Is it on the Desktop or on the Web?
username.getValue();
//validate the password
password.getValue();
UserFactory.login(user);
Executions.sendRedirect("index.zul");
com.packtpub.zk.media.model.User user = com.packtpub.zk.media.
model.UserFactory.create();
The user instance is stored into the session. For minimal security, which isn't enough
for production environments, we use an implementation of javax.servlet.Filter
and register it in web.xml.
SecurityFilter
com.packtpub.zk.media.controller.SecurityFilter
loginPage
login.zul
SecurityFilter
*.zul
To complete the example, implementation of the filter method doFilter is
as follows:
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException
{
HttpSession session = ((HttpServletRequest) request).getSession();
