How to implement CustomPermissions using JAAS?

I am trying to develop CustomPermission class in JAAS by extending BasicPermission class.
When i try to using this cusotmpermission class in JAAS Policy file and i try to read the permissions as below

...
ProtectionDomain domain =
new ProtectionDomain(cs, null,SimpleAuthz.class.getClassLoader(),principals);
....
....
PermissionCollection pcoll = Policy.getPolicy().getPermissions(domain);
Enumeration pcollEnum = pcoll.elements();

I iterate through the enumeration and print out the permissions. It says unresolved for my CustomPermission class even though i have put this class file in the jar file.

RESOURCE NAME.......5::com.gabhart.security.PageLevelAuthPermission
ACTIONS.............5::
PERMISSION..........5:

unresolved com.gabhart.security.PageLevelAuthPermission
btnUpdate disable)

If i dont provide this class file in jar i was getting NoClassDefFound, now it doesnt so that means it is able to access the class file, but still says its not resovled. I suspect there should be a way of regsitering this class with Java Security or my approach is wrong.
