Re: java.net.MalformedURLException: no protocol: log4j.dtd

[Jacob Kjome]

I'm not positive this is the reason for your issue, but there have been some recent bugs reported on Log4j and Tomcat about problems using the Xerces-2.2.0 XML parser. You may want to try using the Xerces-2.1 or 2.0.2 parser and see if your problem goes away.

I am using

        Jakarta Log4j version 1.2.7
        Xerces-J version 2.0.2

I have a configuration file called log4j.xml

The first two lines of log4j.xml are:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

When I invoke

 LogFactory.getLog(java.lang.Class)

I observe an exception.

This is the exception stack trace:
