What is meant by Java Servlets?
Java Servlets are Java program classes that run on a server to generate dynamic web content and process HTTP requests. They are commonly used in web development to facilitate the processing of web requests and create interactive web applications. Servlets interact with the web server, receive requests from web clients (browsers), and can then respond to these requests accordingly by retrieving data from a database, performing calculations, or executing other actions.
Typical functions of software in the field of "Java Servlets" include:
- Handle HTTP requests: Accepting HTTP requests from web clients (browsers) and processing these requests according to the defined servlet logic.
- Generate dynamic content: Generating dynamic web content, including HTML pages, based on the requests and the provided data.
- Session management: Managing user sessions and state information across multiple requests to enable personalized experiences.
- Database access: Integration with databases to retrieve, update, or delete data used in the web applications.
- Interact with other Java technologies: Integration with other Java technologies such as JavaServer Pages (JSP), Enterprise JavaBeans (EJB), and JavaServer Faces (JSF) for extended functionality.
- Implement security measures: Implementing security measures such as authentication, authorization, and HTTPS encryption to ensure the integrity and confidentiality of transmitted data.
- Logging and error handling: Logging events and error messages to diagnose and troubleshoot issues and facilitate effective error handling.
