  Direct Known Subclasses:
    CombinedRealm, DataSourceRealm, JAASRealm, JDBCRealm, JNDIRealm, MemoryRealm, NullRealm, UserDatabaseRealm

      public abstract class RealmBase
      extends LifecycleMBeanBase
      implements GSSRealm

  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.
