Retrieving Credentials From an Enterprise Bean Using the JAAS API

OC4J supports the use of standard JAAS API to retrieve the Subject, Principal, and credentials from within business methods and life cycle methods of session beans (stateless and stateful) and entity beans.

Example 22-10 shows how you can use the JAAS API to retrieve credentials in a business method of an enterprise bean deployed to OC4J.

Example 22-10 Using JAAS API to Retrieve Credentials

public class Calculator {
    // Buisness method
    public void setNewRate(int rate) {
    ...
        AccessControlContext actx = AccessController.getContext();
        Subject subject = Subject.getSubject(actx);
        Set principals = subject.getPrincipals();
    ...
    }
}
