Thanks for the info however I have not had any luck. I have put triedTry this:
putting the commons-logging-api.jar in commons/lib, /usr/java/lib, and
/usr/java/lib/ext. I then did the same with the commons-logging-1.0.2
putting both the commons-logging-api.jar and commons-logging.jar in the
same places as well as adding it manually to the classpath. I then
upgraded to jdk 1.4.1 and tried the above again. Wow I don't get it. Is
there a way to see what the classpath that tomcat is seeing or a way to
see what classes are actually loaded into the JVM?
When I run a test program calling the logger simiar(diferent class as
argument) to the one that is causing all of the fuss it runs fine. Any
Ideas?
I created a file called reqinfo.jsp and put it in the $CATALINA_HOME/webapps/ROOT, which should be accessible by the URL:
http://localhost:8080/reqinfo.jsp or whatever port you've configured for the http/1.1 connector.

Another idea -- which I haven't tried yet is to put *ALL* the jars in the $CATALINA_HOME/commons/lib. This was a suggestion from Costin Manolache. Another suggestion from Bill Barker was to try Costin's fix to the Manifrest Class-Path in 4.1.15.
public class MyClassLoader {
private static org.apache.commons.logging.Log log=
org.apache.commons.logging.LogFactory.getLog(
MyClassLoader.class );
private void doStuff(){
System.out.println("log is " + log);
}
public static void main(String[] args) {
new MyClassLoader().doStuff();
}
}
