JSP簡單練習-用Servlet獲取表單數據

// javaBean代碼
package servlet;

import javax.servlet.*;
import javax.servlet.http.*;

public class AcceptUserRegist extends HttpServlet {
	public String codeToString(String str)  // 處理中文字符串的函數
	{
		String s=str;
		try
		{
			byte tempB[]=s.getBytes("ISO-8859-1");
			s=new String(tempB);
			return s;
		}catch(Exception e)
		{
			return s;
		}
	}
	
	public void init(ServletConfig config) throws ServletException
	{
		super.init(config);
	}
	
	public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{
		// 設置mime
		response.setContentType("text/html;charset=GB2312");
		PrintWriter out=response.getWriter();
		out.println(" ");
		out.println("這是新用戶注冊所提交的數據:
");
		out.println("用戶名是:"+codeToString(request.getParameter("username"))+"
");
		out.println("密碼是:"+codeToString(request.getParameter("userpassword"))+"
