    Maven
    is a software tool for project management and build automation.

    While primarily used for Java programming, it can also be used to build and manage projects written in C#, Ruby, Scala, and other languages. Maven serves a similar purpose to the Apache Ant tool, but it is based on different concepts and works in a profoundly different manner.

    Maven is hosted by the Apache Software Foundation, where it was formerly part of the Jakarta Project. Maven uses a construct known as a Project Object Model (POM) to describe the software project being built, its dependencies on other external modules and components, and the build order. It comes with pre-defined targets for performing certain well-defined tasks such as compilation of code and its packaging.

    Maven dynamically downloads Java libraries and Maven plugins from one or more repositories. Maven provides built-in support for retrieving files from the Maven 2 Central Repository and other Maven repositories, and can upload artifacts to specific repositories after a successful build.

    A local cache of downloaded artifacts acts as the primary means of synchronizing the output of projects on a local system. Maven is built using a plugin-based architecture that allows it to make use of any application controllable through standard input.

    Theoretically, this would allow anyone to write plugins to interface with build tools (compilers, unit test tools, etc.) for any other language. In reality, support and use for languages other than Java has been minimal. Currently a plugin for the .Net framework exists and is maintained, and a C/C++ native plugin is maintained for Maven 2 maven-native and maven-nar

    Core Java Tutorial

    This category contains Core Java tutorials. This blog is aimed at experienced programmers who want to learn capabilities of the core Java classes.

    The Core Java technologies and application programming interfaces (APIs) are the foundation of the Java Platform, Standard Edition (Java SE). They are used in all classes of Java programming, from desktop applications to Java EE applications.

    Core java is all the basic classes and API's but we consider Apache Commons as part of core Java due to the large adoption of the Apache commons libraries by the Java community

    Spring Framework 

    The Spring Framework is an open source application framework for the Java platform

    The core features of the Spring Framework can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform. Although the Spring Framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, replacement for, or even addition to the Enterprise JavaBean (EJB) model

    Java Testing using Junit,Cobertura,Maven,...
    Software testing
    is an investigation conducted to provide stakeholders of the application with information about the quality of the product or service tested.

    Software testing also provides an objective, independent view of the software to allow the business to appreciate and understand the risks of software implementation.

    Test techniques include, but are not limited to, the process of executing a program or application with the intent of finding software bugs (errors or other defects).

    Software testing can also be stated as the process of validating and verifying that a software program/application/product:

    • meets the business and technical requirements that guided its design and development; 
    • works as expected; and 
    • can be implemented with the same characteristics. 

    Software testing, depending on the testing method employed, can be implemented at any time in the development process. However, most of the test effort occurs after the requirements have been defined and the coding process has been completed. As such, the methodology of the test is governed by the software development methodology adopted.

    JSF2

    JavaServer Faces (JSF Faces) is a standardized specification for building User Interfaces (UI) for server-side applications. Before JavaServer Faces, developers who built web applications often relied on building HTML user interface components with servlets or JavaServer Pages (JSP pages).

    JavaServer Faces (JSF) is a user interface (UI) framework for Java web applications. It is designed to significantly ease the burden of writing and maintaining applications that run on a Java application server and render their UIs back to a target client.

    JSF provides ease-of-use in the following ways:

    • Makes it easy to construct a UI from a set of reusable UI components 
    • Simplifies migration of application data to and from the UI 
    • Helps manage UI state across server requests 
    • Provides a simple model for wiring client-generated events to server-side application code 
    • Allows custom UI components to be easily built and re-used

    Foundational new features in JSF 2.0

    These features were developed by the expert group specifically to enable other features in JSF 2.0

    • System Events provides a very fined-grained level of detail to observe and act upon the JSF runtime as it processes requests. It is described in detail in Chapter 9.
    • Resources feature allows the JSF runtime to serve up static resources, such as style sheets, scripts, and images, in addition to the previously available capability to serve up JSF pages. 
    • Facelets began as an open-source JSF extension that provided first-class templating and easy integration between markup and the JSF API. This made the experience of writing JSF pages easier and more maintainable. Facelets is now fully included in the core JSF specification in version 2.0 

    New Features in JSF 2

    • Ajax JSF 2 provides now a native support for Ajax. Ajax is an essential element of most production-quality Web applications currently in production. Ajax enables JSF views to communicate with the server directly from the browser without requiring a full-page refresh of the browser window.
    • Composite Components JSF 2 provides a simple way to implement custom components with composites. JSF 2 lets you implement user interfaces that are easy to modify and extend with two powerful features: templating and composite components

    The Java Persistence API, sometimes referred to as JPA, is a Java programming language framework managing relational data in applications using Java Platform, Standard Edition and Java Platform, Enterprise Edition.

    The Java Persistence API originated as part of the work of the JSR 220 Expert Group. JPA 2.0 is the work of the JSR 317 Expert Group.
