Modified: src/share/org/apache/struts/actions LocalStrings.properties
Added: src/share/org/apache/struts/actions ForwardAction.java
IncludeAction.java
Log:
Add standard actions that let you integrate other web application
components via RequestDispatcher.forward() and
RequestDispatcher.include(), but still take advantage of the preprocessing
performed by the controller servlet (such as auto-population and
validation of ActionForm beans).
