Adding Java program Fragments (scriptlet) and JSP tags (tag) to the traditional Web page HTML file (*.htm,*.html) forms the JSP Web page (*.jsp). When a Web server encounters a request to access a JSP Web page, it first executes the program fragment in it, and then returns the execution results to the customer in HTML format. Program fragments can manipulate databases, redirect Web pages, and send emails, and so on, which is the functionality required to build dynamic Web sites. All programs operate on the server side, the network sent to the client is only the result of the minimum requirements for customer browsers, can be achieved without plugin, no ActiveX, no Java applets, even without frame.
JSP (Java Server pages) is a Dynamic Web page technology standard that is initiated by Sun Microsystems Corporation and many companies are involved in. JSP technology is similar to the ASP technology, it is in the traditional Web page HTML file (*.htm,*.html) Insert Java program Segment (scriptlet) and JSP tags (tag), thus forming a JSP file (*.jsp). Web applications developed with JSP are Cross-platform, run on Linux, and run on other operating systems.
The advantages of JSP:
• Updates to the user interface are actually done by the WEB server, so the feeling is updated quickly.
• All applications are server-based, so they can be kept up to date at all times.
• Client interfaces are not cumbersome and are easy to deploy, maintain, and modify for a variety of applications.
