http://issues.apache.org/bugzilla/show_bug.cgi?id=42315 Summary: Error Handling Custom Error Pages Product: Tomcat 5 Version: 5.5.23 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Consider the following content as part of the server.xml ------------------------------------------------- <Host name="www.example.com" appBase="C:/Example/Webapp" unpackWARs="false" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> <Context path="/" docBase="." reloadable="false" privileged="false"> <Manager className="org.apache.catalina.session.StandardManager" pathname="C:/Example/Webapp/WEB-INF/httpsessions.ser"/> </Context> </Host> ------------------------------------------------- In order to make that host available in a local machine, you should add "example.com" to your hosts file (in windows, it's located at C:\WINDOWS\system32\drivers\etc\hosts) Consider the following web.xml for the context defined above: ------------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd";> <web-app> <servlet> <servlet-name>Controller</servlet-name> <servlet-class>com.example.Controller</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Controller</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <error-page> <error-code>500</error-code> <location>/errors/500.htm</location> </error-page> </web-app> ------------------------------------------------- As you can see, a request made to http://www.example.com will be served by the "Controller" servlet, as its "url-pattern" property is set to "/". If I point my browser to http://www.example.com/errors/500.htm Tomcat serves me the right static html file. However, when a ServletException occurs (error 500), instead of showing the static error page defined in the previous web.xml, I get the default Error 500 Tomcat page, and the Catalina.out file shows this: ------------------------------------------------- SEVERE: Exception Processing ErrorPage[errorCode=500, location=/errors/500.htm] ------------------------------------------------- In order to reproduce this bug, consider the following servlet as the Controller.java : ------------------------------------------------- package com.example; import javax.servlet.*; import javax.servlet.http.*; public class Controller extends HttpServlet{ public void init(ServletConfig conf) throws ServletException{ super.init(conf); } public void destroy(){ } public void doGet(HttpServletRequest req,HttpServletResponse res) throws ServletException{ doPost(req,res); } public void doPost(HttpServletRequest req,HttpServletResponse res) throws ServletException{ throw new ServletException("Force Error 500"); } } ------------------------------------------------- I think this is strange bug, as calling the full http://www.example.com/errors/500.htm gives me the page it should be shown when an error 500 occurs, which means Tomcat can access perfectly to that file, but at the time of showing that page as a result of an exception, then it can't access to that location. In order to resolve that issue, I've added the following content to my web.xml file as temporary fix to this issue: ------------------------------------------------- <servlet> <servlet-name>Error500</servlet-name> <servlet-class>com.example.Error500</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Error500</servlet-name> <url-pattern>/errors/*</url-pattern> </servlet-mapping> ------------------------------------------------- This would be the content of the Error500 servlet: ------------------------------------------------- package com.example; import javax.servlet.*; import javax.servlet.http.*; public class Error500 extends HttpServlet{ public void init(ServletConfig conf) throws ServletException{ super.init(conf); } public void destroy(){ } public void doGet(HttpServletRequest req,HttpServletResponse res) throws ServletException{ doPost(req,res); } public void doPost(HttpServletRequest req,HttpServletResponse res) throws ServletException{ try{ res.sendRedirect("/errors/500.htm"); } catch(Exception ignored){} } } ------------------------------------------------- I've tested this on 5.5.23 and 5.5.20.
