Java is widely utilized in web development, particularly for server-side operations. Java web applications are internet-based distributed applications that enable interaction through dynamic web pages. The Java EE (Enterprise Edition) platform offers diverse Java technologies for web development, providing services such as distributed computing and web services. Java allows developers to create applications without the need for additional scripting languages. Let’s explore the process of creating web applications using Java.

Java Web Application
A web application facilitates communication between clients and servers, enabling access to information. Java is well-suited for developing extensive web applications due to its capacity to interact with numerous systems. Java web development also allows access to services such as peer-to-peer web services, database connectivity, and backend services.
Java Web Application Technologies
Servlet API
The javax.servlet package includes various interfaces such as servlet, filter, filter chain, and servletconfig. Servlet enhances the functionality of servers hosting applications. Web applications created with servlet in Java adhere to the request-response model. A servlet has a lifecycle that begins with initialization and ends with collection by the garbage collector. Servlets offer a platform-independent solution for web development, aiding in various tasks such as gathering input through web forms and displaying data from databases or other external sources. These Java programs operate within web applications, facilitating the transfer of client requests to databases or servers. Servlets assist in managing client requests, processing them, and delivering results after interacting with the database.

JSP
Developers use JavaServer Pages (JSP) technology to swiftly create web content that is independent of platforms and servers. Instead of relying on separate CGI files, JSP technology allows for the integration of dynamic elements within HTML pages, with access to the complete range of Java APIs.
JSP tags facilitate web development by enabling the incorporation of Java code into HTML pages. A JSP page contains both static data, which can be in formats like HTML, WML, XML, and elements of JSP technology governing the dynamic behavior of web content. JSP technology permits the direct inclusion of snippets of servlet code within a text-based document. JSP, a key technology in Java EE, assists developers in quickly constructing intricate dynamic web pages. Looking for standard, affordable Python Training in Chennai?

JDBC API
Java Database Connectivity (JDBC) provides methods and queries for accessing databases. Through web applications containing JDBC drivers, clients can update database information. The four types of JDBC drivers used to connect to databases are the JDBC-ODBC Bridge Driver, Native Driver, Network Protocol Driver, and Thin Driver.
Using the JDBC API, clients can connect to the database, manipulate data, and perform operations such as updating, deleting, and saving information. JDBC is capable of reading any database and can automatically generate an XML format of the data from the database.
The JDBC API facilitates both synchronous and asynchronous processing, presenting processed results to clients in a straightforward manner. It supports various SQL statements and queries for database connection.

Java Persistence API
Java Persistence API (JPA) utilizes object-relational mapping to establish a connection between an object-oriented model and a database. It simplifies the management of relational data in Java applications, aiding in the persistent storage and retrieval of large datasets from the database. With JPA, you can communicate with the database using an object-relational approach without the need for excessive code or proprietary frameworks. JPA comprises a set of effective classes and methods that facilitate the connection to the database.
JavaServer Faces Technology
JavaServer Faces (JSF) Technology is a user interface (UI) framework that enables the creation of web-based interfaces. JSF offers a straightforward model for generating components in different scripting or markup languages. The UI widgets are linked with data sources and server-side event handlers. Through JSF, standard UI components can be reused and extended when building interfaces, ultimately reducing the effort required for creating and maintaining web applications.
