MyFaces failing to show JSF error page (bug)

Wolf Benz Wed, 23 Aug 2006 02:41:55 -0700

Hi,

Browsing through earlier posts, it appears that if you specify an error-page in the web.xml AND IF this page contains jsf tags (pure jsp & html goes aparently fine), MyFaces throws an Exception.

I've experienced this myself too. Is there a remedy/fix planned?

The code:

In my web.xml I have:

<error-page>

<error-code>404</error-code>

<location>/resources/pages/fileNotFound.jsp</location>

</error-page>

<error-page>

<exception-type>java.lang.Exception</exception-type>

<location>/resources/pages/generalJavaErrorPage.jsp</location>

</error-page>

E.g. the fileNotFound page features:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"

xmlns="http://www.w3.org/1999/xhtml"

xmlns:f="http://java.sun.com/jsf/core"

xmlns:h="http://java.sun.com/jsf/html"

xmlns:t="http://myfaces.apache.org/tomahawk" >

<jsp:directive.page contentType="text/html;charset=utf-8"/>

<html>

<head>

<link href="" rel="stylesheet" type="text/css"/>

</head>

<body topmargin="0" leftmargin="0" rightmargin="0" marginheight="0" marginwidth="0" class="body">

<f:view>

<f:loadBundle basename="x.y.z" var="labels" />

<f:subview id="header">

<jsp:include page="./header.jsp" />

</f:subview>

<h:form id="pageNotFoundForm">

<table align="center" >

<tr>

<td style="vertical-align:middle;" colspan="2">

<h3><h:outputLabel value="#{labels.error_Title}" /></h3>

</td>

</tr>

<tr>

<td align="center" colspan="5" >

<h:outputLabel value="#{labels.error_BadURLTit}" />

</td>

</tr>

<tr>

<td align="center" width="90%" colspan="3" valign="middle" style="error">

<h:outputLabel value="#{labels.error_BadURL1} "/>

<jsp:_expression_>request.getRequestURL()</jsp:_expression_>,

<h:outputLabel value=" #{labels.error_BadURL2}"/>

</td>

</tr>

</table>

</h:form>

<f:subview id="footer">

<jsp:include page="./footer.jsp" />

</f:subview>

</f:view>

</body>

</html>

</jsp:root>

The error I'm getting is:
