调用方法时出错。并且无法启动JVM - Native Package将构建但不会启动

标签: javafx deployment ant jvm package

任何人都可以更明确地说明问题所在的位置,以及如何解决问题?

我正在跑步:

  • Windows 7
  • Eclipse Mars.2发布(4.5.2)

我已经仔细地按照说明仔细阅读了关于code.makery.ch的Marco教程(code.makery.ch/library/javafx-8-tutorial/part7 /)

我之前已部署此程序的早期原生包,但有些麻烦,但最终成功添加后

-vm
C:\Program Files\Java\jdk1.8.0_91\bin\javaw.exe

到eclipse.ini

最终让ant build成功运行后,

do-deploy:

我的主文件如下所示:

public class Main extends Application {
    public static FXMLLoader loader;

    //Icon from https://icons8.com

    @Override
    public void start(Stage primaryStage) throws Exception{
        loader = new FXMLLoader();
        loader.setLocation(Main.class.getResource("view/Arrivals_Layout1.fxml"));
        Parent root = loader.load();
        primaryStage.getIcons().add(new Image(ClassLoader.getSystemResourceAsStream("resources/images/Pallet-96.png")));
        primaryStage.getIcons().add(new Image(ClassLoader.getSystemResourceAsStream("resources/images/pallet_96_allsizes.ico")));



        primaryStage.setTitle("Purchase Order Arrivals");
        primaryStage.setScene(new Scene(root));
        primaryStage.setMinWidth(820);
        primaryStage.setMinHeight(375);
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

如果有帮助,我的Package Explorer看起来像this 我的路径:C:\ProgramData\Oracle\Java\javapath;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\IBM\Client Access\Emulator;C:\Program Files (x86)\IBM\Client Access\Shared;C:\Program Files (x86)\IBM\Client Access\;C:\Program Files\Microsoft SQL Server\110\DTS\Binn\;C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\ManagementStudio\;C:\Program Files (x86)\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files\Microsoft SQL Server\110\Tools\Binn\;C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\PrivateAssemblies\;C:\Program Files (x86)\Microsoft SQL Server\110\DTS\Binn\;C:\Program Files\TortoiseHg\;C:\Program Files (x86)\Inno Setup 5

生成.exe并将程序安装在/ AppData中。

该程序将在Eclipse中编译并运行良好,但是当我运行已安装的版本时,我得到:

  

调用方法时出错。

首先

然后单击确定

  

无法启动JVM

我似乎尝试了一切:

我已经阅读过多个类似的问题,并且已经浏览过互联网,但还没有发现这个问题。我读过的许多例子含糊不清或没有答案:

因为他在部署方面不那么精通,所以Marco自己说要问Stack Exchange的强大世界: http://code.makery.ch/library/javafx-8-tutorial/part7/#comment-2233862311

再次说明我的问题所处的具体问题,以及如何解决问题?

1 个答案:

答案 0 :(得分:3)

我明白了!

我发现问题的方式:

经过双重,三重检查依赖关系并看到它编译后再构建好,我怀疑jar文件位于build/deploy/{yourProjectName}.jar

编辑:如果您只在安装错误后才收到错误,那么在安装目录中运行jar是有意义的。 (AppData/Local/{ApplicationTitle}/app/{yourProjectName}.jar

我在命令行上运行它以查看它是否抛出异常:

轻松导航到我记下的目录,我在Explorer中保存了项目,然后将其复制到命令行。

  1. 打开命令提示符

    + r

    cmd + 输入

  2. 导航到目录

    cd {ProjectPath}\build\deploy

  3. 运行jar文件

    java -jar "{YourJar}.jar"

  4. 因为我是通过命令提示符执行jar的,所以java有一个地方可以向我显示异常!

    C:\Users\administrator.SUNDANCE\IdeaProjects\PODTester_Layout8\build\deploy>java
     -jar "PODTester_Layout8.jar"
    java.io.FileNotFoundException: src\resources\Carrier List.txt (The system cannot
     find the path specified)
            at java.io.FileInputStream.open0(Native Method)
            at java.io.FileInputStream.open(Unknown Source)
            at java.io.FileInputStream.<init>(Unknown Source)
            at java.io.FileInputStream.<init>(Unknown Source)
            at java.io.FileReader.<init>(Unknown Source)
    

    在审核我的代码后,由于明确引用src,我认为它没有找到该文件。我解决了这个问题,看哪!重建后,已安装的应用程序正常运行!

    总结如下:

    如果您的原生套餐会抛出

      

    调用方法时出错。

      

    无法启动JVM

    通过命令提示符运行您的jar文件,看它是否会引发异常。

    现在,如果您想了解我的具体问题以及我修复过程的详细信息,请点击此处:

    问题:

    我认为它可能与依赖关系有关(特别是对我来说包括sqljdbc驱动程序),但事实证明它不是一个依赖问题。问题是 .jar只在安装时抛出了一个例外是什么让错误如此难以理解的是哦,如此通用&#34;无法调用方法。&#34;这给了我很少的新信息。

    为了缓解未来类似问题,我添加了showExceptionDialog()方法(受Marco Jacob's work启发):

    /**
     * Shows a dialog box when an exception occurs instead of just doing nothing.
     *
     * Once installed this will help to diagnose problems instead of letting
     * them go unnoticed.
     *
     * @param e the exception to print; it's stacktrace will be shown as well
     */
    public static void showExceptionDialog(Exception e) {
        Alert alert = new Alert(Alert.AlertType.ERROR);
    
        alert.setTitle("Exception Dialog");
        alert.setHeaderText("An error occurred:");
    
        String content = "Error: ";
        if (null != e) {
            content += e.toString() + "\n\n";
        }
    
        alert.setContentText(content);
    
        Exception ex = new Exception(e);
    
        //Create expandable Exception.
        StringWriter sw = new StringWriter();
        PrintWriter pw = new PrintWriter(sw);
        ex.printStackTrace(pw);
    
        String exceptionText = sw.toString();
    
        //Set up TextArea
        TextArea textArea = new TextArea(exceptionText);
        textArea.setEditable(false);
        textArea.setWrapText(true);
    
    
        textArea.setPrefHeight(600);
        textArea.setPrefWidth(800);
    
    
        //Set expandable Exception into the dialog pane.
        alert.getDialogPane().setExpandableContent(textArea);
    
    
        alert.showAndWait();
    }
    

    关于我的问题的具体细节:

    在我的程序中,我有一个名为Carrier List.txt的文件被读取和写入,并存储在resources文件夹中。

    在IntelliJ和Eclipse中,它编译得很好,因为它可以很好地找到src/resources/Carrier List.txt。当按照Marco Jacob's Deployment Tutorial手动复制资源文件夹时,情况会很好,但我明确引用了

      

    src / resources / Carrier List.txt

    在我的代码中,而不仅仅是

      

    resources / Carrier List.txt
