JSF Interview Questions: What You Need to Know

software engineer job descriptionWhen you are working with advanced Java programming, it will be extremely helpful to know the most frequently asked JSF interview questions as well as their answers. JSF stands for Java Server Faces and this particular branch of Java programming has its own dedicated preassembled User Interface (UI) that can make it that much easier for people to program. For those who want to know how to use JSF, there are classes that will help you get your start and get you on your feet when it comes to the 2.0 version of Java Server Face

Before you move onto this version of the JSF programming you need to make sure that you have a solid understanding of how to create Java design patterns and its architecture. at the beginner’s level. There are all kinds of different programming languages that tie back into Java programming. Once you start educating yourself in this language you can even expand your horizons by understanding what it takes to program Java and JSF that work with frameworks for Android. These JSF interview questions, and knowing the answers, will help you get a good start when it comes to programming with this language.

What is required to get started with JSF?

There are a couple of different things that are needed in order to get started with JSF programming. The first thing you will need is a Java SE Developer Kit (JDK). You will also need at least the JSF 1.2 version and an application server. This can be Tomcat or any other standard application server. The final piece of the puzzle is an Integrated Development Environment (IDE) There are many IDEs to choose from such as Netbeans 5.5, Eclipse 3.2.x and others.

What is the JSF architecture?

When it comes to Java programming, it is important to note that different sublanguages such as JDBC and JSF have different architectures. Knowing the architecture for the language you are writing in is a pretty basic set of facts that you need to know. You may need to take a Javascript for beginners course to get yourself up to speed. JSF has been built on the Model View Controller (MVC) framework and this allows for applications to be scaled better and has better maintainability. The JSF works with a framework that works well with Java Web and user interfaces that fit well within the MVC.

How is JSF different from the conventional JSP / Servlet Model?

JSF is basically a much more advanced language than the regular old JSP servlets. Developers need to put together the JSP and servlets by hand whereas JSF is much more high level. You can even think of JSP and servlets as being parts of the engine that help JSF run smoothly rather than features that work side by side.

What are the available implementations of JavaServer Faces?

There are a couple of different implementations when it comes to JSF. There is Reference Implementation (RI) by Sun Microsystems; Apache MyFaces is an open source JavaServer Faces (JSF) implementation or run-time; ADF Faces is Oracle’s implementation for the JSF standard. All three of these will come in handy in the real world once you have fully come to understand what JSF is and what Java truly offers.

What does a typical JSF application consist of?

Applications that are built with JSF programming language usually have three specific features. A typical JSF application consists of the following parts: JSF has JavaBeans components for managing the application state and its behavior. Event-driven development is another part of the typical application. The third and final aspect of these applications are pages that represent MVC-style views; pages reference view roots via the JSF component tree.
