Introduction to Java Servlets

Java Servlets are server-side Java programs that handle client requests and generate dynamic web content. They run on a web server, extending its capabilities by processing incoming requests, managing sessions, and generating responses, typically in HTML. Servlets use the Java Servlet API and are a key component of Java EE for building scalable, robust web applications. They provide a powerful, efficient way to build interactive web pages and can interact with databases, perform business logic, and integrate with other web technologies.

  2. Introduction to Java Servlets Java Servlets are server-side Java programs that handle client requests and generate dynamic web content. They run on a web server, extending its capabilities by processing incoming requests, managing sessions, and generating responses, typically in HTML. Servlets use the Java Servlet API and are a key component of Java EE for building scalable, robust web applications. They provide a powerful, efficient way to build interactive web pages and can interact with databases, perform business logic, and integrate with other web technologies.

  3. What is Java Servlet? A Java Servlet is a Java program that runs on a server and handles requests from web clients, typically browsers. Servlets are used to create dynamic web content by interacting with web clients via the HTTP protocol. Here's an overview of their key features and functions: nareshit.com/courses/advanced-java-online-training

  4. Lifecycle Management Request Handling: Session Management Response Generation Servlets process incoming requests, such as form submissions, by reading data sent by clients. They generate dynamic responses, often in HTML, which are sent back to the client's browser. Servlets are managed by a servlet container (e.g., Apache Tomcat), which handles their lifecycle, including initialization, request handling, and termination They maintain session information across multiple requests from the same client.

  5. Platform Independence: Servlets are written in Java, making them platform-independent. They can run on any server that supports the Java Servlet API. Scalability: Servlets are well-suited for building scalable applications. They can handle large numbers of concurrent requests and can be easily integrated with other Java EE components like EJBs, JMS, and JDBC. Performance: Servlets are designed for performance. They are loaded once and can handle multiple requests, reducing the overhead associated with process creation and resource allocation. Security: Servlets support a range of security features, including authentication, authorization, and data encryption. They can be configured to run in a secure environment and use Java's robust security model. Portability: Since servlets follow the Java EE standard, they can be deployed on any compliant servlet container, such as Apache Tomcat, Jetty, or JBoss. Extensibility: Servlets are highly extensible. Developers can create complex web applications by extending the basic functionality provided by the Java Servlet API.
