JavaServer Faces 2.0 for the Cloud

A new article now up on otn/java by Deepak Vohra titled “JSF 2.0 for the Cloud, Part One,” shows how JavaServer Faces 2.0 provides features ideally suited for the virtualized computing resources of the cloud. The article focuses on @ManagedBean annotation, implicit navigation, and resource handling. Vohra illustrates how the container-based model found in Java EE 7, which allows portable applications to target single machines as well as large clusters, is well suited to the cloud architecture.

From the article--

“Cloud services might not have been a factor when JavaServer Faces 2.0 (JSF 2.0) was developed, but JSF 2.0 provides features ideally suited for the cloud, for example:
•    The path-based resource handling in JSF 2.0 makes handling virtualized resources much easier and provides scalability with composite components.
•    REST-style GET requests and bookmarkable URLs in JSF 2.0 support the cloud architecture. Representational State Transfer (REST) software architecture is based on transferring the representation of resources identified by URIs. A RESTful resource or service is made available as a URI path. Resources can be accessed in various formats, such as XML, HTML, plain text, PDF, JPEG, and JSON, among others. REST offers the advantages of being simple, lightweight, and fast.
•    Ajax support in JSF 2.0 is integrable with Software as a Service (SaaS) by providing interactive browser-based Web applications.”
In Part Two of the series, Vohra will examine features such as Ajax support, view parameters, preemptive navigation, event handling, and bookmarkable URLs.
