Here is the code for DefaultAdhocObjectFactory that is the cluprit:
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
if (classLoader == null) {
classLoader = DefaultAdhocObjectFactory.class.getClassLoader();
}
try {
// fails here
return Class.forName(className, true, classLoader);
}
Looks like the PasswordReset.class is coming from some unexpected ClassLoader.
I don't have firsthand experience with Atmosphere deployments (on Tomcat or
otherwise), so not sure what happens there ClassLoader-wise. So a random
question - do you keep Cayenne jar in the same war as your PasswordReset.class?
Or if you are not using a .war, how is your deployed app structured?
