MBeanRegistration, LoginModule, Lifecycle, Realm

public class JAASMemoryLoginModule
extends MemoryRealm
implements LoginModule

Implementation of the JAAS LoginModule interface, primarily for use in testing JAASRealm. It utilizes an XML-format data file of username/password/role information identical to that supported by org.apache.catalina.realm.MemoryRealm (except that digested passwords are not supported).

This class recognizes the following string-valued options, which are specified in the configuration file (and passed to our constructor in the options argument:

• debug - Set to "true" to get debugging messages generated to System.out. The default value is false.
• pathname - Relative (to the pathname specified by the "catalina.base" system property) or absolute pathname to the XML file containing our user information, in the format supported by MemoryRealm. The default value matches the MemoryRealm default.

IMPLEMENTATION NOTE - This class implements Realm only to satisfy the calling requirements of the GenericPrincipal constructor. It does not actually perform the functionality required of a Realm implementation.

Constructor Detail

JAASMemoryLoginModule

public JAASMemoryLoginModule()

Method Detail

abort

public boolean abort()
              throws LoginException

Phase 2 of authenticating a Subject when Phase 1 fails. This method is called if the LoginContext failed somewhere in the overall authentication chain.

Specified by:

abort in interface LoginModule

Returns:

true if this method succeeded, or false if this LoginModule should be ignored

Throws:

LoginException - if the abort fails

commit

public boolean commit()
               throws LoginException

Phase 2 of authenticating a Subject when Phase 1 was successful. This method is called if the LoginContext succeeded in the overall authentication chain.

Specified by:

commit in interface LoginModule

Returns:

true if the authentication succeeded, or false if this LoginModule should be ignored

Throws:

LoginException - if the commit fails

initialize

public void initialize(Subject subject,
                       CallbackHandler callbackHandler,
                       Map<String,?> sharedState,
                       Map<String,?> options)

Initialize this LoginModule with the specified configuration information.

Specified by:

initialize in interface LoginModule

Parameters:

subject - The Subject to be authenticated

callbackHandler - A CallbackHandler for communicating with the end user as necessary

sharedState - State information shared with other LoginModule instances

options - Configuration information for this specific LoginModule instance

login

public boolean login()
              throws LoginException

Phase 1 of authenticating a Subject.

Specified by:

login in interface LoginModule

Returns:

true if the authentication succeeded, or false if this LoginModule should be ignored

Throws:

LoginException - if the authentication fails

logout

public boolean logout()
               throws LoginException

Log out this user.

Specified by:

logout in interface LoginModule

Returns:

true in all cases because the LoginModule should not be ignored

Throws:

LoginException - if logging out failed

load

protected void load()

Load the contents of our configuration file.
