Java .jar 无法在 Windows 上运行
我正在 Fedora 15 下使用 Eclipse 进行开发。我导出了一个可运行的 jar。它在 Fedora 中运行良好。但我无法在windows上运行它。我已经安装了JRE。我什至尝试安装JDK。没有错误日志，应用程序只是没有启动。
这是输出

I am developing using Eclipse under Fedora 15. I exported a runnable jar. It works fine in Fedora. But I can't run it on windows. I have installed a JRE. I even tried installing JDK. There are no error logs, app just didn't start.
Here's the output

正如 @a_horse_with_no_name 所说“打开命令提示符并运行 java -jar your.jar”。如果它有效，您必须将扩展名 *.jar 映射到名为“java”的程序。这就是 Windows 的工作原理。当双击 *.txt 文件启动记事本时，相同的机制也起作用。
由于我现在在 Linux 上，我无法告诉您如何将扩展名映射到程序，但它位于文件资源管理器菜单中的某个位置。
As @a_horse_with_no_name said "open command prompt and run java -jar your.jar". If it works you have to map extension *.jar to program named "java". This is how windows works. The same mechanism is working when double click on *.txt file starts Notepad.
Since I am on linux now I cannot tell you how to map the extension to program but it is somewhere in menus of file explorer.
它应该是一个可运行的 jar ，因此您可以通过双击在 Windows 上运行它。
it should be a runnable jar , so you can run it on windows using double click.
你可能正在使用绝对路径引用资源..因为你说你是在 Linux 上开发的应用程序。你可能会说
new File("/etc/fstab");.. 这在 Windows 上会失败，因为它没有这样的文件系统。通常情况就是这样。
you may be referencing a resource using absolute path.. since you say you developed the app on Linux. you might have said
new File("/etc/fstab");.. this would fail on windows as it does not have a file system like this.this would usually be the case.
swt dll 有问题。
转到Eclipse安装路径，右键单击eclipse.exe并选择“Properites”。从 eclipse.exe 属性弹出窗口中选择“兼容性”选项卡，然后在选项卡底部选中“权限级别”类别中的以下复选框“以管理员身份运行此程序”。这应该可以解决问题。
There is a problem with swt dlls.
Goto Eclipse installation path, right click on eclipse.exe and select "Properites". From the eclipse.exe Properties pop-up select "Compatibility" tab and at the bottom of the tab check the following check box "Run this program as administrator" in "Previlege Level" category. This should solve the problem.
