Re: Log4J init problem

FYI - replace log4j with updated jar and problem resolved. NOw to tackle the torque problem!

Katherine Stone <[email protected]> wrote:Hello All,

I am really going bonkers over an error with my Log4j init.
I followed instructions here http://mav.sourceforge.net/maverick-manual.html for initializing log4j.
What am I doing wrong?
 
-using tomcat 4.1.24
-log4j-1.1.3.jar in app\WEB-INF\lib
-log4j.properties in app\WEB-INF\lib
 
 
Following are the ERRORS, web.xml, my init servlet, log4j.properties

As a side note I am also having torque init problems using jndi so I don't know if it is some glaring error in web.xml that is causing both of my problems?
 
Thanks in advance,
Kathy
