在 Windows 上运行 JAR 文件

问题描述：

我有一个名为 helloworld.jar 的 JAR 文件.为了运行它，我在命令行窗口中执行以下命令:

I have a JAR file named helloworld.jar. In order to run it, I'm executing the following command in a command-line window:

java -jar helloworld.jar

这很好用，但是我该如何通过双击来执行它呢?我需要安装任何软件吗?

This works fine, but how do I execute it with double-click instead? Do I need to install any software?

答

最简单的方法可能是升级或重新安装 Java Runtime Environment (JRE).

Easiest route is probably upgrading or re-installing the Java Runtime Environment (JRE).

或者这个:

打开 Windows 资源管理器，从工具中选择文件夹选项..."
单击文件类型"选项卡，向下滚动并选择 JAR 文件类型.
按高级"按钮.
在编辑文件类型"对话框中，选择在操作"框中打开并单击编辑..."
按浏览按钮并导航到 Java 解释器 javaw.exe 的位置.
在Application used to perform action字段中，需要显示类似C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe" -jar "%1" %(注意:以javaw"开头的部分必须完全相同；路径名的另一部分可能会因您使用的 Java 版本而异)然后按 OK 按钮直到所有对话框都关闭.

Open the Windows Explorer, from the Tools select 'Folder Options...'
Click the File Types tab, scroll down and select JAR File type.
Press the Advanced button.
In the Edit File Type dialog box, select open in Actions box and click Edit...
Press the Browse button and navigate to the location the Java interpreter javaw.exe.
In the Application used to perform action field, needs to display something similar to C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe" -jar "%1" % (Note: the part starting with 'javaw' must be exactly like that; the other part of the path name can vary depending on which version of Java you're using) then press the OK buttons until all the dialogs are closed.
