不知道您用的httpclient是什么版本的，我当时用的是httpclient-4.0-alpha3, 我记得NameValuePair应该是用来传递参数的。

HttpPost httpost = new HttpPost("http://127.0.0.1/test.jsp")；

NameValuePair[] nvps = new NameValuePair[] {
new BasicNameValuePair("username", "your username"),
new BasicNameValuePair("password", "your password")
};
httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));

response = httpclient.execute(httpost);
entity = response.getEntity();

比如你想模拟下面这张网页的submit（）方法

<form action='xxx.jsp' method='post'>
 <type input='text' name='username' value='your username'/>
 <type input='text' name='password' value='your password'/>
</form>
... 省略N多，呵呵

当你submit这张网页的时候，username和password会被post到下一张网页。而当你用httpclient去模拟submit方法的时候，你就要构建username和password参数了，NameValuePair就是用来构建这一系列参数的。

请记得对参数进行编码，就是例子中的"your username" 和 "your password"。

httpclient包有很多sample的，应该有提到这个类吧
