Web applications are distributed applications that run on a number of computers and communicate via the network or server. It comes in handy for the enterprises to update and maintain without the need for software installation on the client computers. Moreover, one application could be used by millions of people. They are used for online retail sales, banking, discussion boards, weblogs, webmail, and, etc.
What are the Java technologies involved in web application development?
Java Servlet API
The Java Servlet runs on the server side without an application of its own as an HTML user interface (UI) or an application GUI. They are used to extend the applications hosted by the web servers. Several web applications are developed with Java Servlet extensions.
JavaServer Pages Technology
It gives a simple and fast way to create dynamic content. It facilitates the addition of snippets of servlet code into the text-based document. JSP contains static data expressed in text-based format namely HTML, Wireless Markup Language (WML) or XML; JSP technology elements which determine the dynamic content construction by the page.
JavaServer Pages Standard Tag Library
It has the iterator and conditional tags to handle flow control, tags for accessing databases with SQL, manipulate XML documents, internalization, and commonly used functions.
JavaServer Faces Technology
It forms the UI framework to build web applications.
Java Message Service API
The combination of Java technology with enterprise messaging, the JMS API forms a powerful tool to solve enterprise computing problems.
JavaMail API and the JavaBeans Activation Framework
It is used to send e-mail notifications. In conjunction, one may use the JavaBeans Activation Framework (JAF) API, which determines the type of data, encapsulate the access, and discover the operations available.
Java API for XML Processing
It is flexible and JAXP facilitates the use of any XML-compliant parser or the XSL processor within the application and supports the W3C schema.
Java Naming and Directory Interface
It provides the functionality of naming and directory, enables the applications to access several naming and directory services.
Frequently Asked Questions
1. What is Java Web Technologies?
Java technologies and frameworks are software libraries that are web-based providing the user interface, or “view-layer”, of Java web applications. Such frameworks are used for defining web pages and managing the HTTP requests generated by those web pages.
2. What are the advanced technologies in Java?
Sun Java Studio Enterprise IDE is a strong set of tools having an integrated framework for the enterprise-grade, fast web application development. It offers advanced debugging and development support for the web services and for the development of the Java EE technology-based web applications.
3. Which edition of Java is used for web applications?
J2SE(Java Platform, Standard Edition)
Also termed as Core Java, this is the Java most basic and standard version. It’s the cleanest version of Java, a basic foundation for all other editions. J2SE is usually taken into consideration to build web applications for the Desktop environment.
4. How Java is used in web applications?
Java Web Application is used to build dynamic websites. Java offers support for the web application through JSPs and Servlets. We can build a website with static HTML web pages but when we want data to be dynamic, we require the web application.
5. Why Java is used for web applications?
Java is the name for both the programming language that can be used for building complex web applications and for the software platform that used this programming language as its most essential component. It is widely used by development companies to build secure, robust and scalable web applications.
6. What are latest Web technologies?
- Blockchain Technology
- AI or Bots
- Mobile-Friendly Website
- Progressive Web App
- Single Page Application
- Motion UI
Depending on the complexity of the web application, the other technologies involved are J2EE Connector Architecture; Java Authentication and Authorization Service (JAAS); Java Architecture for XML Binding (JAXB); SOAP with Attachments API (SAAJ); Java API for XML Registries (JAXR); Java Transaction API (JTA), and, etc.
