Subject Re: Component class problem
Date Sun, 15 Sep 2002 19:40:38 GMT

I place my *.class files in /WEB-INF/classes/, changing the name of the 
class (renaming the java file and recompiling ofcourse) makes the page 
work, it is only when I use the name Component with a large C that it 

I can reproduce the "error" on several computers...

Isn't /WEB-INF/classes/ the right place to store the class files ?! If 
not why is it then working when I call the class component, instead of 
Component ?!
