Re: Servlet refresh

I do not see any other version of my class. I did a through search for the specified class name.   My class file name is login.class. It is in C:\tomcat4.0\jakarta\webapps\examples\WEB-INF\classes   The error from the log file "localhost_examples_log.2001-11-30.txt" is:   2001-11-30 14:05:23 invoker: init 2001-11-30 14:05:23 jsp:
