // Set response content type
        
        //System.out.println( request.getRequestURI());
         response.setContentType("text/html");

        System.out.println("error page");
        // Set response status to 400 Bad Request
        response.setStatus(HttpServletResponse.SC_BAD_REQUEST);

       
       
        response.sendRedirect(request.getContextPath()+"/faces/errors.xhtml");
       
    }
    
    
   
}

package tneb.ccms.consumer;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.FilterRegistration;

import java.io.IOException;

public class BadRequestFilter implements Filter {

     private FilterConfig filterConfig;

        @Override
        public void init(FilterConfig filterConfig) throws ServletException {
            this.filterConfig = filterConfig;
        }

        @Override
        public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                throws IOException, ServletException {
            HttpServletRequest httpRequest = (HttpServletRequest) request;
            HttpServletResponse httpResponse = (HttpServletResponse) response;

            try {
                chain.doFilter(request, response);
            } catch (Exception e) {
                if (httpResponse.getStatus() == HttpServletResponse.SC_BAD_REQUEST) {
                    httpRequest.getRequestDispatcher("/faces/errors.xhtml").forward(request, response);
                } else {
                    throw e;
                }
            }
        }

        @Override
        public void destroy() {
            // Cleanup code if needed
        }
    
}
