JNI-WMI连接错误

我有一个java Web应用程序来从本地和远程windows机器收集一些数据。我正在使用wmi连接连接到计算机。 我使用tomcat作为Web服务器。对于wmi连接,我编写了c++代码,并使用JNI连接java和c++。当我启动服务器并输入登录详细信息时,tomcat崩溃了。

日志文件中的错误为。。

#

我使用的是tomcat 8.5.28和jdk1.8.0\u 162

下面是我的java代码:Verify\uu0。Java语言

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;

public class Verify_ extends HttpServlet{

public native int connect();

public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
    System.loadLibrary("Verify_");
    Verify_ verify = new Verify_();

    response.setContentType("text/html");

    PrintWriter out = response.getWriter();

    String ServerName   = request.getParameter("servername");
    String UserName     = request.getParameter("username");
    String Password     = request.getParameter("password");

    int status = verify.connect();

    if(status == 0)
        out.println("Connected to " + ServerName);

    else if(status == 1)
        out.println("failed to initialize CoInitializeEx");

    else if(status == 2)
        out.println("failed to initialize CoInitializeSecurity");

    else if(status == 3)
        out.println("failed to initialize CoCreateInstance");

    else if(status == 4)
        out.println("failed to connect to Server");

    else
        out.println(status);
}

public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
    doGet(request,response);
}}

以下是JNI接口代码:Verify\uu0。h类

我已经试了5天了。请帮帮我。如果还有别的办法,告诉我。。

提前感谢
