Push support for Vaadin 6 and 7 using ICEPush


This add-on is unnecessary since Vaadin 7.2. The built in push mechanism is more performant and more reliable and should be used instead of this add-on.

A component that adds push support to Vaadin!

Add the component to your application and call push() in a background server thread to update the application.

Note that you must use org.vaadin.artur.icepush.ICEPushServlet instead of com.vaadin.terminal.gwt.server.ApplicationServlet.

Based on ICEPush 2.0.0 alpha 3. Make sure that you add icepush.jar and icepush-gwt.jar to your WEB-INF/lib.

To use in a portlet you can use the same servlet to provide push capabilities. You need to add a web.xml that contians the following (headers, footers omitted):

    <servlet-name>ICEPush for Portlets</servlet-name>
    <servlet-name>ICEPush for Portlets</servlet-name>

Please note that the add-on uses Servlet API 2.5 so you need a servlet container that supports that version (e.g. Tomcat 6.0 or newer)
