In fact, the difference in execution performance is only the first execution. This is because after the first execution of JSP, it will be comp

(2) reusable components The vast majority of JSP pages depend on reusable, cross-platform components JavaBeans or iseisejavabeanstm) to execute more complex processing required by applications. Developers can share and exchange components that perform common operations, or make these components used by more users or customer groups. The Component-Based Approach accelerates the overall development process and balances various o
