After upgrading from Tomcat 5.0.28 to 5.5.20 none of my applets will load.
In the console I get the following:
load: class multigraph.MultiGraphlet.class not found.
java.lang.ClassNotFoundException  : multigraph.MultiGraphlet.class

This seems to indicate a problem with the classpath, but there have been no
changes to the directory structure or the html generated.
