32位应用程序在Eclipse中运行，但在部署之后不能运行。 （没有错误..）

Question

我需要帮助。我正在使用e（fx）clipse在Eclipse中编写Java FX应用程序。我正在使用它的通用build.fxbuild来生成开发我的.EXE文件所需的ant脚本。

该应用程序在Eclipse IDE中完美运行。当使用64位JDK打包时，它甚至可以在部署为.EXE后完美运行。

当我使用32位JDK打包32位安装时出现问题。使用32位JDK，它仍然可以在Eclipse中完美运行。当我创建.EXE时，看似运行正常。问题是......软件使用excel的地址文件，将它们与地址的sql数据库进行比较，然后在SQL数据库中附加带有“ID”建议的excel文件，为客户提供服务我们的数据库中可能存在哪个地址（来自excel）的引用。软件唯一没做的就是附加功能。但是，它会创建XSSFWorkbook，并重新保存工作簿并打开它。所以它得到了这个细分的开始代码，以及结束。但是32位和64位中间正在发生一些事情。

需要帮助！

public static void writeMatchedRecords(XSSFWorkbook wb, HashMap<Integer, ExcelAddress> excelRecords,
        HeaderTemplate template) {

    for (Row row : wb.getSheetAt(0)) {

        if (excelRecords.containsKey(row.getRowNum() + 1)) {

            ExcelAddress excelTemp = excelRecords.get(row.getRowNum() + 1);
            HashMap<Double, ArrayList<ShipTo>> matchedShipTos = excelTemp.getMatchedShipTos();

我遇到了与SWT类似的问题

一般问题是当你需要一些依赖于特定jar的本机函数（如屏幕系统）时。

关于FX的相关讨论：

Creating 32 bit JavaFx Native Bundle in 64 bit machine

https://github.com/javafx-maven-plugin/javafx-maven-plugin/issues/81

Does JavaFX work in 32-bit Windows? (or with a 32-bit JVM)?

我的方式：

1找到JAR

Finding javafx jar file for windows

2在你的app中登上2个罐子

运行时

3，检查32/64

Properties prop=java.lang.System.getProperties();
String 32_64=prop.getProperty("sun.arch.data.model");
// => 32 or 64

4加载＆＃34;好＆＃34; jar在运行时（检查之前已加载）

How should I load Jars dynamically at runtime?
