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:


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