I am making a project and deployed in jboss in extended directory form.
All changes are made in netbeans
So i wanted when i make a change in project through netbeans and save than that change directly reflect in jboss server
so i am not wanted to copy and paste file which i make a change
I think that your best bet is to declare JBoss AS as a server in NetBeans (Tools | Servers, then click on Add Server and follow the directions). Then associate your web app project with JBoss AS (project Properties, in the Run category). The NetBeans will automatically deploy the app when you run or debug it in NetBeans.
