Java is the common language used for web development on the server side. These java web applications are distributed applications run on the internet.
Web development with Java allows us to create dynamic web pages where the users can interact with the interface. The users create dynamic web pages in Java in various ways.
The Java web development services like distributed computing, web services, etc., are created by Java EE platform providers.
The application can develop in Java without using any additional scripting language. Let’s see how web applications are made via Java.
Java application
A web application helps clients to interact with the server to access information. Java is perfect for developing large web applications to communicate with many systems. Services like peer-web services, back-end services and database connectivity can also be accessed via java web development. There are many platforms in the java platform. Also, some prominent java web application technologies are used to create the JAVA web application. Java Web Application Development Company provides many offers and services to develop web applications.
Java web applications technology
Many web application technologies provide services like servlet filter and configuration services. Let us see the top best application technology.
1. Servlet API
This servlet package has many interfaces like servlet, filter chain, filter and servlet config, etc. It increases the capability of servers that are used to host applications. The web application development via servlet in Java follows the requesting response model. A servlet has a life cycle from initialized to collected by the garbage collector. Java web application development company provides platform independent service to its users for web development. The servlets are Java programs run on a web application that transfers the request coming from clients to the database/ servers. The servlets help process the client’s request and provide results from the database.
- This Servlet creates a thread for each request not processed with better performance.
- It uses the Java language of portability
- We don’t need to care about the memory leak, garbage collection, etc., by managing Servlets like robust.
- This technology using the java language is secure.
2. JSP technology
JSB, known as Java Server pages technology, is used by developers to create quick web content. The JSP use it to embed the dynamic elements in HTML pages instead of having a different familiar Gateway Interface. It has access to the entire family of Java APIs. Web development can be easy with the help of unique JSP tags. It helps in inserting java code into HTML pages. This page contains static data that can write in HTML, XML, and WML. This JSP technology element governs the dynamic movement of web content. Java web development service can add snippets of servlet code directly in a text-based document via the JSP technology.
How to use JSP
Translation: A java servlet file is created of a “.jsp” file when the code is written. The regular code file is written with HTML and JSP tags, but the file extension recognized is “.jsp”. This is translated into a servlet file.
Compilation: In this, a servlet class available in the step is created into a servlet class file.
Loading: The class creates that loaded into the container, class loader.
Initiation: An instance of this class object id is created. The container manages one or more samples as per the need. AS an object calls seen class in Java, things take place here.
Initialization: JSP method is called by the container, and the initialization takes place.
Processing: All these services and requests are processed.
Destroy: This instance is created to destroy us. All actions needed are processed and done.
3. JDBC API
Java database connectivity contains methods and queries for accessing the database. The client can update information in a database that contains JDBC drivers. There are four types of JDBC available in java technology. They are JDBC-ODBC bridge driver, native driver, network protocol driver, and thin driver. These JDBC are used to connect to the database. Both synchronous and asynchronous processing can do via java database connectivity API. The results will show in a simple way to the clients via JDBC. It supports many SQL statements and queries that can use to connect to the database.
Advantages of JDBC
- It is capable of reading any database depending on the requirements.
- This JDBC automatically creates the XML format of data from the database.
- This does not require the content to convert and provide full support to query and stored procedure.
- This JDBC supports modules.
4. Java Persistence API (JPA)
This Java Persistence API uses object-relational mapping to connect an object-oriented model to the database. Relational data in Java development consulting services can easily manage via java persistence. This JPA helps in storing or retrieving a large amount of data from the database. This Java persistence PAI will provide a simple communication system with the database using an object-relational approach. We don’t have to use the many codes, proprietary frameworks, etc., to interact with the database. This JPA is a collection of efficient classes and methods that can connect us to the database.
5. Java Server faces technology
The complete form of JSF is Java Server faces technology, a UI framework to create web-based interfaces. A Java Server face provides a simple model for yielding components in various scripting and mark-up languages. The UI widget is connected with the data sources and server-side event handlers. The existing UI components with the data sources can be reused and extended in constructing the interface via java server faces. This java server faces technology that helps reduce the efforts in creating and maintaining a web application.
Advantages of JSF
- A rich collection of controls are in JSF and architecture for processing component data, managing the state, and validating user input.
- This JSF support event is based on the notification.
- The JSF supports internationalization and localization with the variable representation of UI through renderers.
