Examples of com.opensymphony.xwork2.ActionContext

com.opensymphony.xwork2.ActionContext
The ActionContext is the context in which an {@link Action} is executed. Each context is basically acontainer of objects an action needs for execution like the session, parameters, locale, etc.

The ActionContext is thread local which means that values stored in the ActionContext are unique per thread. See the {@link ThreadLocal} class for more information. The benefit ofthis is you don't need to worry about a user specific action context, you just get it:
Finally, because of the thread local usage you don't need to worry about making your actions thread safe. @author Patrick Lightbody @author Bill Lynch (docs)

            using this, other plugins (like OSGi) can plugin their own classloader for a while
            and it will be used by Convention (it cannot be a bean, as Convention is likely to be
