JAASMemoryLoginModule
public class JAASMemoryLoginModule extends MemoryRealm implements LoginModule,Realm(Code)

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 pahtname 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()(Code)




Method Detail
abort
public boolean abort() throws LoginException(Code)
Phase 2 of authenticating a Subject when Phase 1 fails. This method is called if the LoginContext failed somewhere in the overall authentication chain. true if this method succeeded, orfalse if this LoginModule should beignored
exception:
  LoginException - if the abort fails



commit
public boolean commit() throws LoginException(Code)
Phase 2 of authenticating a Subject when Phase 1 was successful. This method is called if the LoginContext succeeded in the overall authentication chain. true if the authentication succeeded, orfalse if this LoginModule should beignored
exception:
  LoginException - if the commit fails



findSecurityConstraints
public SecurityConstraint[] findSecurityConstraints(HttpRequest request, Context context)(Code)
Return the SecurityConstraints configured to guard the request URI for this request, or null if there is no such constraint.
Parameters:
  request - Request we are processing
Parameters:
  context - Context the Request is mapped to



initialize
public void initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options)(Code)
Initialize this LoginModule with the specified configuration information.
Parameters:
  subject - The Subject to be authenticated
Parameters:
  callbackHandler - A CallbackHandler for communicatingwith the end user as necessary
Parameters:
  sharedState - State information shared with otherLoginModule instances
Parameters:
  options - Configuration information for this specificLoginModule instance



load
protected void load()(Code)
Load the contents of our configuration file.



login
public boolean login() throws LoginException(Code)
Phase 1 of authenticating a Subject. true if the authentication succeeded, orfalse if this LoginModule should beignored
exception:
  LoginException - if the authentication fails



logout
public boolean logout() throws LoginException(Code)
Log out this user. true in all cases because thieLoginModule should not be ignored
exception:
  LoginException - if logging out failed
