guestbook_jsp.java

这个是一个用JSP做的留言网站的程序

	 GuestQQ=new String(request.getParameter("QQ").getBytes("iso-8859-1"));
		}
		
		String GuestContent=new String(request.getParameter("content").getBytes("iso-8859-1"));

		gb.setGuestName( GuestName );
		gb.setGuestFace(GuestFace);
		gb.setGuestFrom(GuestFrom);
		gb.setGuestTel( GuestTel );
		gb.setGuestEmail(GuestEmail);
		gb.setGuestQQ(GuestQQ);		
		gb.setGuestContent( GuestContent );
		gb.setGuestType(GuestType);
		gb.setUser_id(GuestBook_user_id);//GuestBook_user_id网站变量定义留言板用户 默认0
		gb.add();

		out.println("留言提交成功！！！<br />");
		out.println("此信息将由管理员审核，审核期间不会显示，谢谢！！！<br />");
		out.println("<a href='GuestBook.jsp'>返回</a><br />");
