BlazeDS based message services leverage two types of built-in adapters, namely: Therefore, multiple server-side messaging alternatives easily work with Flex messaging. Subscribe to our newsletter? Shashank Tiwari is the Chief Technologist at Saven Technologies, a Chicago based company that provides cutting edge technology driven business solutions for banking and financial service companies. Besides sharing state information and routing information through the clustered servers, clustering provides for channel failover support.
The other three are as follows: The BlazeDS endpoints are Servlet-based endpoints.
One is needed for the streamed response devepoper the server to the client that the channel hangs on to. 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.
Applications using AMF can eliminate an unnecessary data abstraction layer and communicate more efficiently with servers. Add event handlers to improve the application RemoteObject calls are asynchronous. You can include the same robustness in BlazeDS as well.
To install the BlazeDS turnkey server: Install Eclipse and the Flex Builder 3 plug-in Note: The Producer object allows Flex applications to send messages into the message system. A Remoting destination exposes a Java class that your Flex application can invoke remotely.
HTTP request-response Web services Remote procedure calls involving objects A possible demoting configuration could be as guidde Create the value object In the application so far, the list of products returned by the getProducts method is deserialized into dynamic objects.
Jun 01, 11 min read. The dsadapters project http: Therefore, message producers connected to a clustered server instance can send messages to message consumers connected to a different server within the same cluster.
Many of these external systems and libraries, such as messaging infrastructure, database connections and stateless business services, lend themselves to pooling. Over a million developers have joined DZone.
Getting Started with BlazeDS
Regardless of the server-side technology in place, some sort of network communication is needed when the client-side application running in Flash Player or Adobe AIR needs to communicate with the server. Much like his love for climbing mountains he enjoys programming because it provides endless new discoveries, elegant develoepr, summits and valleys.
This means you must have a way that all requests coming from the Flex client and intended to be handled by the BlazeDS instance are routed by the DispatcherServlet to the MessageBroker.
There is also a Blaxeds API not used in this example which allows messages to be sent into the message system on the server.
BlazeDS – Wikipedia
Matching endpoints and channels are paired, and that’s when a Flex client and BlazeDS server talk to each other. These days he is busy building web 2. Usage of Java NIO provides for scalable connections as blocking connections are replaced by non-blocking asynchronous counterparts. You cannot use the Flex Builder standalone configuration because it is built on top of a minimal version of Eclipse that does not include the Java development environment.
I already worked on the subject cf. In the blazeds-server project, open remoting-config. Although it’s mentioned upfront that BlazeDS helps connect Flash platform applications to Java, it’s important to define it a bit further. 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. Integrating Adobe Flex and Java Learn about Adobe’s tool for coupling together Flash platform-based interfaces with robust Java enterprise servers.
