For a Web application, cookies are used for maintaining specific information about users at client browser side. In the following example, when you click the button, a cookie named "user" will be set and get.
<window use="MyWindow">
<button label="cookie" forward="onCookie()"/>
</window>
And MyWindow.java,
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.zkoss.zk.ui.Executions;
import org.zkoss.zul.Window;
public class MyWindow extends Window {
public void onCookie(){
try {
//add cookie
HttpServletResponse response = (HttpServletResponse)Executions.getCurrent().getNativeResponse();
Cookie userCookie = new Cookie("user", "xxx123");
response.addCookie(userCookie);
//get cookie
Cookie [] cookies = ((HttpServletRequest)Executions.getCurrent().getNativeRequest()).getCookies();
System.out.println(cookies[0].getName());
} catch (Exception e) {
e.printStackTrace();
}
}
}
