怎么发送数据到服务器端啊？

[知行职场-雷曼]

我服务器是用的tomcat,用java写服务器端程序。

xml发送时总是服务器收不到username和password.


xml程序如下：

<?xml version="1.0" encoding="GB2312"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.CNJM.NET">
<wml>
<card ordered="false">
<do type="accept">
<go href="../games/servlet/Register" method="post">
<postfield name="username" value="$username"/>
<postfield name="password" value="$password"/>
</go>
</do>
<p>
<fieldset title="Name">
用户名称:
<input name="username" maxlength="10" emptyok="false"/><br/>
口令:
<input name="password" maxlength="10" emptyok="true"/><br/>

</fieldset>

</card>
</wml>

还是不行啊!
我服务器的JAVA是这样写的

String strUsername = null, strPSW = null, strCellPhone = null;
strUsername = request.getParameter("username");
strPSW = request.getParameter("password");
strCellPhone = request.getParameter("cellphone");
System.out.println(request.getRequestURI());

SQLOperator sqlOperator = new SQLOperator();
System.out.println(strUsername + ":" + strPSW);

boolean bRet;
if (CheckUserInfo(strUsername, strPSW, strCellPhone))
{
bRet = sqlOperator.AddUser(strUsername, strPSW, strCellPhone);
}



服务器端有什么问题吗？
