Can contain HTML, JavaScript, XML and Java Code whereas Servlets can contain only Java Code, making JSPs more flexible and powerful than Servlets.
However, Servlets have their own place in a J2EE application and cannot be ignored altogether. They have their strengths too which cannot be overseen.
One advantage of JavaServer Pages (JSP) over Servlets is the ease of development and maintenance. JSP allows the embedding of Java code directly into HTML pages using special tags, making it more convenient for web designers and developers to work collaboratively. This separation of concerns between presentation (HTML) and logic (Java code) simplifies the development process, as it enables a cleaner and more maintainable code structure. In contrast, Servlets often require Java code to be mixed with HTML, which can make the code harder to read and maintain, especially for those who specialize in web design rather than Java programming.
