Just a shot in dark; have you tried any Java 2(1.2) plug-ins for
the browser? Maybe you are relying on stuff that only Java 2 supports.
Browsers mostly ship with Java 1.1 support if they ship with any at
all....

Are you trying the browser locally, too? If not, are you sure the
filenames have correct case and all exist?

Also, have you tried out the Javasoft forums, or groups.google.com?
Great resources.
