So I'm using spring security 3.1 on gae. Works fine in dev
environment, on the gae server I get the following class not found
exception.
The class is in my web-inf/classes folder. The class is an interface
for a DAO that is used to look up the user in the gae datastore. The
interface is serializable.
The authentication seems to happen, but once i authenticate all
requests get this exception (as a warning in the gae logs) and no page
or resource returns.
What am I missing? Any leads would be appreciated.
