Product” ] annotation to map the ActionScript version of the Product class Product. To install the BlazeDS turnkey server: In this Getting Started tutorial, you will learn how to: To work with typed objects in this application, first create the ActionScript version of the Product class created in step 1: As a result it does not allow you to work on the Java-based server side of your applications.
BlazeDS tips and tricks. String; public var price: Creating a BlazeDS remoting application. In the blazeds-server project, open messaging-config.
BlazeDS – Wikipedia
Set up the web. AsyncMessage; private function send: Table of contents Setting up your BlazeDS environment Building a messaging application Building a remoting application. A Remoting destination exposes a Java class that your Flex application can invoke remotely.
To make the application more robust and better partitioned, modify the code as follows: A polling channel can be configured with a polling interval, or it can be set up to wait for data at the server-side if dovumentation is not immediately available this approach is generally referred to as long polling.
RemoteObject calls are asynchronous. Ensure Use default location is selected. One of the WAR files, ds-console.
Sometimes, you may want to work with strongly typed objects. Create the value object In the application so far, the list of products returned by the getProducts method is deserialized into dynamic objects. ArrayCollection; [Bindable] dockmentation var products: Java objects returned by server-side methods are deserialized into either dynamic or typed ActionScript objects. Hopefully in future iterations, we’ll see the BlazeDS folks use blazedx Java annotations to configure some of this stuff.
Select Java Project in the project type tree and click Next.
Getting started with BlazeDS
Similarly, in the next step, the instance of the ActionScript Product class passed as an argument documebtation the update method of the RemoteObject is deserialized into an instance of the Java version of the Product class at the server-side.
A second transient connection, drawn from the browser pool, is needed only when data is sent to the server. Create the messaging destination A messaging destination represents a topic of real time conversation that interested parties can subscribe listen to or contribute to by posting their own messages. For instance, if you’re running Tomcat on the default portnavigate a web browser to http: Add a destination called tutorial-chat defined as follows: The BlazeDS blaseds server is a ready-to-use version of Tomcat currently version 6.
When dropped into the Tomcat server that you will eventually deploy to, the BlazeDS console will automagically discover your BlazeDS configuration and provide documentatino monitoring statistics. Building a remoting application. You will need a Java project to work on the server side of the applications built in this tutorial.
Documentatipn this example, messages are published by Flex clients.
Channels themselves are configured in services-config. Add event handlers to improve the application RemoteObject calls are asynchronous. Notice that there is no need to explicitly define a channel for the tutorial-chat destination.
Using the Remoting Service, your application can directly invoke methods of Java objects deployed in your application server, and consume the return value. The method can documentatoin a value of a primitive data type, an object, a collection of objects, an object graph, and more. To subscribe to a destination, you use the subscribe method of the Consumer class. Download the BlazeDS turnkey system I realize that I said that we wouldn’t be using the BlazeDS turnkey system, but we will use bits and pieces of it to build up our own project.
To install the Flex Builder 3 plug-in: To work with typed objects in this application, first create the ActionScript version of the Product class created in step I realize that I said that we wouldn’t be using the BlazeDS turnkey system, but we will use bits and pieces of it to build up our own project.
The ProductDAO class provides the data access logic to retrieve and update products Products are transferred between the client and the server using Product objects value objects. Create the remoting destination A Remoting destination exposes a Java class that your Flex application can invoke remotely. This logical name is mapped to the Java class name as part of the destination configuration in blazeda.
blazeda You should know how all the pieces fit together, and if you need to distribute a template war file to get everything to work correctly, then your solution is probably too complex in the first place. In this tutorial, to avoid dependencies on a specific plug-in, we use a simple Java project. It was invaluable to me as I was building my own BlazeDS system, so I mention here so others might find it useful and use it. In addition, BlazeDS enables the creation of a new breed of real-time data push and collaborative applications.
Install the Flex Builder 3 plug-in. Retrieve the list of products In the newly created tutorial-product project, open the tutorial-product. To make the application more robust and better partitioned, modify the code as follows:. Make sure that you have the JDK 1.
