In the UNIX operating
environment, if the Java applet does not run after you have verified
that your Java archive is correctly specified, then you should remove
any CLASSPATH environment variables that have been set. The Java archive
files contain all the required classes to run the applets. Your CLASSPATH
might point to old versions of the required classes (for example,
for use with the webAF software). This can cause the applets to fail
to load. Most applications enable you to specify a CLASSPATH at startup,
by using a startup option. This is often safer for running multiple
clients than using the environment variables.
