Key Differences Between Servlet and JSP in Java Web Development

In Java web development, Servlets and JSP (JavaServer Pages) serve as key components. The fundamental difference between a servlet and a JSP lies in their purpose and functionality.

Servlet:

• Focus Keyword: Servlet
• Servlets are Java classes that extend the capabilities of servers to generate dynamic web content.
• They require a good amount of Java programming knowledge and are ideal for processing request-response logic.
• Servlets offer more control and flexibility in handling complex data processing and business logic.
• They are suitable for applications requiring high performance and low-level interactions with the server.

JSP (JavaServer Pages):

• Focus Keyword: JSP
• JSP is a technology that helps developers combine HTML and Java code for dynamic web content generation.
• Developers can embed Java code within HTML using JSP tags, making it easier to work with web elements and dynamic data.
• JSP allows for the separation of logic and presentation, making it more convenient for web designers to manage the visual aspects of a web application.
• It is suitable for projects where a clear segregation of front-end and back-end tasks is desired.

When to Choose Servlet Over JSP:

If the web application requires extensive server-side processing, complex business logic, and direct control over HTTP requests and responses, servlets are the preferred choice.

When to Choose JSP Over Servlet:

For projects that focus on the presentation layer, require rapid development of web pages, and involve collaboration between developers and designers, JSP is the better option.

By understanding the distinctions between servlets and JSP, you can make informed decisions on when to use each technology in your Java web applications.
