Hi there,

I downloaded taglibs (taglibs-20010926 version). 
Then I deployed to tomcat3.3-m4 by copying the war file into webapps.
After hitting test #1, I got an message in stdout,

log4j:ERROR No appenders could be found for category (root).
log4j:ERROR Please initialize the log4j system property.
(The log4j.properties is in classes directory.)

Then I tried to specify the system property log4j.configuration to 
the absolute address of log4j.properties.  The same error is returned.

I looked at log tag class.  I don't see any code that refers to

Is log tag working or working in progress?  
How do I fix the problem I encounted?

Unfortunately log4j's standard log4j.properties mechanism doesn't work in some 
older Servlet environments. In times like this you need to write your own 
Servlet to initialise log4j.

We think this should be a standard feature of log4j. Please mail the log4j list 
for help on this topic.
