The proliferation of mobile computing has led to a radical increase in the requirement for cloud-based systems. Current cloud systems have moved beyond just storage and entire solutions are hosted on the cloud, which enable users to benefit from a variety of SaaS (Software as a Service) and pay as you go plans. Such changes led users to demand a new range of applications capable of seamlessly operating in the cloud and Java’s answer to this demand is its JavaServer Faces 2.0 (JSF 2.0).
JSF 2.0 is designed specifically to facilitate virtualization of available computing resources – a primary requirement for the migration of applications to the cloud. The main factors favoring the use Java have been its security features and the WORA (write once run anywhere) principle. Whereas the second has been duplicated quite successfully by many of the new programming languages, the security aspect has continued to plague newer software. These benefits have also been introduced into the JSF 2.0, which makes it an ideal choice to facilitate Java Application Development for the cloud. Following are key features of Java Server Faces 2.0, which make it ideal for cloud computing:
Specialized Resource Handling
Implicit Navigation Support
JSF 2.0 features implicit navigation features, which are activated if no navigation rules are specified for a specific action or for the output obtained from a specific JSF page. The main purpose of implicit navigation is to ensure efficient allocation of resources within the system/application. The function often redirects to a Facelets page, which bears a name similar to that of the outcome while using an extension, which is same as the current view id of an extension, if, the outcome does not feature a specific outcome. Additionally, the JSF 2.0 also features the @ManagedBean Annotation, which allows users to create managed beans classes, which is automatically added to the ResourceHandler Application.
One of the leading features incorporated into JSF 2.0 is the Ajax support, which may be added to any JSF component. Ajax is capable of providing asynchronous data transfer between a client and a server, which helps in speeding up data transfers in cloud-based systems. The integration helps developers leverage Ajax in Java application development for cloud computing requirements of both individuals and enterprises. Key Ajax features currently supported in JSF 2.0 are component grouping, partial processing of pages and partial rendering of pages.
Pre-emptive navigation Benefits
JSF 2.0 features pre-emptive navigation, which allows users to easily determine the request parameters as well as the resource file the user navigates to, on the basis of view parameters and the navigation case. Pre-emptive navigation thus helps users create a URL for all JSF resources accessed by an user as the final location is not hardcoded. In short, it increases the flexibility provided to developers at the time of Java Apps Development.
Event Handling Features
While using JSF 2.0, developers can access the unique PreRenderView Event Handling system, which allows access to an event subsequent to processing of the view parameters and prior to the view being rendered. This feature allows developers to access an additional step of verification with respect to an application being developed. The feature is especially effective in helping developers speed up the overall development process, by identifying and resolving issues with superior effectiveness.
Cloud computing is big business and 2013 will see a further expansion of this lucrative market. By leveraging the new cloud computing-friendly features of JSF 2.0, many a Java Development Company can be part of this lucrative business. Moreover, Java apps development is also preferred by enterprise users because of the superior security features incorporated into Java-based applications.
