log4j version problem

[Nauman Rafique <nr...@techlogix.com>]

Hi,
I am getting the following  exception
java.lang.ExceptionInInitializerError: java.lang.NullPointerException
        at java.io.FileInputStream.open(Native Method)

        at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:120)

What might be the problem?
The line from which the exception is generated is
Log.fatal(this, ex);

The application is currently using older version of log4j which uses
category not logger. Now I need to replace the old jar with the new jar;
would it create any problems. If it would create problems, where can I find
the help to use older version of log4j?
