Examples of org.zkoss.zk.ui.WebApp

org.zkoss.zk.ui.WebApp
Represents a Web application. A web application is usually in form of a war file. An application might have multiple Web applications.
In HTTP, Web application represents a servlet context that supports ZK. In other word, a Web application is created if {@link org.zkoss.zk.ui.http.DHtmlLayoutServlet} is declared in web.xml.
To get the current Web application, use {@link Desktop#getWebApp}. @author tomyeh
