What is Java Web technology and how is it used in web applications?
Java technologies and frameworks are cloud-based software libraries providing Java web applications with a user interface, or “view-layer.” These frameworks are used to identify web pages and to handle the HTTP requests created from those web pages. Java Web Server is used for creating interactive websites. Java offers support over JSPs and Servlets for the web application. We can build a website with static HTML web pages but we need the web application when we want data to be dynamic. Java is the name for both the programming language that can be used to build complex web applications and the software platform that made use of this programming language as its most important component. Development companies make extensive use of it to develop stable, robust and scalable web applications.
What are the types of Java technologies involved in web application development?
1. JavaServer Pages Standard Tag Library (JSTL)
The JavaServer Pages Standard Tag Library has the iterator and conditional tags to manage flow control, SQL database access tags, XML document manipulation, internalization, and widely used functions.
2. Java Servlet API
The JavaServlet API runs as an HTML user interface (UI) or GUI application on the server-side, without its own application. They are used to extend applications hosted on Web servers. Many web applications are developed using the Java Servlet extensions.
3. Java Server Pages Technology (JSP)
The Java Server Pages Technology gives an easy and quick way of creating dynamic content. It encourages the incorporation of servlet code snippets into the text-based paper. JSP includes static data presented in text format, namely Wireless Markup Language (WML), XML and HTML. The JSP development elements define the dynamic content construction of the page.
4. Java Message Service API
The Java Message Service API is the combination of Java technology and enterprise messaging. The JMS API is a powerful tool for addressing business computing issues.
5. JavaServer Faces Technology
It forms an important UI framework to build web applications.
6. Java Naming and Directory Interface
It provides naming and directory functionality and allows applications to access multiple naming and directory services.
7. JavaMail API and the JavaBeans Activation Framework
It is used to send updates via e-mail. In conjunction, the JavaBeans Activation Framework (JAF) API can be used to determine the type of data, that encapsulates the access and discovers the available operations.
Apart from Java, other few web technologies are also actively used, they are namely
1. Java Script
2. Single Page Application
3. Blockchain Technology
4. Motion UI
5. Bots or AI
The sophistication of the web applications depends on the employing of various technologies such as the 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.
