Class ActionContextCleanUp

java.lang.Object
  org.apache.struts2.dispatcher.ActionContextCleanUp

All Implemented Interfaces:

javax.servlet.Filter

Deprecated. Since Struts 2.1.3, use StrutsPrepareFilter and StrutsExecuteFilter to use other Servlet filters that need access to the ActionContext

public class ActionContextCleanUp
extends Object
implements javax.servlet.Filter

Special filter designed to work with the FilterDispatcher and allow for easier integration with SiteMesh. Normally, ordering your filters to have SiteMesh go first, and then FilterDispatcher go second is perfectly fine. However, sometimes you may wish to access Struts features, including the value stack, from within your SiteMesh decorators. Because FilterDispatcher cleans up the ActionContext, your decorator won't have access to the data you want.

By adding this filter, the FilterDispatcher will know to not clean up and instead defer cleanup to this filter. The ordering of the filters should then be:

• this filter
• SiteMesh filter
• FilterDispatcher
