1.JSP, relative and absolute paths in the servlet Premise: Suppose your HTTP address is HTTP://192.168.0.1/your Web application for test,path= "/test" then your Web application URL is http://192.168.0.1/test/ If the Jsp,js file is not accessible at all in the Web-inf directory, JSP if placed in the Web-inf directory ca

Some people often ask what is the difference between JSP and Servlet and what is the relationship between them? In fact, Servlet technology was developed for Java server applications very early. We all know that Applet is an application Applet, and Servlet is a server Applet. However, when Microsoft's ASP technology em

Is your Java application running very slowly? Can they afford to keep up with the rising traffic? This article describes the development of high-performance, highly resilient JSP pages and the performance optimization of the servlet technology. The idea is to build as fast as possible and adapt to a growing number of users and their requests. In this article, I'm going to take you through the performance tu

The most annoying part of my learning about JAVA is the configuration of various development tools. Today I will introduce the configuration of servlet IN THE NEXT jsp (first choice for SUN enterprise-level applications. Use the editplus + tomcat tool (a good JSP running platform) To run Servlet,

The absolute path and Relative Path Problems in Servlet and JSP have plagued me for several days. After some efforts, I will share some of my experiences with you. Premise: assume that your Http address is http: // 192.168.0.1/your web application is webapp, then your web application URL is http: // 192.168.0.1/webapp/◆ Directory structure of web applications:◆ Webapp/◆ Web-inf/◆ Classes/◆ Lib/ Web. xml
