the following *kind* of entries in web.xml
  <filter>
    <filter-name>Security Filter</filter-name>
    <filter-class>com.k_int.svc.identity.util.TomcatSecurityFilter</filter-class>
  </filter>
    
  <filter-mapping>
     <filter-name>Security Filter</filter-name>
     <url-pattern>/webservices/search/*</url-pattern>
  </filter-mapping>


Finally, your spring application context will need to make sure it defines the
security service:

  Add the following classes to the hibernate session factory config
        <value>com/k_int/svc/identity/datamodel/PartyHDO.hbm.xml</value>
        <value>com/k_int/svc/identity/datamodel/GrantHDO.hbm.xml</value>
        <value>com/k_int/svc/identity/datamodel/AuthenticationDetailsHDO.hbm.xml</value>
        <value>com/k_int/svc/identity/datamodel/PermissionHDO.hbm.xml</value>
        <value>com/k_int/svc/identity/datamodel/RegisteredOrganisationHDO.hbm.xml</value>


  <bean id="IdentityService" class="com.k_int.svc.identity.service.impl.db.IdentityServiceDBImpl"  init-method="init">
    <property name="sessionFactory"><ref local="YourAppHibernateSessionFactoryForTheSecurityDatabase"/></property>
  </bean>

for later versions of the lib:

create view TC_ROLES as select AUTH.USERNAME as USERNAME, P2.NAME as ROLE from
IDENT_AUTH_DETAILS AUTH, IDENT_PARTY P2, IDENT_USER_ROLE UR where
AUTH.USER_ID=UR.USER_ID and P2.ID=UR.ROLE_ID;


and finally in context.xml

  <Realm className="org.apache.catalina.realm.JDBCRealm"
                 debug="99"
            driverName="org.gjt.mm.mysql.Driver"
         connectionURL="jdbc:mysql://localhost/bank2?autoReconnect=true"
        connectionName="bank2"
    connectionPassword="bank2"
             userTable="IDENT_AUTH_DETAILS"
           userNameCol="USERNAME"
           userCredCol="PASSWORD"
         userRoleTable="TC_ROLES" 
           roleNameCol="ROLE"/>
