Hi,
I had sent this to the Tomcat list, but it seems to be more of a jog4j
issue. So trying my luck here :)
Can anyone shed some light as to why I get the following error when I try
to access the JSP..
javax.servlet.ServletException: org/apache/log4j/Category at
org.apache.jasper.runtime.PageCon
Okay, let me finish, I'm sorry I hit send early by mistake. :-)

Much better. Thanks!
The biggest reasons to use log4j, in my mind, are:
1) It is opensource, so if you need to make changes or
You use the product that has superior functionality and
works for you now. Why would anybody choose an inferior
library and then have to waste resources to enhance it
just because it MAY become the standard in the future.
What if Sun doesn't enhance it anymore, or what if they
do and you have
Isn't that what JCP is for?

Oh, and let me add another opinion to my own mail. I think that adding
more and more functionality to the JVM (what Sun is doing now) is not a
good thing. I prefer a lean mean core "engine" and addon JARs. Want SSL?
Add SSL.jar. Want logging? Add logging.jar. Want RDBMS? Add JDBC.jar.
I'd vote

Let me, as a log4j user, give my 2 cents. I looked at the Java 1.4
logging classes and decided they were inferior to log4j. Since log4j is
an external JAR, it will not only be available in JDK1.4 but also in
1.5, ... and you can already use them in 1.3. So log4j is the way to go.

per se.

100% agreed. Log4j is better supported, and probably has an order of

There's a book about Log4j that's excellent.

Hi,
I saw in the 1.4 JDK that there were new classes introduced concerning logging, which
seems to be a base for Log4J. When I take a look at the class hierarchy of Log4J, it is
not a subclass of those JDK logging classes (I think the reason is that Log4J is older
than the 1.4 JDK...).
So, what wi
