                               javax.servlet.http.HttpServletResponse servletResponse)
                        throws java.lang.Exception

Invokes action registered to provided action path, Provides action chaining, by invoking the next action request. Returns null if action path is consumed and has been invoked by this controller; otherwise the action path string is returned (it might be different than original one, provided in arguments). On first invoke, initializes the action configuration before further proceeding.

Throws:

java.lang.Exception

render

public void render(ActionRequest actionRequest,
                   java.lang.Object resultObject)
            throws java.lang.Exception

Invokes a result after the action invocation.

Results may be objects that specify which action result will be used to render the result.

Result value may consist of two parts: type and value. Result type is optional and, if exists, it is separated by semi-colon from the value. If type is not specified then the default result type if still not defined. Result type defines which ActionResult should be used for rendering the value.

Result value is first checked against aliased values. Then, it is resolved and then passed to the founded ActionResult.

Throws:

java.lang.Exception
