jsp表单的提交与显示,我弄的提交后有错误,各位看看!
longin.jsp
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>My Frist JSP Web</title>
<style type="text/css">
  <
  h1 {font: 15pt/17pt "Arial"; font-weight: bold; color:maroon}
  body {
  background-color:#FFFBF0
}
  .STYLE1 {font-size: x-large}
  >
</style>
</head>
<body>
<H1 align="center" class="STYLE1" >欢迎各位光临!</H1>
<form action="logins.jsp" method="post" name="form1">
  <p><center>
  登陆姓名:
  <input name="name" type="text" /></center>
  </p>
  <p><center>
  登陆密码:
  <input name="password" type="password" /></center></p>
  <p><center> 
  <input name="ok" type="submit" value="确认" />    
  <input name="back" type="submit" value="重置" />
  </center>
  </p>
  
</form> 
</body>
</html>
logins.jsp
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>

<body><pre>
<%
String na=request.getParameter("name");
String pa=request.getParameter("password");
if(name==null||password==null)out.println("很抱歉,你没有输入正确!");
  else
 { 
out.println("你的姓名:");
out.println(na);
out.println("您的密码:");
out.println(pa);
  }
%>
</body>
</html>

------解决方案--------------------
String na=request.getParameter("name");
String pa=request.getParameter("password");
if(name==null||password==null)out.println("很抱歉,你没有输入正确!");
改成
Java code
if(na==null||pa==null)
