The JDOPermission class is for operations that are reserved for JDO implementations and should not be called by other code. A JDOPermission is a named permission and has no actions. There are two names currently defined. Each named permission has a corresponding public static final field which contains an instance of the named permission.

The following table provides a summary description of what each named permission allows, and discusses the risks of granting code the permission.

Permission Target Name What the Permission Allows Risks of Allowing this Permission
setStateManager This allows setting the StateManager for an instance of PersistenceCapable. The StateManager has unlimited access to get and set persistent and transactional fields of the PersistenceCapable instance. This is dangerous in that information (possibly confidential) normally unavailable would be accessible to malicious code.
getMetadata This allows getting metadata for any PersistenceCapable class that has registered with JDOImplHelper. This is dangerous in that metadata information (possibly confidential) normally unavailable would be accessible to malicious code.
manageMetadata This allows managing metadata for any PersistenceCapable class that has registered with JDOImplHelper. This is dangerous in that metadata information (possibly confidential) normally unavailable would be manageable (modifiable) by malicious code.
closePersistenceManagerFactory This allows closing a PersistenceManagerFactory, thereby releasing resources. This is dangerous in that resources bound to the PersistenceManagerFactory would be releaseable by malicious code.
