Okay: that means that the JAR file itself is being loaded properly
(unless you happen to have class files laying around in the webapp's
deployment directory, outside of WEB-INF: make sure you aren't doing
that; I'm pretty sure that archive="...." indicates that all code should
come from the specified JAR and classes will not be requested from the
server directly).

What do you get when you run:

$ unzip -v webapps/schedule.jar

Unless you have written this incorrectly, scheduler.jar shouldn't be in
"webapps/scheduler.jar"... it should be in
webapps/[yourappname]/scheduler.jar. And your applet tag should look
like this:

<applet archive="<%= request.getContextPath() %>/scheduler.jar"
   ...
