Did you also copy the database connector jar?

This shouldn't affect the startup. It just means that Tomcat tried to 
save the existing user sessions and restore them at startup, but the old 
sessions are not compatible with the new classes. You could try to 
remove the saved sessions, but that really shouldn't cause the 
application to stop working.
