MemoryRealm
public class MemoryRealm extends RealmBase (Code)
Simple implementation of Realm that reads an XML file to configure the valid users, passwords, and roles. The file format (and default file location) are identical to those currently supported by Tomcat 3.X.

IMPLEMENTATION NOTE: It is assumed that the in-memory collection representing our defined users (and their roles) is initialized at application startup and never modified again. Therefore, no thread synchronization is performed around accesses to the principals collection.

Field Detail
info
final protected String info(Code)
Descriptive information about this Realm implementation.



name
final protected static String name(Code)
Descriptive information about this Realm implementation.





Method Detail
addUser
void addUser(String username, String password, String roles)(Code)
Add a new user to the in-memory database.
Parameters:
  username - User's username
Parameters:
  password - User's password (clear text)
Parameters:
  roles - Comma-delimited set of roles associated with this user



authenticate
public Principal authenticate(String username, String credentials)(Code)
Return the Principal associated with the specified username and credentials, if there is one; otherwise return null.
Parameters:
  username - Username of the Principal to look up
Parameters:
  credentials - Password or other credentials to use inauthenticating this username



getDigester
protected synchronized Digester getDigester()(Code)
Return a configured Digester to use for processing the XML input file, creating a new one if necessary.



getInfo
public String getInfo()(Code)
Return descriptive information about this Realm implementation and the corresponding version number, in the format <description>/<version>.



getName
protected String getName()(Code)
Return a short name for this Realm implementation.



getPassword
protected String getPassword(String username)(Code)
Return the password associated with the given principal's user name.



getPathname
public String getPathname()(Code)
Return the pathname of our XML file containing user definitions.



getPrincipal
protected Principal getPrincipal(String username)(Code)
Return the Principal associated with the given user name.



getPrincipals
protected Map getPrincipals()(Code)
Returns the principals for this realm. The principals, keyed by user name (a String)



setPathname
public void setPathname(String pathname)(Code)
Set the pathname of our XML file containing user definitions. If a relative pathname is specified, it is resolved against "catalina.base".
Parameters:
  pathname - The new pathname



start
public synchronized void start() throws LifecycleException(Code)
Prepare for active use of the public methods of this Component.
exception:
  LifecycleException - if this component detects a fatal errorthat prevents it from being started



stop
public synchronized void stop() throws LifecycleException(Code)
Gracefully shut down active use of the public methods of this Component.
exception:
  LifecycleException - if this component detects a fatal errorthat needs to be reported
