A redirect would change the status code returned to the user agent. It does not go through the filters because it is forwarded, and as such is part of the same request, not a new request.

Here's the deal. I defined in my web.xml the following entry <error-page> <error-code>404</error-code> <location>/portal.do</location> </error-page> When I call, say portal1.do, a page that doesn't exists I get a forward to the portal.do the thing with the forward is seems that it doesn't go thru the application filters again. And why this is not a redirect ? The browser address stays portal1.do instead of portal.do... Here how the stack trace looks when the portal1.do is called ( this is normal, check the second trace) Thread [http-8585-Processor24] (Suspended) CustomServlet.service(ServletRequest, ServletResponse) line: 104 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 252 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 173 FilterSecurityInterceptor.invoke(FilterInvocation) line: 84 SecurityEnforcementFilter.doFilter(ServletRequest, ServletResponse, FilterChain) line: 182 FilterToBeanProxy.doFilter(ServletRequest, ServletResponse, FilterChain) line: 125 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 202 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 173 CustomAuthenticationProcessingFilter(AbstractProcessingFilter).doFilter(Serv letRequest, ServletResponse, FilterChain) line: 305 FilterToBeanProxy.doFilter(ServletRequest, ServletResponse, FilterChain) line: 125 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 202 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 173 HttpSessionContextIntegrationFilter.doFilter(ServletRequest, ServletResponse, FilterChain) line: 225 FilterToBeanProxy.doFilter(ServletRequest, ServletResponse, FilterChain) line: 125 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 202 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 173 ContentReaderFilter.doFilter(ServletRequest, ServletResponse, FilterChain) line: 171 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 202 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 173 RequestUtilsFilter.doFilter(ServletRequest, ServletResponse, FilterChain) line: 114 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 202 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 173 StandardWrapperValve.invoke(Request, Response) line: 213 StandardContextValve.invoke(Request, Response) line: 178 StandardHostValve.invoke(Request, Response) line: 126 ErrorReportValve.invoke(Request, Response) line: 105 StandardEngineValve.invoke(Request, Response) line: 107 CoyoteAdapter.service(Request, Response) line: 148 Http11Processor.process(InputStream, OutputStream) line: 856 Http11Protocol$Http11ConnectionHandler.processConnection(TcpConnection, Object[]) line: 744 PoolTcpEndpoint.processSocket(Socket, TcpConnection, Object[]) line: 527 LeaderFollowerWorkerThread.runIt(Object[]) line: 80 ThreadPool$ControlRunnable.run() line: 684 ThreadWithAttributes(Thread).run() line: 595 Here how the stack trace looks on the forward to /portal.do after 404 was intercepted Thread [http-8585-Processor24] (Suspended (breakpoint at line 74 in CustomServlet)) CustomServlet.service(ServletRequest, ServletResponse) line: 74 ApplicationFilterChain.internalDoFilter(ServletRequest, ServletResponse) line: 252 ApplicationFilterChain.doFilter(ServletRequest, ServletResponse) line: 173 ApplicationDispatcher.invoke(ServletRequest, ServletResponse) line: 672 ApplicationDispatcher.processRequest(ServletRequest, ServletResponse) line: 465 ApplicationDispatcher.doForward(ServletRequest, ServletResponse) line: 398 ApplicationDispatcher.forward(ServletRequest, ServletResponse) line: 301 StandardHostValve.custom(Request, Response, ErrorPage) line: 362 StandardHostValve.status(Request, Response) line: 283 StandardHostValve.invoke(Request, Response) line: 136 ErrorReportValve.invoke(Request, Response) line: 105 StandardEngineValve.invoke(Request, Response) line: 107 CoyoteAdapter.service(Request, Response) line: 148 Http11Processor.process(InputStream, OutputStream) line: 856 Http11Protocol$Http11ConnectionHandler.processConnection(TcpConnection, Object[]) line: 744 PoolTcpEndpoint.processSocket(Socket, TcpConnection, Object[]) line: 527 LeaderFollowerWorkerThread.runIt(Object[]) line: 80 ThreadPool$ControlRunnable.run() line: 684 ThreadWithAttributes(Thread).run() line: 595 Any idea will be greatly appreciated. MC Ps. On weblogic the error handling triggers a redirect and the above problem is not present. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
