How to use JSP with HTML

With the continuous development of Internet technology, Web development has become an important field in today's IT industry. As one of the common Web development technologies, JSP has good flexibility and scalability and is widely used in the development of modern Web applications. This article will discuss how JSP is used in conjunction with HTML.

1. Introduction

JSP (Java Server Pages) is a Web development technology based on the Java language. It makes full use of the powerful features of Java and is closely integrated with HTML. . JSP technology uses JSP tags as defining elements and embeds Java code into HTML pages to achieve powerful dynamic Web page generation capabilities.

HTML (Hyper Text Markup Language) is a standard language used to create Web pages. Unlike JSP, HTML is a static language that can only display pages. Therefore, in order to realize the dynamics of Web pages, JSP technology needs to be used to add dynamic content to HTML pages.

2. The difference between JSP and HTML

The biggest difference between JSP and HTML is their different functions. HTML is just a standard language for representing Web pages, while JSP not only has all the functions of HTML, but can also dynamically generate Web page content from the server side.

JSP technology allows Java code to be embedded into HTML pages, using JSP tags to distinguish HTML pages. Where dynamic content needs to be added, JSP tags can be used to generate dynamic content, including querying data from the database, integrating JavaBean objects, using Java API, etc. In addition, JSP tags can also handle operations such as form data, redirection, and error handling, which cannot be achieved through HTML language.

3. How to combine JSP and HTML

To achieve the combination of JSP and HTML, you need to follow the following steps:

(1) Create an HTML page

First, we need to create an HTML page to display the content of the Web page. In HTML pages, JSP tags need to be used to identify content that needs to be dynamically generated, such as headers, toolbars, content areas, and page footers. In the identified area, JSP tags need to be used to embed Java code to generate dynamic Web pages.

(2) Create a JSP page

Next, you need to create a JSP page to process dynamic content in the HTML page. In JSP pages, you can use JSP tags and JAVA code to generate dynamic content.

(3) Embed the JSP page into the HTML page

Finally, you need to embed the JSP page into the HTML page to integrate dynamic content into the HTML page. Embed the JSP page in the HTML page through the following code:

<jsp:include page="example.jsp" />

where example.jsp is the name of the JSP page that needs to be embedded. Through the above code, dynamic content can be embedded into HTML pages, thus realizing the combined use of JSP and HTML.

4. Conclusion

The combined use of JSP and HTML can greatly improve the dynamics and scalability of Web pages, making Web applications more flexible and easier to maintain. This article introduces the differences and combination methods of JSP and HTML. I hope it will be helpful to readers and help them better understand and apply this technology.
