Servlet vs JSP in J2EE - Key Differences

In J2EE, both Servlet and JSP are important components for developing web applications. However, they serve different purposes and have distinct characteristics:

Servlet:

A Servlet is a Java class that extends the capabilities of servers and responds to client requests. It is used to handle the business logic of a web application.

JSP (JavaServer Pages):

JSP is a technology that allows you to create dynamic web pages by embedding Java code within HTML. It simplifies the process of developing web pages by providing reusable components.

Main Differences:

• Servlet is a Java class that processes client requests, while JSP is a markup language that is used to create dynamic web pages.
• Servlets are more suitable for handling complex business logic, whereas JSP is ideal for displaying data and presentation logic.
• Servlets are compiled into Java bytecode, while JSP pages are compiled into servlets before execution.
• Servlets provide better control over the response generation process, while JSP offers easier integration of Java code with HTML.

Both Servlets and JSPs have their own strengths and use cases in J2EE development, and understanding their differences is crucial for building efficient web applications.
