可执行jar无法正常启动

Question

I created an executable jar file with eclipse indigo, but when i double click on it nothing happens. But when i write java -jar c:/dir/filename.jar to cmd, it works. Other jars runs well. I'm using jdk 1.7.0_02 and eclipse indigo. How could i start it normally?

Answer 1

You can run a jar by double clicking it, you just have to make sure that Java is associated with .jar files. The easiest way to do this is by reinstalling the JRE (which generally does it for you).

Otherwise you will need to modify some of your Windows properties (I'm not sure what version of Windows you are running) to point .jar files to the instance of javaw.exe.

Here's a link to a Windows 7 page on how to do it.

Answer 2

右键单击.jar文件并转到属性，然后将“打开方式”程序设置为“ Java SE Binary”。

Answer 3

您可以通过将.jar扩展名与通过javaw.exe运行它的命令相关联来完成此操作。

"C:\Program Files\Java\{java version}\bin\javaw.exe" -jar "%1" %*
