在Servlet里如何读取和设置Cookie?（分数全部给出！）(35分)

麻烦各位高手给个简单的例子，多谢啦！

参考：
用类javax.servlet.http.Cookie（j2se里面没有，在j2ee里面）应该可以吧，
不过我没有用过，你自己看JavaDoc，试试看。

Source Code for Cookie Example
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class CookieExample extends HttpServlet {
public voiddo
Get(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();

// print out cookies
Cookie[] cookies = request.getCookies();
for (int i = 0;
i < cookies.length;
i++) {
Cookie c = cookies;
String name = c.getName();
String value = c.getValue();
out.println(name + " = " + value);
}
// set a cookie
String name = request.getParameter("cookieName");
if (name != null &amp;&amp;
name.length() > 0) {
String value = request.getParameter("cookieValue");
Cookie c = new Cookie(name, value);
response.addCookie(c);
}
}
}

为什么不用Session,另外建议下在几本jdk, servlet的chm的帮助文档，用google搜即可

接受答案了.
