我可以通过cmd运行.jar文件，但我无法双击它们 [英] I can run .jar files through cmd, but I cannot double click them

问题描述

首先，我正在学习Java，但我仍然很新，所以复杂的代码将会超出我的想象。

First, I am studying Java, but I am still very new to it, so complicated code will go over my head.

当我下载.jar文件时说安装一个mod到我的世界并双击它，它不会运行。装载轮持续两秒钟然后停止，没有其他任何事情发生。我知道的.jar设置正确，因为它使用命令运行cmd

When I download a .jar file to say install a mod to minecraft and double click it, it doesn't run. The loading wheel goes for like two seconds and then stops, and nothing else happens. The .jar I know is set up right because it runs through cmd with the command

    cd "wherever the file is"
    java -jar "file name".jar

所以我已经尝试用它来运行它默认程序设置为java \jdk1.7.0_25 \ jre \ bin中的javaw.exe。没有任何反应。因此文件关联设置在正确的位置。我在这里不知所措。

So I've already tried to run it with the default program set as javaw.exe in the java\jdk1.7.0_25\jre\bin. Same where nothing happens. So the file association is set to the right place. I am at a loss here.

因为我仍然可以通过cmd运行它们，所以它并没有那么糟糕，但是当我到书中关于罐子的部分时，我希望能够通过Windows资源管理器GUI运行它，这就像使用我可以看到的.jar文件的一半好处。

It isn't so bad since I can still run them through cmd, but when I get to the part in the book about jars, I want to be able to run it through the Windows Explorer GUI, which is like half the benefit of using .jar files that I can see.

是否可能是注册表错误？我已经看到了很多关于这个问题的问题，但是大多数问题似乎都是设置.jar的问题，我没有这样做，而且我认为不是这样的。

Is it possibly a registry error? I have seen a lot of questions specifically about this problem, but most of them it seems were problems with setting up the .jar, which I didn't do, and I don't think that is the case here.

我有Windows Vista 64位。

I have Windows Vista 64bit.

如果我不够具体，请随时询问。

If I wasn't specific enough, feel free to ask.

推荐答案

我遇到了同样的问题，结果是注册表中的.jar文件关联被破坏了。以下步骤修复了它：

I had the same problem, and it turns out that the .jar file association in the registry was broken. The following steps fixed it:

打开注册表编辑器，然后导航到HKEY_CLASSES_ROOT\jarfile\shell\open \命令。修改Default键的值，如下所示：
[JRE的位置] \bin\javaw.exe-jar％1％*

替换[你的位置] JRE]与JRE安装的根目录。

例如：

C：\Program Files\Java\jre7\bin\javaw.exe-jar％1％*

对HKEY_LOCAL_MACHINE \ SOFTWARE \Classes \ jarfile \ shell \ openn \命令重复上述步骤。

Open the Registry Editor, and navigate to HKEY_CLASSES_ROOT\jarfile\shell\open\command. Modify the value of the Default key as follows: "[Location of your JRE]\bin\javaw.exe" -jar "%1" %*
Replace [Location of your JRE] with the root directory of your JRE installation.
For example:
"C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*
Repeat the above steps for HKEY_LOCAL_MACHINE\SOFTWARE\Classes\jarfile\shell\open\command.

我有一台Windows 7机器，但我认为这也适用于32位环境。

I have a Windows 7 machine, but I assume this would work for 32-bit environments as well.

编辑：修复了示例中的路径 - 它应该使用Program Files目录而不是程序文件（x86）。

Fixed the path in the example - it should use the "Program Files" directory and not "Program Files (x86)".
