log4j.Logger fails to initialize LogManager

Hello all. I have a Java batch process that is trying to write to the Log4j log file, but it appears that the Logger class is failing to initialize the LogManager class.

Am I understanding this issue correctly? Any idea what would cause this? I have verified that the log4j.jar file is in the .\lib directory.

Any help would be appreciated!

====================

Hi McCormick,

Did you ever manage to solve your problem? I'm getting the same error.

It seems that at runtime some class can't be found (hence the message NoClassDefFoundError) but the name of that class gets lost along the Exception Handling process.

In my classpath, both LogManager and Logger exist.

It's funny that the code seems to fail inside my ThinMPI class, where I do this:


Can anyone help?
