利用Runtime call操作系统的命令，具体的命令取决于不同的操作系统，注意不要调用Runtime.getRuntime().exec(String)接口，要用Runtime.getRuntime().exec(String[])这个接口，不然复杂命令的执行会有问题。例子如下（拿cpu个数，其他类似）：
目前创新互联已为上千家的企业提供了网站建设、域名、网页空间、网站托管维护、企业网站设计、莫力达网站维护等服务，公司将坚持客户导向、应用为本的策略，正道将秉承"和谐、参与、激情"的文化，与客户和合作伙伴齐心协力一起成长，共同发展。
定义命令：
WindowsCmd ="cmd.exe /c echo %NUMBER_OF_PROCESSORS%";//windows的特殊
SolarisCmd = {"/bin/sh", "-c", "/usr/sbin/psrinfo | wc -l"};
AIXCmd = {"/bin/sh", "-c", "/usr/sbin/lsdev -Cc processor | wc -l"};
HPUXCmd = {"/bin/sh", "-c", "echo \"map\" | /usr/sbin/cstm | grep CPU | wc -l "};
LinuxCmd = {"/bin/sh", "-c", "cat /proc/cpuinfo | grep ^process | wc -l"};
然后判断系统：
os = System.getProperty("os.name").toLowerCase();
根据不同的操作系统call不同的命令。

试试是否可以:)
我是通过一个外部的JAR包来间接来获得DLL文件的句柄 的，它就是jacob了，这是java com brige的简写，呵呵， 这个名称起得非常形象吧，我用的版本是jacob 1.9的，你可以到它的官方网站去下载，下载回来的压缩包中会有两个文件我们需要用到的，一个是jacob.dll,一个是jacob.jar，jacob.dll可以将它复制到系统的system32目录下，而jacob.jar文件，直接将它加入到项目的库中就可以了。这两项准备工作完成后，就可以开始尝试调用了。
新建一个类，引入jacob.jar中的两个类，
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
然后通过dll的ControllerId来读取DLL文件
public class Print {
private ActiveXComponent printController = null;
private Dispatch printObj = null;/*** 默认controllerId的方法*/public Print(){try{printController = new ActiveXComponent(POSControler.Controler);
printObj = (Dispatch)printController.getObject();
}catch(Exception e){
printObj = new Dispatch();
如果方法dll中的方法是空参数时，直接call一下就可以了，如
Dispatch.call(printObj,setDefaultFont);而调用有参数的方法时，则需要将参数在后面依次传入，注意按顺序噢：
一、上Google搜一下Mac及CPU ID的C代码
二、上java.sun.com找那个JNI的指南
三、你用二的方法把一的代码给包一下。
其实利用在java中的runtime来执行在win里面的ipconfig -all的命令可以实现的！！
java.lang.Process proc = Runtime.getRuntime().exec("ipconfig /all");
InputStream istr = proc.getInputStream();
byte[] data = new byte[1024];
istr.read(data);
netdata = new String(data);
分析其中的netdata就是那！，有关cpu的可以类同实现！
1、在远程server里搭建一个http服务，并支持某种服务端语言（如.net或php之类）
2、用服务端语言获取到服务器的磁盘信息，把结果输出
3、在本地用JS写一段AJAX脚本，远程请求服务端写好的程序，得到结果，并展示给用户

使用javascript方式获得客户端的信息主要的优点是,不需求服务器资源.不需求刷新网页.直接在客户端执行脚本获得显示.
在这上找到了硬盘序列号的参数：
\'获得硬盘序列号
Dim cmicWmi As New System.Management.ManagementObjectSearcher(\"SELECT * FROM Win32_DiskDrive\")
Dim Uint32 As UInt32
For Each cmicWmiObj As ManagementObject In cmicWmi.Get
Uint32 = cmicWmiObj(\"signature\")
Next
TextBox1.Text = Uint32.ToString
和在一块总算给提出来了，呵呵。
