How JSP works

All JSP pages are converted to Servelet (. java), and then the JSP Engine calls the Java compiler (. java) compiled into a Class file (. class), which is interpreted and executed by the Java Virtual Machine (JVM. Verify this as follows:

There is a JSP page Test. jsp. Enter http: // localhost: 8080/Test. jsp in the address bar of the browser, and the execution result will appear. At the same time, there are two more files under % CATALINA_HOME % workCatalinalocalhost: _ Test_jsp.java and _ Test_jsp.class, which are Servelet and Class files respectively.
