Question

我正在开发的Java应用程序是其他人用来帮助我们日常活动的内部工具。使用该工具时（在调用下面代码的JButton印刷机上）我希望它打开一个新的Outlook电子邮件，供用户查看/编辑。

起初我是在64位Eclipse中开发这个应用程序，尽管我进行了所有研究，但无法让SWT打开Outlook。在我遇到一些运行64位与32位SWT的问题之后，我有了检查Outlook的想法，并且确定公司使用的是32位。我加载了32位eclipse，导入了我的项目，将SWT切换到32位，它完全符合预期。

我注意到正在运行的进程是javaw.exe * 32但是64位Eclipse正在使用进程javaw.exe。我从32位Eclipse中导出JAR并给它一个镜头，没有出现EMail。我检查了安装的JRE并看到了32位和64位，但我公司的策略只强制Java控制面板中的64位JRE。我和其他人一起工作，并且看到here已经安装并启用了。 JAR仍无法打开电子邮件。我甚至尝试禁用64位，它仍然无法正常工作。

有什么办法可以解决这种情况吗？如果我能更好地阐述或提供更多信息，请告诉我！

没有必要使用重量级和难以使用的Ole类。如果您只想发送电子邮件，请拨打以下电话：

Program.launch("mailto:bla@blubb.com&subject=Subject&body=Me‌ssage here");

这适用于所有体系结构和操作系统。

为什么我无法在Eclipse中使用JAR在64位系统上打开32位Outlook ...？
