HTML can be opened directly, while jsp can only be opened when it is published to a server such as Tomact. 3. Use "" to write Java code in jsp, but there is no "" in html.

01. What is JSP?

The full name of JSP is Java Server Pages, which is a dynamic web development technology. It uses JSP tags to insert Java code in HTML web pages. Tags usually start with .

JSP obtains user input data through web forms, accesses databases and other data sources, and then dynamically creates web pages.

JSP tags have a variety of functions, such as accessing databases, recording user selection information, accessing JavaBeans components, etc., and can also transfer control information and shared information in different web pages.

02. What is HTML?

HTML (Hyper Text Mark-up Language) is Hypertext Mark-up Language, which is the description language of WWW. The most popular term is a hyperlink. For example, bookmarking a web page means saving its link.

03. The difference between JSP and HTML

HTML page It is a static page, that is, it is written by the user in advance and placed on the server. The content is fixed and will not change. It is sent to the client by the web server. Most of the web pages that are usually viewed online are based on HTML. linguistic.

The JSP page is a dynamic page generated by the JSP container executing the Java code part of the page in real time, which can dynamically update the content on the page.

Dynamic web pages refer to a web programming technology that is opposite to static web pages. The content of dynamic pages is generally generated by server-side programs. Different people access the page at different times, and the displayed content may be different. After the web designer writes the server-side page program, there is no need for manual control. The page content will automatically change according to the arrangement of the page program.

Static web page, with the generation of html code, the content and display effect of the page will basically not change. No matter who sees the page content at any time. The same, unchanged unless you modify the page code. Static html page files can be opened directly with a local browser.

In short:

• As defined, the HTML page is a static page and can be run directly, and the JSP page is a dynamic page and it runs It needs to be converted into a servlet
• HTML can be opened directly, jsp can only be opened when it is published to a server such as Tomact
• html is a web page writing format standardized by w3c and a unified protocol language ,Static pages. Most of the web pages we look at online are based on HTML language. JSP is a dynamic language based on which JSP can realize all tasks of HTML.

• HTML (Hypertext Markup Language) text markup language, it is a static page, an interpreted language like JavaScript, as long as you have a browser, it can be displayed normally without specifying Compilation tool, just write HTML tags in the TXT document and it can be displayed normally.

  JSP (Java Server Page) is a Java server page, so it is dynamic. It needs to be compiled by JDK and then sent to the client for display. We all know that Java files will be generated after compilation A class file is ultimately executed.

• The header of html is different from that of jsp. This is the header of JSP" " contains the encoding format and dump package in the header. It is also easy to distinguish. You can write Java code by using in jsp, but html does not have .
