The following article describes the Difference Between a JSP and a Servlet.
JSP and Servlet are both Java technologies that we use for web application development. Although they share some similarities, there are some key differences between the two.
Key Difference Between a JSP and a Servlet
In fact, JSPs are an extension of Servlets: JSPs are built on top of Servlets. Basically, they provide a higher-level abstraction for web page development. Furthermore, JSPs allow developers to embed Java code within an HTML page. Whereas Servlets require developers to write Java code to generate the HTML output.
- HTML vs. Java Code. Actually, we use JSPs to primarily generate HTML output. Whereas, we use Servlets to handle requests and generate dynamic content on the basis of user input or other factors. JSPs are designed to make it easier to create HTML pages with dynamic content, while Servlets are more focused on handling HTTP requests and responses.
- Page Compilation: JSPs are compiled into Java servlets by the JSP container, which means that they are compiled only once when they are first accessed. This allows for faster performance when the page is accessed multiple times. Servlets are also compiled into Java classes, but they are compiled every time they are changed, which can slow down the development process.
- Page Management: JSPs can be managed as individual files, which can be useful when working with designers who may not be familiar with Java code. Servlets are typically managed as part of a larger application and are usually packaged into WAR files for deployment.
- Page Structure: JSPs are designed to separate the presentation layer from the business logic layer, which can make it easier to maintain and modify the code over time. Servlets are more focused on handling HTTP requests and responses, and do not have the same separation of concerns as JSPs.
In summary, JSPs are an extension of Servlets and provide a higher-level abstraction for web page development, whereas Servlets are more focused on handling HTTP requests and generating dynamic content. JSPs are designed to make it easier to create HTML pages with dynamic content, while Servlets are more focused on handling HTTP requests and responses.
