java - 无法使用 jinterop 打开 dcom session

Question

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 session 。我知道 wmi 正在工作，因为我可以使用 powershell\wmic\vbscript 访问它，没有任何问题。此外，我们的 Windows 客户端已禁用文件共享。

这是我正在尝试的:

import static org.jinterop.dcom.impls.JIObjectFactory.narrowObject;
import static org.jinterop.dcom.impls.automation.IJIDispatch.IID;

import java.net.UnknownHostException;

import org.jinterop.dcom.common.JIException;
import org.jinterop.dcom.core.JIComServer;
import org.jinterop.dcom.core.JISession;
import org.jinterop.dcom.impls.automation.IJIDispatch;
import static org.jinterop.dcom.core.JIProgId.valueOf;
import org.jinterop.dcom.core.JIVariant;
import org.jinterop.dcom.core.JIString;

public class SimpleServiceManager {

    public static void main(String[] args) {
        String domain = "mydom";
        String hostname = "remotepc";
        String username = "myusername";
        String password = "mypass";

        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));

            Object[] params = new Object[] {
                    new JIString(hostname),
                    new JIString("ROOT\\CIMV2"),
                    JIVariant.OPTIONAL_PARAM(),
                    JIVariant.OPTIONAL_PARAM(),
                    JIVariant.OPTIONAL_PARAM(),
                    JIVariant.OPTIONAL_PARAM(),
                    new Integer(0),
                    JIVariant.OPTIONAL_PARAM()
            };
            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();
        }
    }
 }

给我这个:

为什么会抛出 jcifs.smb.SmbException？ WMI 不使用 smb 那么为什么我会看到此错误？ jinterop 是否要求客户端启用 Windows 文件共享？

Answer 1

此thread中有关于此问题的讨论.

快速摘要:

首先，确保远程注册表服务已启用。

其次，确保 j-interop 没有使用自动注册(否则您将遇到“访问被拒绝”错误):

JISystem.setAutoRegisteration(false);

第三，确保防火墙没有干扰。
