[英]JAR compiled on 64 bit Windows wont run on 32 bit

原文 2012-09-05 19:06:26 9 3 java/ windows/ jar/ 32bit-64bit

I have just developed and exported a Runnable JAR using Eclipse on my 64 Bit Windows 7 Laptop. 我刚刚在64位Windows 7笔记本电脑上使用Eclipse开发并导出了一个Runnable JAR。 I have just been trying it on other computers and it works on another Windows 7 x64 laptop when you double click it. 我刚刚在其他计算机上尝试过，当你双击它时，它可以在另一台Windows 7 x64笔记本电脑上运行。 However, on a 32 Bit laptop I have in only starts if I run it from command line using java -jar "C:\\Name of Jar.jar" but throws no errors whatsoever. 但是，在32位笔记本电脑上，如果我使用java -jar "C:\\Name of Jar.jar"从命令行运行它，我只能启动它，但不会抛出任何错误。

Furthermore though, if I use the command javaw "C:\\Name Of Jar.jar" I get an error message saying "Could not find the main class C:\\Name of Jar.jar. Program will exit." 此外，如果我使用命令javaw "C:\\Name Of Jar.jar"我收到一条错误消息“无法找到主要类C：\\ Jar.jar的名称。程序将退出。”

Does anybody know why, and how to fix it? 有人知道为什么，以及如何解决它？ Thanks in advance 提前致谢

3 个解决方案

Did you build it with JDK 1.7? 你用JDK 1.7构建它了吗？ Maybe you haven't installed JRE7 on the pc you try to run it. 也许您没有在尝试运行它的PC上安装JRE7。 It's an odd bug I encountered several times. 这是我遇到过几次奇怪的错误。

On your 32-bit machine right-click -> Open With on the JAR. 在32位计算机上右键单击 - >在JAR上打开。 If a JRE is listed, you can open with it, and make it the default program to run with. 如果列出了JRE，则可以使用它打开，并使其成为运行的默认程序。

I don't think it has to do with the 32 or 64-bit OS. 我不认为它与32位或64位操作系统有关。

Try javaw -jar jar_name . 试试javaw -jar jar_name 。 I think that might do the trick. 我认为这可能会成功。
