1. 定义一个用于输出JavaScript代码 的Servlet类。
package com.mycompany.response.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServle ......
JDK6已经发布很久了，很早就听过他已经支持脚本语言了，不过一直没有时间尝试，今天偷闲试了一下，感觉不错。
javax.script包它是Java新增的操作脚本的工具包，
利用它我们可以对脚本语言进行操作（本例仅是针对javascript
