Re: Can't seem to get logging to work in Tomcat 5.5.9

[Rob Tanner <rt...@linfield.edu>]

Georg,

Finally kind of solved my problem.  First, I went to a fresh install of 
5.5.23 and then added the log4j.properties file in 
${CATALINA_HOME}/common/classes and the log4j jar file in 
${CATALINA_HOME}/common/lib. No go.  So, thinking maybe the 
documentation was wrong, I moved the properties file to 
${CATALINA_HOME}/conf.  Again, no go.  The I copied it back to 
common/classes and therefore unintentionally left a copy in conf.  And 
suddenly things started working.  Of course, log level DEBUG is not 
terribly helpful in most cases (too much data) and so I modified the 
properties file, switching it to INFO and things broke.  Then I 
remembered the copy in conf and changed it.  What seems to be happening 
and makes no logical sense is that so long as I have identical copies of 
the log4j.properties file in conf and common/classes, everything works.  
I'm sure that somewhere, something is screwed up, but I have no idea 
what.  Weird!
