RE: Log4j failed to initialize in Jbuilder 2005 web run/debug

[ha...@asconeducation.com]

Hi Jacob, thanks for the reply. 

I tried your suggestion but the problem persisted. Like you (and James,
thanks for your comment btw) I reckoned that there was a problem with
Tomcat as it obviously wasn't starting up, however I had the cause down
to Log4j because that was where it was sticking and other apps start n
debug fine. To rule out the built in TC I tried pointing JBuilder at a
remote tomcat with similar results. I have now moved over to Eclipse and
have run up against exactly the same problem when I attempt to run
Tomcat and debug from within the IDE which suggests it's a whole
combination of things. 

I had hoped to continue messing with this and come up with a solution
which I could pass on to the list (hence taking so long to get back to
yous), but in the meantime I'm building with ant, shipping to a
standalone Tomcat and using the Logging to do my debug. I know a lot of
you prefer this route but for me it's a load of hassle in comparisson
with the 'step through and watch' scenario I'm used to. 

When I get time I'll come back and figure it out

Thanks  again
Hamish

The error looks like it is happening at the Tomcat level.  This probably
means that commons-logging, which Tomcat uses, is finding Log4j in the
classpath and attempting to use it.  Try putting a very simple
"log4j.xml" config file in the Tomcat common/classes directory (or
elsewhere on the classpath) with a console appender and a basic root
logger that logs at the INFO level to the console appender.  That should
remove the unnecessary chatter.

Besides that, it looks like Tomcat isn't even starting up properly.
You're getting
java.lang.ClassNotFoundException:org.apache.catalina.core.StandardServer
.  That can't be good!  Logging for your app isn't even an issue yet
because Tomcat can't even start successfully, therefore you custom
logging initialization isn't even running.  Fix the other issues before
you assume that log4j isn't working.
