Class HiveLockFilter

java.lang.Object
  net.sourceforge.hivelock.HiveLockFilter

All Implemented Interfaces:

java.util.EventListener, javax.servlet.Filter, UserEventListener

public class HiveLockFilter
extends java.lang.Object
implements javax.servlet.Filter, UserEventListener

Servlet Filter that will notify the SecurityFilter of the Principal of the user executing the current request (thread).

This Filter should be located after the current user has been assigned a Principal, and also after HiveMindFilter.

If you use Max Cooper's SecurityFilter, and assuming that your SecurityRealm uses HiveMind to access a service to check the credentials of the current user, then you would have the following chain of Filters configured:

1. org.apache.hivemind.servlet.HiveMindFilter
2. net.sourceforge.hivetranse.web.HiveMindRegistryPublishFilter
3. org.securityfilter.filter.SecurityFilter
4. net.sourceforge.hivelock.HiveLockFilter
