What is the difference between JSF Servlet and JSP?

In light of the MVC design pattern, the servlet acts as a controller and JSP as a view, whereas JSF is a complete MVC. As we already know, the servlet will need manual HTML tags in Java code. For the same purpose, JSP uses HTML and JSF uses Facelets. There’s no default support for error handling in servlet and JSP.

How does JSP interact with Java?

JSP pages are relatively quick and easy to build, and they interact seamlessly with Java servlets in a servlet container like Tomcat. You will encounter JSP in older Java web applications, and from time to time you may find it useful for building simple, dynamic Java web pages.

Is JSP part of JSF?

jsf is a framework. jsp is not a request driven model view controller, but jsp is accessed by the dynamically generated web pages like html or xml. jsf supports validator and conversion,ajax.

Why are servlets safe as compared to the other technologies?

Portability: because it uses Java language. Robust: JVM manages Servlets, so we don’t need to worry about the memory leak, garbage collection, etc. Secure: because it uses java language.

What are JSF pages?

JavaServer Faces (JSF) is the Java standard technology for building component-based, event-oriented web interfaces. Like JavaServer Pages (JSP), JSF allows access to server-side data and logic. Examples include new features in JSF 2.3, and we’ll use PrimeFaces for our component library.

Which language is used to write servlets and JSP?

Java language
Servlets are written in the Java language. JSPs on the other hand use a combination of HTML and Java. Eventually JSPs are converted into a pure Java servlet.

What are Java servlets used for?

Although servlets can respond to any type of request, they are commonly used to extend the applications hosted by web servers.

What is JSF Faces Servlet?

What are servlets and JSP?

Sample Java Web Application using Servlets and JSP. A servlet is a java class that is extended to handle the capabilities of a server. Servlets can be used to handle the requests and responses of a server.

What is the difference between Java Server Pages and Java Server Faces?

Java Server Pages is used to create dynamic web pages. Jsp’s were introduced to write java plus html code in a single file which was not easy to do in servlets program. And a jsp file is converted to a java servlet when it is translated. Java Server Faces is a MVC web framework which simplifies the development of UI.

What is server side includes in JSP?

JSP and Servlets and servers for that matter have one very important feature called ‘Server Side Includes’. This means the output of one servlet can be the input of another. It also means that multiple JSP pages and HTML pages can be combined into one HTML page for a single response.

What is a JSP page in Java?

A JSP page is a text file that has a mix of HTML and JSP tags. This page is compiled by the server at runtime into you guessed it, a Servlet and in this servlet the compiler builds all those System.out.println (“…HTML…”); lines for you.
