Difference between Servlet and JSP
Brief Introduction: Servlet technology is used to create a web application. A servlet is a Java class that is used to extend the capabilities of servers that host applications accessed by means of a request-response model. Servlets are mainly used to extend the applications hosted by web servers, however, they can respond to other types of requests too. For such applications, HTTP-specific servlet classes are defined by Java Servlet technology.
JSP is used to create web applications just like Servlet technology. A JSP is a text document that contains two types of text: static data and dynamic data. The static data can be expressed in any text-based format (like HTML, XML, SVG, and WML), and the dynamic content can be expressed by JSP elements. Difference between Servlet and JSP
The difference between Servlet and JSP is as follows:
Servlet JSP Servlet is a java code. JSP is a HTML based code. Writing code for servlet is harder than JSP as it is HTML in java. JSP is easy to code as it is java in HTML. Servlet plays a controller role in the hasMVC approach. JSP is the view in the MVC approach for showing output. Servlet is faster than JSP. JSP is slower than Servlet because the first step in JSP lifecycle is the translation of JSP to java code and then compile. Servlet can accept all protocol requests. JSP only accepts HTTP requests. In Servlet, we can override the service() method. In JSP, we cannot override its service() method. In Servlet by default session management is not enabled, user have to enable it explicitly. In JSP session management is automatically enabled. In Servlet we have to implement everything like business logic and presentation logic in just one servlet file. In JSP business logic is separated from presentation logic by using javaBeans. Modification in Servlet is a time consuming task because it includes reloading, recompiling, JavaBeans the and restarting the server. JSP modification is fast, just need to click the refresh button.
