I've been encountering a java.lang.NoClassDefFoundError when launching
Azureus and cannot find any information anywhere about how to correct
it. I would like to get it working again.

Context notes follow: 

- I've been using Azureus for a long time on the same Windows XP PC
without problem.
- I updated to the latest version of Azureus a couple of weeks ago and
continued to use it without problem.
- I've been using the latest JRE also without problem.
- My computer has been working fine in all respects: I've run disk
checks and scans, all of which show it's working fine.
- I had not installed any new software or hardware when the problem arose.
- I'm running the latest Norton antivirus software and there is no
sign of viruses or other problems on my computer.
- I've tried uninstalling Azureus completely, rebooting and
reinstalling, without effect.
- I've also tried uninstalling Java (including separately cleaning the
registry of all related keys), rebooting and reinstalling, also
without effect
- I've tried uninstalling both Azureus and Java and reinstalling from
fresh downloads, still without effect.
- When the launch fails, I do not get any error messages other than
the java error listed below (captured from az_error.log):

java.lang.NoClassDefFoundError

there is a post with your exact error message here:

Unfortunately it is Italian and Google translation is not much help
but I think it may have something to do with a firewall or virus
checker.
Otherwise have you tried reinstalling the previous version of Azureus &/or Java?
