Hi,
Hmm... I'd guess it should go in the same repository as the normal
WebappLoader, which is $CATALINA_HOME/server/lib.
$CATALINA_HOME/server/classes should be functionally equivalent for
unpacked classes, so it's strange you get the CNFE when you put your
loader there. Try packaging your loader in a jar file and putting that
jar in server/lib.

Subject: ClassNotFoundException implementing new WebappLoader
Hello,
I'm trying to implement and register a new WebappLoader implementation
with
Tomcat 5.0.19. I've created a subclass of the standard WebappLoader
class.
In addition, I have added the Loader element to my Context element with
my
new class name specified. When starting the server, I get a
ClassNotFound
exception when it attempts to do a Class.forName for my class in the
CreateLoaderRule.begin method. I've tried my class in tomcat-
root/common/classes and also in tomcat-root/server/classes with no
luck.
Can anyone offer any idea what I might be doing wrong and how I might
solve
the problem?
Thanks,
Craig
