I'm working on setting up Shiro with my Google App Engine project. I have
set up a Realm that doesn't currently do anything yet except:
* Return an empty SimpleAuthorizationInfo object from
AuthorizingRealm.doGetAuthorizationInfo(PrincipalCollection arg0)
* Return an empty subclass of AuthenticationInfo from
AuthorizingRealm.doGetAuthenticationInfo(
AuthenticationToken arg0)
* The AuthenticationInfo subclass returns "new String("credentials")"
from the "getCredentials()" method
* The AuthenticationInfo subclass returns an empty
SimplePrincipalCollection from the "getPrincipals()" method
...However I placed breakpoints in each of these methods to see if they were
even called and they do not seem to be being called at all.
Below is the stack trace that I'm getting:
The server is running at http://localhost:8888/
