将外部jar文件包含到Rhino shell中的资源路径中

Question

资源路径(C:\ti\ccsv5......launcher_1.3.0.v20120522-1813.jar)是我键入-js:>print(system.getproperty（“java.class.path”））时显示的路径；

我不明白如何将jar文件添加到资源路径中，我试图通过命令提示符：java-cp“path of jar”来完成它。包含main的类的名称-->既然Rhino负责从javascripts到类的转换，我如何理解包含main的类的名称？提前谢了。索希尼。

我不认为这个问题与犀牛有特别的关系。相反，这是Linux和Windows系统库之间的区别。

位于https://github.com/twall/JNA/blob/master/www/gettingstartd.md的JNA入门文档提供了以下示例：

package com.sun.jna.examples;

import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.Platform;

/** Simple example of JNA interface mapping and usage. */
public class HelloWorld {

    // This is the standard, stable way of mapping, which supports extensive
    // customization and mapping of Java to native types.

    public interface CLibrary extends Library {
        CLibrary INSTANCE = (CLibrary)
            Native.loadLibrary((Platform.isWindows() ? "msvcrt" : "c"),
                               CLibrary.class);

        void printf(String format, Object... args);
    }

    public static void main(String[] args) {
        CLibrary.INSTANCE.printf("Hello, World\n");
        for (int i=0;i < args.length;i++) {
            CLibrary.INSTANCE.printf("Argument %d: %s\n", i, args[i]);
        }
    }
}

加载的本机库取决于运行程序的平台：对于Windows，您需要使用“MSVCRT”（Microsoft Visual C++运行时）库；对于其他人，使用'C'库。
