public interface SecurityContext
Unless otherwise indicated, this type must be usable in all Java EE containers, specifically the Servlet and EJB containers.
|Modifier and Type||Method and Description|
Signal to the container (programmatically trigger) that it should start or continue a web/HTTP based authentication dialog with the caller.
Retrieve the platform-specific
Retrieve all Principals of the given type from the authenticated caller's Subject, or an empty set if the current caller is not authenticated, or if the specified type isn't found in the Subject.
Checks whether the caller has access to the provided "web resource" using the given methods, as specified by section 13.8 of the Servlet specification.
Checks whether the authenticated caller is included in the specified logical application "role".
java.security.Principalthat represents the name of authenticated caller, or null if the current caller is not authenticated.
This can be used to retrieve application-specific Principals when the platform's representation of the caller uses a different principal type.
The returned Set is not backed by the Subject's internal Principal Set. A new Set is created and returned for each method invocation. Modifications to the returned Set will not affect the internal Principal Set.
pType- Class object representing the type of Principal to return.
boolean isCallerInRole(String role)
This method can not be used to test for roles that are mapped to specific named Servlets or
named EJB beans. For a Servlet an example of this would be the

Should code in either such Servlet or EJB bean wish to take such mapped (aka referenced, linked) roles into
account, the facilities for that specific container should be used instead. For instance for Servlet that would

Whether the authentication dialog is to be started or continued depends on the (logical) state of the authentication dialog. If
such dialog is currently in progress, a call to this method will continue it. If such dialog is not in progress a new one will be
