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.

Channels and endpoints connect a Flex client to a BlazeDS server. Matching endpoints and channels are paired, and that’s when a Flex client and BlazeDS server talk to each other.
After this steps this project will look like below in project explorer of Eclipse IDE. Remoting and messaging program that can be extended by using its Java API. It attempts to illustrate some of the most important features of the software and therefore acts as a starting point for developers who are interested in the subject. Learn about Adobe’s tool for coupling together Flash platform-based interfaces with robust Java enterprise servers.
Server startup in ms. One way to do it to use Flex. For high frequency updates this configuration has the overhead of a poll roundtrip for every pushed message and therefore messages can be queued between polls.
Alok balzeds After seeing your log data, it look like your spring annotation tag is not parsed… I suggest you to please check whether you are pointing the correct Spring context xsd file in your WebApplicationContext. Blazedw 19, 6: Its inclusion into future versions of Enerprise is anticipated. Polling is very blqzeds and network intensive.
Non-blocking channels allow for greater number of connections to be served provided they are not all active at the same time always. The three alternative serverside message services in Spring BlazeDS are: The last step is to make the Flex application and see the results.
Caching is a timetested way of increasing performance by avoiding data fetches across the network and using pre-fetched local data instead.
Therefore, message producers connected to a clustered server instance can send messages to message consumers connected to a different server within the same cluster.
The first step is to a make a new WebLogic domain.
Each endpoint defines a type and format of communication. Being open source, BlazeDS is freely available and can be downloaded from http: In this example I am fetching the list of country for Flex client layer.
Hope fllex information is helpful to you. Explaining every bit of the configuration is beyond the scope of this Refcard and is therefore not included. In order to zip the data transferred from the server to the client, a filter can be created to manipulate and compress the outgoing response.
Prior to the existence of this project developers relied on custom factories to integrate Spring and BlazeDS. July 16, at Data Format Optimization AMF3 facilitates a very efficient way of binary transmission of data between the server and the client. Endpoints reside at the BlazeDS end.
Accessing EJBs in Flex with Oracle WebLogic and BlazeDS | Adobe Developer Connection
Fill in your details below or click an icon to log in: The method tag tells Flex that whenever the getAllTopics Method is called the return value will be handled by the getAllTopicsResult method which is defined like this. Along the way, you saw how the Oracle Enterprise Pack for Eclipse and Flash Builder 4 can help you develop more productively.
BlazeDS has acces to all resource pooling strategies that any Java EE web application running in an application server has. ServiceAdapter abstract class sits at the root of the hierarchy. The channel issues polls to the server to fetch data but if no data is available it waits until data arrives for the client or the configured server wait interval elapses.
All built-in bblazeds classes inherit from the ServiceAdapter abstract class. The license is Euro so it is no big deal.
Starting service Catalina Jan 19, 6: PDF for easy Reference. This channel avoids the overhead of polling and keeps the connection open for the entire scope of communication between the client and the server.
