The Networking Architecture of BlazeDS BlazeDS provides a clean separation of the Selection from Agile Enterprise Application Development with Flex [Book]. In this example I am going to use Spring+BlazeDS integration API for integrating backend Spring based J2EE layer into client layer Flex. So the User Interface is produced using Flex and to take care of the remoting we can use BlazeDS which is Open Source from Adobe. BlazeDS.

January 24, at 7: February 27, at Adding a WebLogic shared library. Pushing data from the server to the client on the server’s initiative and not as a response rnterprise a request.
Using Flex, BEA Workshop, and BlazeDS for Enterprise RIAs
Before moving on to the web application development you’ll want to test the Session Bean. Among others, the BlazeDS proxy capabilities have three important use cases including: The last step is to display the Regions in a grid and the Countries in a second grid.
BlazeDS is deployed as an web appication. Configurable web application that can be clustered and used in cases that desire a higher than normal performance. BlazeDS instances can be clustered wiht the following techniques can be enterpriee to make applications scale better: July 16, at Source files of example projet: May 15, at 7: The dataprovider on the regions DataGrid is bound to the RemoteObject method call’s result.
Configuring JPA project settings. The information is supplied in file named remoting-config. Set of services that can be managed using JMX agents.
The Networking Architecture of BlazeDS – Agile Enterprise Application Development with Flex [Book]
The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java. The in-built data push mechanism has a few limitations as far as high throughput and high volume goes but there are ways to get around this shortcoming. Enterpride web application that leverages the Java Servlets specification. BlazeDS can logically support both messaging domains. A channel can be configured as follows: The client sends a recurring request to the server at a predefined frequency.
Besides, remoting the Spring messaging and security benefits also get extended to Flex applications. On endpoints that support translation and serialization between AS3 and Java or even web servicesa serialization filter is defined to intercept calls to enterprisf endpoint. You can download it from — http: Robust Connection Non-blocking channels allow for greater number of connections to be served provided they are not all active at the same time always.
Spring + BlazeDS Integration API for Flex based Enterprise Apps | ravigeek
String; public var countries: More about the possible configurations can be learned online at http: Therefore, multiple server-side messaging alternatives easily work with Flex messaging. BlazeDS’s demoting capabilities provide fast and efficient data transmission between a Flex client and a Java server with the help of the binary Action Message Format AMF protocol and the built-in blaeds, channels and adapters to support it.
The HR database schema. Suppose you have an web fldx with a service layer implemented by spring beans and want to get a richer user interface?
Next you will add a Dynamic Web project to the Eclipse workspace. Therefore JMSAdapter comes handy when Flex clients are wired up to send and receive messages to and from enterprise systems that use JMS, whereas ActionScriptAdapter is useful for building systems like eenterprise applications to help communicate between two Flex clients.
Notify me of new comments via email. Being open source, BlazeDS is freely available and can be downloaded from http: With the definition of BlazeDS firmly in place, it’s worthwhile to explore Flex client and Java server integration in the larger context of combining the two platforms.
Kindly post a flex applicaiton where below will be explained. Defining the new EJB project.
Flex clients use channels to connect to these endpoints. Now after this initial project setup steps move to J2EE layer development. Parts of the Flex development platform has become Open Source. It simply saves the result to a variable topics. Explaining every bit of the configuration is beyond the scope of this Refcard and is therefore not included.
