Java JBoss Fatal error: cannot find the required native library named JLinkNativeLibrary

Question

我正在尝试使用 JBoss 的 Java Web 应用程序使用 Wolfram Mathematica 内核。

这是主菜 Class。

public class Main {

 static KernelLink ml;
 static KernelLink ml2;

 public Main(){
    String path = "-linkmode launch -linkname 'C:/Program Files/Wolfram Research/Mathematica/9.0/MathKernel.exe'";
    try {

        ml = MathLinkFactory.createKernelLink(path);// подключаем ядро
        ml.setComplexClass(MyComplex.class);

        System.out.println(ml.getComplexClass());
        ml.discardAnswer();
        ml.evaluate("<<hexagon.m");
        ml.discardAnswer();


    }
    catch (Exception e){
        System.out.println(e.toString());
    }
}
}

当我在 Servlet 中初始化主对象时出现错误。

Answer 1

该错误表示加载本机库时出现问题。 Java 有一个加载本机库的协议，这些库是 Windows 中的 .DLL 文件。它很可能是使用字符串中的显式路径启动应用程序，然后无法加载某些 DLL 以与之通信。

确保Java可以看到包含DLL的目录（尝试将其添加到系统PATH并先重新启动服务器）： https://www.chilkatsoft.com/java-loadLibrary-Windows.asp
