JSP in the path

First, the client path: in the browser parses the path;

　　 1. absolute path: /servletDemo/css/style.css;

　　　　// Ahead there was a slash, and must be added to the project name;

 　　　<%= requset.getContextPath() %>/css/style.css

　　2. The relative path: CSS / the style.css;

　　　　../style.css: in the current path of the upper level looking for style.css

Second, the server route: the server parsed path;

 　　1. absolute path: /css/style.css;

　　　　// absolute path to the server will automatically add the project name, the server absolute path written without any increase in the project name;

　　2. The relative path: CSS / the style.css;

　　　　// server will generally direct path wrong error;

Third, the absolute path comparison:

　　1. Client absolute path: http: // localhost: 8080 /

　　2. The absolute server path: http: // localhost: 8080 / servletDemo /

Note: unified use an absolute path, but be aware that different services and client's writing;
