Difference between JSP and Servlet in J2EE

When discussing J2EE technologies such as JSP (JavaServer Pages) and Servlet, it's important to understand the differences between the two:

1. Definition: JSP is a technology used for creating dynamic web pages that contain both HTML and Java code, while Servlet is a Java program that runs on the server to handle requests and generate dynamic content.
2. Usage: Servlets are used to write Java code directly for handling requests and generating responses. JSP allows developers to embed Java code in HTML pages for dynamic content generation.
3. Structure: Servlets are Java classes that extend the javax.servlet.Servlet interface, while JSP files are compiled into Java servlets before execution.
4. Maintainability: JSP is often preferred for its easier integration with HTML, making it more maintainable for designers and developers working on the same project. Servlets provide more control and flexibility for complex business logic.

Both JSP and Servlet are important components of Java web development in the J2EE ecosystem, and choosing between them depends on the specific requirements of the project.
