Java JBoss致命错误:找不到所需的名为JLinkNativeLibrary的本机库 [英] Java JBoss Fatal error: cannot find the required native library named JLinkNativeLibrary

问题描述

我正在尝试使用JBoss与Java Web Application中的Wolfram Mathematica内核一起工作.

I'm trying to work with Wolfram Mathematica Kernel from Java Web Application using JBoss.

这是一个主要班级.

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Main Object时，出现错误.

When I initialize Main Object in Servlet I get an error.

21:30:59,520 ERROR [stderr] (http-/127.0.0.1:8080-2) Fatal error: cannot find the required native library named JLinkNativeLibrary.

推荐答案

该错误表示加载本机库时出现问题. Java具有用于加载本机库的协议，本机库是Windows中的.DLL文件.很有可能它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与之通信.

The error indicates a problem with loading a native library. Java has a protocol for loading native libraries, which are .DLL files in Windows. Most likely it is starting the application using the explicit path in the string and then failing to load some DLL to communicate with it.

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

Make sure the directory with DLLs can be seen by Java (try adding it to the system PATH and restarting the server first): https://www.chilkatsoft.com/java-loadLibrary-Windows.asp
