以web形式运行出错:java.io.CharConversionException:No an ISO 8859-1 character:以

public void doPost(HttpServletRequest request,
 HttpServletResponse response)
 throws ServletException, IOException {
 try{
 response.setContentType("text/html;charset=GB2312");
 new BusinessService().test(this.getServletContext(),response.getOutputStream());
 }catch(Exception e){e.printStackTrace();
}

out.println("------以下是"+customer.getName()+"的个人信息------"+" ");
 out.println("ID: "+customer.getId()+" ");
 out.println("口令: "+customer.getPassword()+" ");
 out.println("E-Mail: "+customer.getEmail()+" ");
 out.println("电话: "+customer.getPhone()+" ");
 out.println("地址: "+customer.getAddress()+" ");
 String sex=customer.getSex()=='M'? "男":"女";
 out.println("性别: "+sex+" ");
 String marriedStatus=customer.isMarried()? "已婚":"未婚";
 out.println("婚姻状况: "+marriedStatus+" ");
 out.println("生日: "+customer.getBirthday()+" ");
 out.println("注册时间: "+customer.getRegisteredTime()+" ");
 out.println("自我介绍: "+customer.getDescription()+" ");
 out.println("<img src='photo_copy.gif' border=0>");

这样改了可行：

private void printCustomer(ServletContext context,ServletOutputStream out,Customer customer)throws Exception{
    //save photo
    byte[] buffer=customer.getImage();
    String path=context.getRealPath("/");
    FileOutputStream fout=new FileOutputStream(path+"photo_copy.gif");
    fout.write(buffer);
    fout.close();


     OutputStreamWriter ow = new OutputStreamWriter(out,"GB2312");

ow.write("------以下是"+customer.getName()+"的个人信息------"+" ");
 ow.write("ID: "+customer.getId()+" ");
 ow.write("口令: "+customer.getPassword()+" ");
 ow.write("E-Mail: "+customer.getEmail()+" ");
 ow.write("电话: "+customer.getPhone()+" ");
 ow.write("地址: "+customer.getAddress()+" ");
 String sex=customer.getSex()=='M'? "男":"女";
 ow.write("性别: "+sex+" ");
 String marriedStatus=customer.isMarried()? "已婚":"未婚";
 ow.write("婚姻状况: "+marriedStatus+" ");
 ow.write("生日: "+customer.getBirthday()+" ");
 ow.write("注册时间: "+customer.getRegisteredTime()+" ");
 ow.write("自我介绍: "+customer.getDescription()+" ");
 ow.write("<img src='photo_copy.gif' border=0>");

 ow.flush() ;//不能少
 ow.close() ;

}
