Java如是获得客户端Mac地址? 而不是本机的Mac地址
我是用Liunx来开发Java的,现在要开发一个获取客户端Mac的需求,我网上找了一些代码都是能得到本机的MAC地址,而不是客户端的MAC地址,哪位大哥,帮帮忙,看看改改程序,能不能变成客户端执行服务端就能获得客户端MAC地址,谢谢了~

[解决办法]

<script language="JScript" event=OnObjectReady(objObject,objAsyncContext) for="someaddr">
            if(objObject.IPEnabled != null && objObject.IPEnabled != "undefined" && objObject.IPEnabled == true)
            {
            if(objObject.MACAddress != null && objObject.MACAddress != "undefined")
            MACAddr = objObject.MACAddress;
            if(objObject.IPEnabled && objObject.IPAddress(0) != null && objObject.IPAddress(0) != "undefined")
            IPAddr = objObject.IPAddress(0);
            if(objObject.DNSHostName != null && objObject.DNSHostName != "undefined")
            sDNSName = objObject.DNSHostName; 
 
            }
        </script>

        <script type="text/javascript" event="OnCompleted(hResult,pErrorObject, pAsyncContext)" for="someaddr">
        var hidMacString=unescape(MACAddr);
        var hidMac=hidMacString.replace(/:/g,"-");
            document.getElementById('hidMac').value=hidMac ;
            </script>

里面的hidMac就是mac地址

可能需要设置下浏览器的安全级别
