Apache Struts 2 is an enterprise-ready web framework for Java application. It has been designed to streamline the entire development cycle starting from building to deploying. Struts 2 is a combined effort of WebWork and Struts communities. Unlike conventional web applications, it can create dynamic responses. Struts 2 comes with an improved design with clean code for HTTP-independent framework interfaces. Added interactivity and flexibility with AJAX tags gives the look and feel just like standard Struts tags. It doesn’t use Action forms, instead Struts 2 uses JavaBean to capture form input or put properties directly on an Action class. POJO Actions enables class to used as an action class with optional interface. Plugin APIs for the framework include config browser, JasperReports, JavaServer Faces, Pell Multipart, Plexus, sitegraph, sitemesh, tiles and Struts 1. The framework essentially requires Servlet API 2.4,JSP API 2.0 and Java 5.
JavaServer Faces (JSF) is a java web application framework established the standard for development of server-side user interfaces for Java EE application. The JSF APIs are designed to leverage tools that would make we application development increasingly easier. It uses a component based approach. JSF uses JavaServer Pages JSP as its display technology, but it can also support other technologies such as XUL and Facelets . The UI is saved on clients request for new page and restored when the response is returned.
JSF has a set of API for representing user interface components and manages their state, converting values, input validation and event handling, defining page navigation and support for accessibility and internationalization. It has two JavaServer Pages jsp custom tag libraries for expressing a JavaServer Faces interface within a JSP page. Some of its key features include server-side event model, state management, JavaBeans with dependency injection and Unified Expression Language for both JSP 2.0 and JSF 1.2. JSF 2.0 offers improved support for Ajax by allowing UI logic to run partly on the client and not on the server.
- Java EE standard with lots of demand and jobs
- Initially was fast and easy to develop
- Loads of component libraries
- Tag soup for JSPs
- Lacks unified source for implementation
- Doesn’t support REST or Security well
3. Spring MVC
Java/J2EE framework integrating a number of different technologies and is applicable to wide range of projects. Spring is based on code published in Expert One-on-OneJ2EE Design and Development. Spring clearly separates business, navigation and presentation logic. It is a proven web mechanism constructed with a clean web tier. Spring MVC allows users to use any object as a command or form object – there is no need to implement a framework-specific interface or base class. Spring’s features a highly flexible data binding. MVC Model and VIew is based on the map interface that is highly configurable, either via bean names, via a properties file, or via your own ViewResolver implementation. Spring supports controller as an optional command or form object. It has an extremely flexible view resolution that can even write a view directly to the response.
The web framework offers a lot of complex data interactions. It offers powerful type conversion, binding and validation. Stripes has been designed to manage large, complex forms and maps them directly to objects etc. Stripes requires zero external configuration beyond the registration of one servlet and one filter. Stripes provides simple and effective solution to common problems such as indexed properties, multi-event forms, localization and use of domain objects in the web tier. It is a compact web development framework with just few dependencies.
It is an object oriented powerful, open-source, all-Java framework for creating leading edge web applications in Java. The framework allows implementation of applications according to the model-view-controller design pattern. Tapestry offers an innovative web application development concept in terms of objects, methods and properties instead of URLs and query parameters. It adopts a modular approach to web development by combining user interface components (objects) on the web page and their corresponding Java classes.
It could be a rescue for those looking to avoid scripting environments such as JavaServer Pages or Velocity. It provides a complete framework for creating extremely dynamic applications with minimal amounts of coding. The web development framework focuses on simplicity, ease of use, and relieves programmers from creating enormous block codes.
Apache Wicket is a lightweight component based web application framework for the Java programming language. Wicket is patterned after stateful GUI frameworks. It features trees of components that use listener delegates to react to HTTP requests against links and forms. With XHTML for templates it separate presentation and business logic and allows templates to be edited with conventional WYSIWYG design tools. Within the framework each component is backed by its own model that represents the state of the components. Wicket might be the best framework for making use of your developers resources.
7 . RIFE
This is a unique framework for web development and design with tools and APIs to implement commonly used web features. It has been designed for separating tasks during a development cycle, ensuring that each developer or designer focuses on his own tasks. If needed the any work can be effortlessly integrated with the work of the rest of the team. RIFE’s has a number of independently usable toolkits, which can be integrated to boost productivity. All the declaration and definitions in RIFE is handled in one place in the code. This makes it easy for the developers to reduce code replication, enforce consistency, and ease the maintenance. This results in a loosely coupled and very robust system.
It combines the best of request based and component approach to offer consistent component based object model. RIFE’s design provides the best of request-based and component-based approaches and blends them together in a consistent component object model. The web engine provides a solution that values maintainability without compromising on productivity. Through a centralized site structure, an application can be split up into easily reusable binary modules that can be seamlessly integrated into other projects. There is a wide scope for incremental improvements with little or no risk of unwanted anomalies in the system.
open source web application framework developed by JBoss. Seam offers a perfect platform for building rich Internet applications in Java. It is a unified full-stack solution that integrates technologies such as Ajax, JavaServer Faces (JSF), Java Persistence (JPA), Enterprise Java Beans and Business Process Management (BPM) into tooling. Seam also expands the concept of contexts. All the Seam component are enclosed within a context. The default Seam context is conversation which can span multiple pages and usually spans the whole business flow, from start to finish. All the actions in a session context is captured until the user logs out or closes the browser. WYSIWYG development in Seam is facilitated through the use of JBoss Tools.
9. Google Web Toolkit (GWT)
10 . OpenXava
It is a web development framework for creating Ajax Enterprise applications with Java. OpenXava has been designed by Java developers looking for a productive Java Enterprise applications. In OpenXava developers have to provide only the JPA classes to obtain a full featured application ready for production. It requires no code generation. It allows rapid and easy generation of CRUD modules and report generation. It also allows the flexibility to develop complex real life business applications as customer relationship, invoicing, accounting packages, warehouse management, etc. It The web framework offers full Ajax support and can be used on application server (Tomcat, JBoss, WebSphere, etc).
