package mypack;  
import java.io.\*;  
import java.util.\*;  
import javax.servlet.\*;  
import javax.servlet.http.\*;  
public class HelloWorldExample1 extends HttpServlet \{  
public void doGet(HttpServletRequest request,  
HttpServletResponse response)  
throws ServletException, IOException \{  
response.setContentType("text/html;charset=GBK");  
// 第一种情况  
PrintWriter out = response.getWriter();  
out.println("------第一种情况输出中文正常------"+" <br>");  
//第二种情况  
ServletOutputStream out = response.getOutputStream();  
out.println("------第二种情况输出中文报错但输出英文正常------"+" <br>");  
  
\}  
  
\}  
报错如下：  
type Exception report  
  
message  
  
description The server encountered an internal error () that prevented it from fulfilling this request.

===============================================

stream输出的是二进制流 没有对字符进行编码 ： stream 只适用于 ISO 8859-1编码的字符

writer输出的是文本的信息， 是进行过系统编码后的。
