Hello,

integration of quartz in vaadin is done the same way as in any servlet.

You would add ContextListener class and define it in web.xml
public class ContextListener implements ServletContextListener {

private ServletContext context = null;

public void contextInitialized(ServletContextEvent event) {
    context = event.getServletContext();
}
public void contextDestroyed(ServletContextEvent event) {
}

}

In web.xml

ContextListener

So you can start and stop the scheduler.

Thanks Andre but when we need to initialize the servlet context in a separate class iam not able to see the quartz scheduler class initialized.

Extend the https://vaadin.com/api/com/vaadin/terminal/gwt/server/ApplicationServlet.html class

Then in your web.xml instead of specifying


<servlet>
    <servlet-name>myservlet</servlet-name>
    <servlet-class>
        com.vaadin.terminal.gwt.server.ApplicationServlet
    </servlet-class>
    <init-param>
      <param-name>application</param-name>
      <param-value>MyApplicationClass</param-value>
    </init-param>
  </servlet>

specify the class of your ApplicationServlet and you should have all in one.

Thanks Andre i did specify ApplicationServlet in the web.xml and class of the application it looks like it was due to the proprties in my quartz configuration file.
