JSP full name is Java Server Pages, Chinese is called java server page, it is a simplified Servlet design, it is advocated by Sun Microsystems company, many companies participate in the establishment of a dynamic web technology standard. JSP technology is a bit similar to ASP technology, it inserts Java program segments (Scriptlet) and JSP tags (tag) into the traditional web page HTML (a subset of the standard general markup language) file (* .htm, * .html) to form a JSP file with the suffix (* .jsp). Web applications developed with JSP are cross-platform and can run not only under Linux but also on other operating systems.

The JSP page is executed by the JSP engine installed on the Web server or on the application server that uses JSP. The JSP engine accepts client requests for JSP pages and generates JSP pages as a response to the client.

JSP pages are usually compiled into Java Servlets, which is a standard Java extension. Page developers can access all Java application environments to take advantage of the expansibility and portability of Java technology. When the JSP page is first called, if it does not already exist, it is compiled into a Java Servlets class and stored in the server's memory. This allows the server to respond very quickly in subsequent calls to the page (which avoids the problem of CGI-BIN generating a new process for each HTTP request).

JSP pages can be included in a variety of different application architectures or models and can be used in federations of different protocols, components, and formats. JSP-based dynamic information publishing technology is an open and extensible standard for building dynamic Web pages. Regardless of the creation tool, developers can use JSP pages to create portable Web applications that run on different Web application servers.

Dynamic page technology in javaweb. Jsp will first be compiled into servlet,servlet and you can directly call the java code to interact with java applications. What jsp writes in is the java code.
