The Java EE 6 Tutorial, Volume I

Accessing an Enterprise Bean Caller’s Security Context

In general, security management should be enforced by the container in a manner that is transparent to the enterprise beans’ business methods. The security API described in this section should be used only in the less frequent situations in which the enterprise bean business methods need to access the security context information, such as when you want to restrict access to a particular time of day.

The javax.ejb.EJBContext interface provides two methods that allow the bean provider to access security information about the enterprise bean’s caller.

You would use programmatic security in this way to dynamically control access to a method, for example, when you want to deny access except during a particular time of day. An example application that uses the getCallerPrincipal and isCallerInRole methods is described in Example: Using the isCallerInRole and getCallerPrincipal Methods.
