Hi Chris,
Thanks for helping.
I have tried to type "startup.bat" in DOS under $CATALINA_HOME/bin, the
window quickly closed itself again. I also tried to type "catalina run",
and saw the exception, but it does not look helpful too.
C:\Tomcat 4.1\bin>catalina run

I am running it immediatly starting up my PC. How do we know what the
previous error is? I did remember I had such exception before, but I just
can never trigger the same error again.
org.apache.commons.dbcp.SQLNestedException: Cannot create JDBC driver of
class '' for connect URL 'null', cause:
java.lang.NullPointerException
