You probably don't want your users to see that message in such that ugly way. To substitute a better error page, use error-page tag
Jsf Exception Handling Best Practices
in the web.xml file, in that you can specify either a Java Exception or an HTTP error code. So in case the type of thrown exception has matched that type mentioned in the web.xml exception-type or the error code that generated by the server has matched error-code that mentioned in the web.xml, the JSF framework will handle it by forwarding the user into the desired view that you've defined for such those errors or exceptions. 1. The Deployment Descriptor web.xml 404 /faces/error.xhtml 500 /faces/error.xhtml java.lang.Exception /faces/error.xhtml State saving method: 'client' or 'server' (=default).

I would like to create a custom error page and have therefore played with the tag in the web.xml configuration file. 404 /error It seems to work http://stackoverflow.com/questions/16039021/error-page-configuration-in-web-xml-transforms-the-http-code-returned-in-case-of in the sense that in case of a 404, the page returned has the correct HTTP body. However the HTTP return code is 200. The expected 404 was correctly received when was not configured. The same soft-404 problem happens if is not specified. /error I am looking for a way to configure this error page without losing the error code. Two more pieces of information that might be useful : The JSF project stage is Production Pretty URLs are being handled by Pretty Faces 3.3.3 with the following @Named(value = "error") @RequestScoped @URLMappings(mappings = { @URLMapping(id = "error", pattern = "/error", viewId = "/faces/error.xhtml")}) public class ErrorController implements Serializable { http jsf tomcat7 servlet-3.0 prettyfaces share|improve this question edited Apr 17 '13 at 19:56 asked Apr 16 '13 at 13:54 clark 173215 Are you sure if you have a way to access http://localhost:8080/YourProject/error from an internet browser? –Luiggi Mendoza Apr 16 '13 at 15:30 Yes.

To do that, just create your custom class, an factory that wrap/override it and add the following into your faces-config.xml: faces-config.xml org.apache.myfaces.context.ExceptionHandlerFactoryImpl This is an example of an ExceptionHandlerFactory, from myfaces code: ExceptionHandlerFactoryImpl.java public class ExceptionHandlerFactoryImpl extends ExceptionHandlerFactory { @Override public ExceptionHandler getExceptionHandler() { return new SwitchAjaxExceptionHandlerWrapperImpl( new MyFacesExceptionHandlerWrapperImpl(new ExceptionHandlerImpl()) , new AjaxExceptionHandlerImpl()); } } If you need a wrapper: ExceptionHandlerFactoryImpl.java public class ExceptionHandlerFactoryImpl extends ExceptionHandlerFactory { @Override public ExceptionHandler getExceptionHandler() { return new CustomExceptionHandlerWrapper(getWrapped().getExceptionHandler()); } } The most important method to override is ExceptionHandler.handle(). MyFacesExceptionHandlerWrapperImpl.java public class MyFacesExceptionHandlerWrapperImpl extends ExceptionHandlerWrapper { //... public void handle() throws FacesException { //... some custom code goes here ... } } Take a look at MyFaces Core source code, to know in detail how ExceptionHandler implementations works. MyFaces ExceptionHandler MyFaces Core provide a custom ExceptionHandler to deal with exceptions and provide detailed information about it. Since 2.0.8/2.1.2 this is disabled on Production environmen
