雅各布连接到远程计算机的WMI支持
问题描述:
我试图连接到远程计算机使用java和雅各布,以获得有关远程计算机的一些WMI信息。雅各布连接到远程计算机的WMI支持
对于本地主机我使用下面的代码,它工作正常。
String host = "localhost";
String connectStr = String.format("winmgmts:\\\\%s\\root\\CIMV2", host);
ActiveXComponent axWMI = new ActiveXComponent(connectStr);
// other code to get system information
但是,如果我本地主机切换到另一个IP /主机名,我得到了以下错误:
Exception in thread "main" com.jacob.com.ComFailException: Can't find moniker
at com.jacob.com.Dispatch.createInstanceNative(Native Method)
at com.jacob.com.Dispatch.<init>(Dispatch.java:99)
at com.jacob.activeX.ActiveXComponent.<init>(ActiveXComponent.java:58)
at easyticket.classes.WmiExtended.main(WmiExtended.java:28)
,并抛出异常的行是:
ActiveXComponent axWMI = new ActiveXComponent(connectStr);
编辑
我尝试通过使用传递用户名/密码
String host = "192.168.7.106";
ActiveXComponent axWMI = new ActiveXComponent("WbemScripting.SWbemLocator");
axWMI.invoke("ConnectServer", new Variant(host+",\"root\\cimv2\",\"username\",\"password\""));
,但我得到这个错误:
Exception in thread "main" com.jacob.com.ComFailException: Invoke of: ConnectServer
Source: SWbemLocator
Description: The RPC server is unavailable.
我怎样才能解决呢?我如何通过用户名/密码,如果需要域?
我使用的是Windows 8,我试图连接到win8/win7/winxp/win2003server电脑。

某些搜索我设法解决我的问题后...
下面的代码,如果有人需要它。
ActiveXComponent wmi = new ActiveXComponent("WbemScripting.SWbemLocator");
Variant variantParameters[] = new Variant[4];
variantParameters[0] = new Variant(_IPADDRESS);
variantParameters[1] = new Variant("root\\cimv2");
variantParameters[2] = new Variant("username");
variantParameters[3] = new Variant("password");
ActiveXComponent axWMI;
try
{
Variant conRet = wmi.invoke("ConnectServer", variantParameters);
axWMI = new ActiveXComponent(conRet.toDispatch());
}catch(ComFailException e)
{
axWMI = null;
}
if (axWMI == null)
return false;
