Class DWRAction

java.lang.Object
  org.directwebremoting.webwork.DWRAction

public class DWRAction
extends java.lang.Object

This class represents the entry point to all WebWork action invocations. It identifies the action to be invoked, prepares the action invocation context and finally wraps the result. You can configure an IDWRActionProcessor through a context-wide initialization parameter dwrActionProcessor that whose methods will be invoked around action invocation.
