Introduction
JavaServer Pages (JSP) is a technology for developing web pages that can dynamically generate content. JSP pages are written in HTML and Java code, and they are compiled into servlets by the JSP engine. Servlets are Java programs that run on a web server and generate dynamic content.

Prerequisites
To develop JSP pages in Eclipse, you will need the following:
Eclipse IDE
Java Development Kit (JDK)
Tomcat web server

Creating a JSP Project
To create a new JSP project in Eclipse, follow these steps:1. Open Eclipse and click on the "File" menu.
2. Select "New" and then "Java Project".
3. Enter a name for your project and click on the "Finish" button.
4. Right-click on your project in the Package Explorer and select "New" and then "JSP File".
5. Enter a name for your JSP file and click on the "Finish" button.

Writing JSP Code
JSP code is written in HTML and Java code. The following is a simple example of a JSP page:```

```

The `` directive specifies the Java language, content type, and page encoding for the JSP page. The HTML code is used to create the layout of the page, and the Java code is used to generate dynamic content.

Running a JSP Page
To run a JSP page in Eclipse, follow these steps:1. Right-click on your JSP file in the Package Explorer and select "Run As" and then "Run on Server".
2. Select your Tomcat server from the list and click on the "Run" button.

Your JSP page will open in a web browser. You can view the source code of the page by right-clicking on the page and selecting "View Page Source".Additional Features

JSP pages support a variety of features, including:
Custom tags: Custom tags allow you to create your own reusable JSP components.
Expression language: The expression language is a simple language that you can use to access data and perform operations in JSP pages.
JSTL tags: JSTL tags are a set of standard tags that you can use to perform common tasks in JSP pages.

Conclusion
JSP is a powerful technology for developing dynamic web pages. By using Eclipse and the features described in this tutorial, you can quickly and easily create JSP pages that meet your needs.
