JSP full name is Java Server Pages, Chinese named java server pages, the root is a simplification of the Servlet design, it is advocated by Sun Micro systems, led many companies to participate in a dynamic Web page technical standards with the establishment of the. The technology of JSP is similar to ASP technology, it is in the traditional Webpage HTML (asubsetof theStandardGeneralizedMarkup Language) file (*.htm, *.html) to insert the Java program segment (Scriptlet) and JSP marker (tag), thereby forming a JSP file, the suffix (*.jsp).Using Web development of the JSP application is cross platform, which can run under Linux,can also run on other operating system.
It implements html syntax Java expansion (by <% and%, form). JSP and Servlet, are executed on the server. Usually returned to the client side is a HTML text, as long as the client browser can browse.
JSP technology using the Java programming language XML tags and scriptlets, the processing logic to generate dynamic Webpage the package. The application of logic Webpage can exist in the server through the tags and scriptlets to access the resources. JSP will display the separation Webpage logic and Webpage design, support reusable component-based design, make the development of Web based applications more quickly and easily. JSP (JavaServer Pages) is a kind of dynamic page technology, its main purpose is to be separated from said logic in Servlet.
Java Servlet JSP is the technical foundation, and the development of large-scale Web applications need to be completed with Java Servlet and JSP. JSP with the Java technology is simple and easy to use, fully object-oriented, platform independent and reliable safety, mainly for all the characteristics of the internet.
JSP technique can be easily integrated into various application architecture, to use the existing tools and skills, and can be extended to support enterprise class distributed applications. Use of Java technology as part of the family, as well as Java 2 (the structure of enterprise edition system) are an integral part of the JSP technology can support the highly complex Web based applications. Because the JSP page of the built-in scripting language is based on Java, and all JSP pages are compiled into Java Servlets, so JSP pages with all the benefits of Java technology, including robust storage management and security. As part of the Java platform, JSP with the Java programming language, "write once, run anywhere characteristics".
Advantage
(1) write once, run everywhere. In addition to systems, the code not to make any changes.
(2) the multi platform support. Any development environment can be basically on all platforms, to the deployment of the system in any environment, extended in any environment. It is evident in the ASP JSP limitations advantages compared to.
(3) a strong scalability. From only a small Jar documents can run Servlet/JSP, to the multiple servers clustering and load balancing, to multiple Application for transaction processing, information processing, a server to numerous servers, Java shows a great vitality.
(4) the persification and powerful development tools support. This is similar to the ASP, Java has a lot of very good development tools, and many can be free, and many of them have been able to run on a variety of platforms under.
(5) support server-side components. The application of Web server-side components needed to support the strong, developers need to component complex functions using other tools designed for the web page called, in order to enhance the performance of the system. JSP can realize complex business function using the JAVA component of BEANS mature.
