![]() ![]() Added the following definition to web.On the Select a Wizard page select the Web > Dynamic Web Project wizard and click the Next > button. Added the icepush.jar to the WEB-INF/lib ICEfaces 3.0.1 and the Eclipse plugins for ICEfaces Tomcat 7.0 Setup Open Eclipse.I think the integration could be the same for GWT or any other app which is deployed in the Servlet-Container. I will show the example of integration of IcePush with existent web-application (Seam/Richfaces). You can find all the necessary information about IcePush integration here. IcePush has a number of ways to integrate, but I’ve chooses the jQuery Integration In my case it was existent Richfaces/Seam-2/JSF application (I was afraid that IcePush may conflict with Richfaces, but it is not the case, IcePush can be integrated completely transparent to the JSF/Seam application, since it integrates on Servlet level). The requirement here is just to have a servlet container. The good thing is that it’s fairly easy to integrate IcePush technology with existent java-web application. It will be immediately pushed to the client and after that client is free to do anything he want to react to the notification. Client call the callback function in which you may do anything (you may call any javascript function as well the a4j:jsFunction if you want to do something through JSF)Īs a result, the client browser will be notified right after the event will occur on the server. Server will notify the client once he will have notifications to send to him. IcePush client (javascript) send the list of subscribed topics he want to listen, server genberate the unique ID for him, after that client establish the connection with the server which listen for response from server. It probably not that visible, but in short – “It works great”. The JSF implementation is a server-wide configuration setting. Before you begin Ensure that your application is configured for JavaServer Faces (JSF) using the specific web.xml context parameters for the implementation that you have chosen. Here is the diagram from the IcePush docs You can use Apache MyFaces 2.0 or the Sun Reference Implementation 1.2 of JSF, or your own implementation. ![]() ![]() There is no need to say that such server-to-client communication open a lot of great features and possibilities to web apps. So it does that right at the moment he have to say something new to the client. This course provides an in-depth coverage of the ICEfaces architecture, its component suite and will give you all the information you need to Web 2. Hi there Today we ‘re gonna see how we could let the user select multiple tree elements, according to JSF 2.0. What I expect from Push is that server itself initiate the push-notification to the client. with regards to previous point we have to increase the period between requests (to make less impact on the server) – but it is not good for user experience, since it will see the updates with a larger delay.So, actually server can be just “overloaded” by that simple requests number of requests to server is linearly depends on the number of browser windows opened, so more simultaneous users we have connected to the server – the higher loading it will have.But in reality it was not “real” push – it just execute periodic lightweight requests (ping server) and asks him – “do you have something new for me ?”. It help to solve several things and optimize code/requests a bit. So sit back, relax, and have your application glide on the wings of this improved version of HTTP.In one of the previous post I show an example of how a4j-push and a4j-poll were used together. It gracefully degrades to the older version of HTTP if any part of your kit doesn't support HTTP/2. All we've had to do so far is upgrade our web.xml, as you've done here on line 2, in support of Servlet 4, and as a result, HTTP/2. Without getting too much into the weeds of how HTTP/2 works, and why you should want it, suffice it to say you should want it. I think it's called Google? I hope I pronounced it properly. It's a faster, simpler, and more powerful upgrade to the HTTP/1.1 we all know and love, based, in part, on work done by some company out in California. In fact, the JSF Servlet is the single most important piece of this whole enchilada, because it's the one way in and out of a JSF app. If you didn't know, all of JSF is based on Servlet technology. Servlet 4.0 is the latest incarnation of the Servlet specification.
