This article introduces what is the use of Jsp website space, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Jsp, whose full name is Java Server Pages, is a simplified Servlet plan. JSP uses java to improve its language and security. Today, the vast majority of large corporate websites are built using JSP technology. JSP technology provides a simple and agile way to create Web pages that flash dynamically generated content. The plan of JSP technology is to make it easier and easier to construct Web-based applications that can work with a variety of Web servers, application servers, browsers and development tools.

Because the script language used in JSP pages is Java language, it has all the advantages of Java technology, including perfect storage processing and security. Nowadays, many corporate websites and e-commerce websites choose JSP language to build websites, of course, if we want to be able to work JSP normally, we need to use hosts that can support JSP language, so what is the role of using JSP website space?

First of all, the use of JSP web space can perfectly support the work of JSP programs, and the JSP host has almost unfettered client access and extremely simplified application placement and processing (to update an application, the processor only needs to change a program based on the server, rather than countless applications installed on the client).

Second, static HTML is a good choice for flashing relatively static content; the new challenge is to create interactive applications based on Web, in which the content of the page is based on the user's request or the state of the system, rather than predefined text. An early solution to this problem is to use the CGI-BIN interface; developers write separate programs related to the interface, as well as applications based on Web, which invokes the former through the Web server. Some Web server vendors have now verified that they have simplified the development of Web applications by supplying "plug-ins" and API to their servers. These solutions are related to specific Web servers and do not solve the problem of solutions across multiple vendors.

After all, a Java Servlets is a program that works on the server side based on Java technology (unlike Applet, which works on the browser side), developers can write such a Servlet to accept HTTP requests from Web browsers, dynamically generate references (you may have to query the database to end this request), and then send a reference containing HTML or XML documents to the browser. With this approach, it is necessary for all pages to be made in Java Servlet. Suppose a developer or Web processor wants to adjust the flashup of the page and has to recompile the Java Servlet on the modification side, even if it logically works now. Java Server Pages (JSP) technology is planned to be used to satisfy such requests, and the JSP specification is the result of extensive collaboration among Web servers, application servers, trading systems, and development tool vendors.

What is the use of Jsp website space to share here, I hope the above content can be of some help to you, you can learn more knowledge. If you think the article is good, you can share it for more people to see.
