The Difference between a Servlet and a JSP in Java EE

When it comes to Java Enterprise Edition (Java EE) web development, understanding the difference between a servlet and a JSP is crucial.

Servlet

A servlet is a Java class that handles requests and generates responses on the server-side. It is responsible for processing business logic, interacting with databases, and producing dynamic content.

JSP (JavaServer Pages)

A JSP is a technology that simplifies the development of dynamic web pages. It allows embedding Java code within HTML to create dynamic content. JSPs are translated into servlets before being executed by the server.

Key Differences:

• Servlet is a Java class programming model, while JSP is a templating technology.
• Servlets are efficient for complex processing tasks, while JSPs are great for creating the presentation layer.
• Servlets are more suitable for handling business logic, whereas JSPs are more focused on generating the view.

Therefore, understanding when to use a servlet and when to use a JSP is essential in developing robust and efficient Java EE web applications.
