suggestions (no guarantee):
-- delete all .ser files
-- recompile everything
-- restart ND server
if that doesn't work,
-- run console with 'advanced' option
commandcenterjdk.bat -advanced (windows)
console -advanced (solaris, probably all unix)
-- click 'CP' green light
-- click 'worker properties' tab
-- uncheck 'use ND class loader'
-- try first suggestions again
The ND class loader sometimes chokes on things, particularly if your
project uses custom classes that are found outside the project directory.
People have reported other problems. The main disadvantage of not using
the ND class loader is that 'clear cache' doesn't work. But it makes no
difference to the functionality of your app.
I'm not sure from the log snippet whether or not you have project
preloading on. In either case, check the log messages when the app is
instantiated, either when the server is restarted, in the case of project
preloading, or when the first page is requested, if it is not. If you see
this sort of error, you are wasting your time if you continue trying to
use/test the app. Initialization failures like this tend to stop
intialization, which means that stuff unrelated to the problem at hand will
also fail simply because it needed something to have been initialized that
was not.
