Question

我正在创建一个应该在Windows和OSX系统中都能运行的应用程序。当我在OSX上完成开发和测试时，我终于导出了一个Runnable Jar文件，它运行得很好。但当我让它在另一台机器（Windows）上运行时，它抛出了异常。我不是100％确定问题是什么，但我相信它正在使用一些Eclipse的lib或者其他东西，因为如果我让项目在Windows机器上运行Eclipse，它也可以运行。

我试图绕着manifest.mf试图自己生成一个Runnable Jar，但到目前为止我还没有工作过。

这是Runnable JAR导出生成的内容：

Manifest-Version: 1.0
Rsrc-Class-Path: ./ poi-3.12.jar commons-validator-1.4.1.jar javaxt-co
 re.jar gson-2.3.1.jar mysql-connector-java-5.1.36-bin.jar ojdbc6.jar 
 commons-net-3.3.jar commons-imaging-1.0.jar imgscalr-lib-4.2.jar comm
 ons-io-2.4.jar jai_imageio-1.1.jar
Class-Path: .
Rsrc-Main-Class: br.com.inforsec.GeotagImages.GeotagImages
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader

然后我尝试混合了一些我发现的论坛，但我不太明白：

Manifest-Version: 1.0
Rsrc-Class-Path: ./ poi-3.12.jar commons-validator-1.4.1.jar javaxt-co
 re.jar gson-2.3.1.jar mysql-connector-java-5.1.36-bin.jar ojdbc6.jar 
 commons-net-3.3.jar commons-imaging-1.0.jar imgscalr-lib-4.2.jar comm
 ons-io-2.4.jar jai_imageio-1.1.jar
Class-Path: .
Rsrc-Main-Class: br.com.inforsec.GeotagImages.GeotagImages
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader
Name: br/com/inforsec/GeotagImages/
Specification-Title: Georeference Tag Images
Specification-Version: 0.7
Specification-Vendor: Inforsec Ltda.
Implementation-Title: br.com.inforsec.GeotagImages 
Implementation-Version: build07
Implementation-Vendor: Inforsec Ltda.

嗯，它不起作用，我对如何解决它感到很失望。

以下是我正在尝试阅读图片的片段：

public class Image {
    private String path;
    private File file;

    public Image(String path){

        GeotagImages.LOG.println("Image: Starting");

        this.path = path;
        File imageFile = new File(path);
        GeotagImages.LOG.println("Image: path = " + path);
        javaxt.io.Image image = new javaxt.io.Image(imageFile);
        this.file = new File(path);
    . . .

例外是第41行抛出：

javaxt.io.Image image = new javaxt.io.Image(imageFile);

在Eclipse中运行程序工作正常，但jar不行
