You can obtain the UserPrincipal and other security details by going through the request or implementing PrincipalAware. Implementing PrincipalAware is preferred.

## Go Through the Request

First obtain the HttpServletRequest and then obtain the security Principal.

## Implement PrincipalAware

Preferred

- Ensure that `servlet-config` Interceptor is included in the Action's stack.
  - The default stack already includes `servlet-config`.
- Edit the Action so that it implements the PrincipalAware interface.
  - The PrincipalAware interface expects a `setPrincipalProxy(PrincipalProxy)` method. You may wish to include a companion `getPrincipalProxy` method.
- At runtime, use the PrincipalProxy reference to invoke methods such as `isUserInRole`, `getUserPrincipal()`, `getRemoteUser()`, `isRequestSecure()`, and so forth.
