possible JRE1.5 error?

[nialltimpson]

I've been working on a project involveing many applets, I have been useing
jdk 1.3 on one fast pc and every thing works ok, but I had to transfer to
a slower pc wunning jdk 1.5, and all of a sudden applets take 2 to 3
min's to load when they used to only take 2-3 seconds, these applets are
only at max 15 kb, also now none of the applets are loading and there all
giving the error

This seems to indicate the URL-using classloader cannot find at least
one class or archive. Are you sure the server you use to serve the
applet is correctly configured? How does your applet or object element
look like in the HTML?
