              org.apache.struts.actions.LookupDispatchAction

Deprecated. as of Spring 3.0

    @Deprecated
    public abstract class LookupDispatchActionSupport

extends LookupDispatchAction

Convenience class for Spring-aware Struts 1.1+ LookupDispatchActions.

Provides a reference to the current Spring application context, e.g. for bean lookup or resource loading. Auto-detects a ContextLoaderPlugIn context, falling back to the root WebApplicationContext. For typical usage, i.e. accessing middle tier beans, use a root WebApplicationContext.

For classic Struts Actions, DispatchActions or MappingDispatchActions, use the analogous `ActionSupport` or `DispatchActionSupport` / `MappingDispatchActionSupport` class.

As an alternative approach, you can wire your Struts Actions themselves as Spring beans, passing references to them via IoC rather than looking up references in a programmatic fashion. Check out `DelegatingActionProxy` and `DelegatingRequestProcessor`.
