XMLLayout

[Philippe Waltregny <ph...@nrb.be>]

Hello,

Sorry to bother you but is anybody able to help me?



I'm trying to use log4j's XMLLayout.



Here are my source codes:

1) log4j-events file

<log4j:event logger="java.logging.log4j.Test" timestamp="1089795669140"
level="DEBUG" thread="main">
<log4j:message><![CDATA[Hello World!]]></log4j:message>
<log4j:locationInfo class="java.logging.log4j.Test" method="execute"
file="Test.java" line="36"/>
</log4j:event>

<log4j:event logger="java.logging.log4j.Test" timestamp="1089795697406"
level="DEBUG" thread="main">
<log4j:message><![CDATA[Hello World!]]></log4j:message>
<log4j:locationInfo class="java.logging.log4j.Test" method="execute"
file="Test.java" line="36"/>
</log4j:event>


2) log4j.xml file

<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE log4j:eventSet SYSTEM "log4j.dtd"
[
<!ENTITY logEntity SYSTEM "log4j-events">
]>
<log4j:eventSet
        version="1.2"
        xmlns:log4j="http://jakarta.apache.org/log4j/";>
        &logEntity;
</log4j:eventSet>



Here is the result when I open the log4j.xml file in Microsoft Internet Explorer
6.0:



The XML page cannot be displayed 
Cannot view XML input using XSL style sheet. Please correct the error and then
click the Refresh button, or try again later.

Reference to undeclared namespace prefix: 'log4j'. Error processing resource

<log4j:event logger="java.logging.log4j.Test" timestamp="1089795669140"
level="DEBUG" thread="main">



Would you please tell me what's wrong?

Thank you.
 
Philippe

You can't see the output in I.E. as the output from the Log4j XMLLayout is not 
valid xml - Log4j omits the XML declaration and the default root node 
(including namespace declaration) if you check the source this is to allow the 
layout to be used with other appenders etc, but either way you will need to 
include the output into a valid XML document.
