Problems with log4j and WebLogic
I am trying to get log4j working with a very simple
session bean in weblogic 7.0. The bean works fine if
I comment out all of the logging code. If I leave the
logging code in I get this exception:

Re: Problems with log4j and WebLogic
Posted by Jerry Cattell <je...@yahoo.com>.
Well, I've resolved the immediate problem by adding
the WL_HOME/common/lib/log4j to the PRE_CLASSPATH in
the WebLogic startup script and removing it from the
manifest.
It seems the problem is a more general classpath issue
with WebLogic. I tried using a simple call to
StringUtils in commons-lang and adding it to the
manifest, but I had the same issue finding that class.
If anyone does have any experience with this problem,
I'd love to hear from you, but as it doesn't pertain
to log4j try not to reply to the list.
Thanks,
Jerry

Re: Problems with log4j and WebLogic
Posted by Jerry Cattell <je...@yahoo.com>.
I considered that, but it doesn't seem to be the
problem. Weblogic has a log4j.jar in the common/lib
directory, so I thought it might be using that one
instead. I replaced it with the jar I am using
(renaming it to log4j.jar just in case they are using
the exact name). Then I removed my jar from the EAR
and the classpath from the JAR's manifest file. Still
getting the exact same error. It seems like it really
can't find it anywhere in the classpath, I just don't
know why.
Thanks,
Jerry

Re: Problems with log4j and WebLogic
Posted by Jacob Kjome <ho...@visi.com>.
NoClassDefFoundError means that you probably have conflicting versions of
Log4j in your classpath. Try to set it up where you only have one copy of
log4j.jar in your classpath and see if that fixes things.
