【中文标题】无法使用 jinterop 打开 dcom 会话【英文标题】：Can't open a dcom session with jinterop 【发布时间】：2013-04-10 17:17:52 【问题描述】：我正在尝试使用 jinterop 在远程 PC 上运行 wmi 查询，但我什至无法启动 dcom 会话。我知道 wmi 正在工作，因为我可以使用 powershell\wmic\vbscript 毫无问题地访问它。此外，我们的 Windows 客户端已禁用文件共享。
这是我正在尝试的：

JISession dcomSession = JISession.createSession(domain, username, password);
JIComServer comServer;
try
comServer = new JIComServer(valueOf("WbemScripting.SWbemLocator"), hostname, dcomSession);
IJIDispatch wbemLocator = (IJIDispatch) narrowObject(comServer.createInstance().queryInterface(IID));

;
JIVariant results[] = wbemLocator.callMethodA("ConnectServer", params);
IJIDispatch wbemServices = (IJIDispatch) narrowObject(results[0].getObjectAsComObject());
catch (UnknownHostException e)
// TODO Auto-generated catch block
e.printStackTrace();
catch (JIException e)
// TODO Auto-generated catch block
e.printStackTrace();

为什么会抛出 jcifs.smb.SmbException？ WMI 不使用 smb 那么为什么我会看到这个错误？ jinterop 是否要求客户端启用 windows 文件共享？
【问题讨论】：
好吧，我应该对此进行更多研究，但似乎 jinterop 需要在远程 PC 上启动远程注册表，这意味着我无法使用它。但我仍然很好奇文件共享是否是一项要求。 我的经验。当您要使用服务器回调时，必须在客户端启用 jcifs samba 我在使用 prodId 而不是 clsid 时收到此错误。查看 dcom 配置以找到映射。 【参考方案1】：在这个thread中有一个关于这个问题的讨论。
快速总结：
首先，确保已启用远程注册表服务。
其次，确保 j-interop 没有使用自动注册（否则会遇到拒绝访问错误）：
JISystem.setAutoRegisteration(false);
第三，确保防火墙没有干扰。
【讨论】：
【参考方案2】：我正在回复您的声明“我什至无法启动 dcom 会话”。这是使用 j-interop 获取会话的代码。
try
args[0] = "x.y.z.w";
String domain = "";//i am using it as blank
String username = "username";//user who logs in to the system as admin
String password = "password";// used by admin to login to windows pc
JISystem.getLogger().setLevel(Level.FINEST);
JISystem.setInBuiltLogHandler(false);
JISystem.setAutoRegisteration(true);
JISession session3 = JISession.createSession(domain,username,password);
session3.useSessionSecurity(true);
System.out.println(" session3 "+session3);
catch(Exception e)
e.printStackTrace();
你会看到输出 session3 org.jinterop.dcom.core.JISession@a46bc929
