A JSP life cycle is defined as the process from its creation till the destruction. This is similar to a servlet life cycle with an additional step which is required to compile a JSP into servlet.
Is JSP still used 2020?
When to use JSP Our Java code is still written on Servlet, not JSP. We have seen a problem in Zhihu: “how to use JSP to connect to JDBC”. Obviously, we can, but not necessarily. JSP looks like HTML, and adds a lot of Java code to it, which is abnormal and not easy to read.

What is difference between JSP and JSF?
JSP is not a request-driven model view controller; however, JSP is accessed by the dynamically created web pages like HTML or XML. In contrast, JSF is a framework having a backing bean model; JSF View moreover faces a servlet controller. JSF supports validator plus conversion, ajax. But, JSP does not.
What is difference between servlets and JSP?
JSP is the view in 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.
