I have followed the guidelines in the doc.
I read the notes that the procedure in Andreas Sterbenz's Blog : Weblog "seems to document it"
But when I try to run 'java InstallCert myserver.com' I get the error 'Exception in thread "main" java.lang.NoClassDefFoundError: InstallCert'

I tried it on several machines, but I always get the same error.

Does anyone have the solution?
