Action struts 1

Le Action sono gli strumenti grazie ai quali il Controller di Struts gestisce le attività. Ogni Action rappresenta una funzione dell'applicazione, quindi è qui che scriviamo la logica applicativa dei nostri progetti. La classe Action disaccoppia le richieste del client dall'applicazione Introdotti con Struts 1.1, sono definiti dall'interfaccia org.apache.struts.action.Plugin. I Plugin di Struts sono utili quando si allocano risorse o si preparano connessioni a database o su risorse JNDI. Questa interfaccia definisce due metodi che sono init() e destroy(). Per caricare e creare all'avvio tutti i componenti necessari all'applicazione, Struts fa riferimento ad un file di configurazione chiamato struts-config.xml.Questo file ci permette di specificare in maniera dichiarativa il comportamento dei componenti del framework, evitando che le informazioni e il comportamento siano inseriti rigidamente nel codice delle applicazioni I'm working on a little project which uses Struts 1.3 and I encountered the following problem. After some business logic takes place in an Action i want to forward the control to another Action which is mapped in struts-config.xml.. Usually this is the way I'm solving this The Struts 1 plugin allows you to use existing Struts 1 Actions and ActionForms in Struts 2 applications This plugin provides a generic Struts 2 Action class to wrap an existing Struts 1 Action, org.apache.struts2.s1.Struts1Action
