1. Design Ideas Use the jsp http server to explain the local JSP source file and generate the intermediate java source file. Then, the javac compilation tool is called to compile the java source file into a class file. The jsp http server loads and runs the classes defined in the class file. 2. Key Points of Design 1) JSP
