So in eclipse when you generate a .jsp file it automatically includes the following top line:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>

Is there a way to also include javascript code so that I can have some of the file written in java and some written in javascript?

• java
• javascript
• html
• jsp

• 1 Um, include an external JavaScript file? Do you realize that Java and JavaScript do not run at the same time? – epascarello Commented Mar 15, 2013 at 2:21

Usually I include my JavaScript in JSP like this:

<script type="text/javascript" src="js/script.js"></script>

This way I can minimize the js code and also cache it differently than JSP files in Tomcat.

The answer is Yes, you can add the js in jsp. And this also has benefit. It helps you to use the values stored in request and session, because the js code which contains the jsp stuff in jsp will be piled while the *.js file will not. And also you should keep in mind that you'd better put the js code in .js file not in jsp, so the browser doesn't need to load it repeatly and code seems more clear, also good for debug. Another answer has give you the example code to import js file, so I just ignore it.
