com.sun.enterprise.security.SecurityContext

All Implemented Interfaces:

AppServSecurityContext, Serializable

@Service
 @PerLookup
public class SecurityContext
extends AbstractSecurityContext

This class that extends AbstractSecurityContext that gets stored in Thread Local Storage.

This class is used on the server side to represent the security context. Thread Local Storage is a concept introduced in JDK1.2.

SecurityContext

public SecurityContext(String userName,
                       Subject subject)

SecurityContext

public SecurityContext(Subject subject)

Create a SecurityContext with given subject having DistinguishedPrincipalCredential. This is used for JMAC environment.

Parameters:

subject -

SecurityContext

public SecurityContext(String userName,
                       Subject subject,
                       String realm)

SecurityContext

public SecurityContext()

Method Detail

init

public static SecurityContext init()

Initialize the SecurityContext and handle the unauthenticated principal case

getDefaultSecurityContext

public static SecurityContext getDefaultSecurityContext()

getDefaultSubject

public static Subject getDefaultSubject()

getDefaultCallerPrincipal

public static Principal getDefaultCallerPrincipal()

reset

public static void reset(SecurityContext sc)

No need to unmarshall the unauthenticated principal....

getCurrent

public static SecurityContext getCurrent()

This method gets the SecurityContext stored in the Thread Local Store (TLS) of the current thread.

Returns:

The current Security Context stored in TLS. It returns null if SecurityContext could not be found in the current thread.

setCurrent

public static void setCurrent(SecurityContext sc)

This method sets the SecurityContext stored in the TLS.

Parameters:

sc - The Security Context that should be stored in TLS. This public static method needs to be protected such that it can only be called by container code. Otherwise it can be called by application code to set its subject (which the EJB security manager will use to create a domain combiner, and then everything the ejb does will be run as the corresponding subject.

setUnauthenticatedContext

public static void setUnauthenticatedContext()

didServerGenerateCredentials

public boolean didServerGenerateCredentials()

getCallerPrincipal

public Principal getCallerPrincipal()

This method returns the caller principal. This information may be redundant since the same information can be inferred by inspecting the Credentials of the caller.

Specified by:

getCallerPrincipal in interface AppServSecurityContext

Specified by:

getCallerPrincipal in class AbstractSecurityContext

Returns:

The caller Principal.

getSubject

public Subject getSubject()

Description copied from class: AbstractSecurityContext

This method should be implemented by the subclasses to return the Credentials of the caller principal.

Specified by:

getSubject in interface AppServSecurityContext

Specified by:

getSubject in class AbstractSecurityContext

Returns:

A credentials object associated with the current client invocation.

toString

public String toString()

Overrides:

toString in class Object

getPrincipalSet

public Set getPrincipalSet()

postConstruct

public void postConstruct()

newInstance

Returns:

a new instance

Returns:

the current security context

setUnauthenticatedSecurityContext

public void setUnauthenticatedSecurityContext()

Description copied from interface: AppServSecurityContext
