</blockquote>

And jar files still fail to open (in my case it was like I never double clicked): 
open the Command Prompt (to be safe with admin rights enabled) and type the following commands:

<code>java -version</code> This should return a version so you can safely assume java is installed.

Then run

<code>java -jar "PATHTOFILE\FILENAME.JAR"</code>

Read through the output generated. You may discover an error message.

blocks|key|3802570|text|这不是文件关联问题，因为您可以通过命令行正确启动应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3802571|问题是，当您双击关联的文件时，应用程序启动和运行时将该文件的路径作为基本执行路径。任何相对路径都将从文件路径中计算出来，并且您尝试加载的所有内容可能都会丢失。|3802572|即使您用try/catch(异常)包围了所有入口点代码，也没有发生任何事情，因为java抛出了Throwables而不是Exception+:要在java入口点中解决这个问题，请使用try/catch(Throwable)+(用于异常和错误的基类)和debug来包围main方法的内容。|3802573|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

It's not a file association problem since you can launch the application correctly through command line.

The problem is when you double click on an associated file the application starts and runs with the file's path as base execution path. Any relative path will be computed from the file path and everything you try to load will probably be missing.

Nothing happens, even if you surround all of your entry point code with try/catch(Exception) because java s throwing Throwables and not Exceptions: to fix this in your java entry point surround the content of the main method with a try/catch(Throwable) (base class for Exception and Error) and debug.

change the default application for JAR files from java.exe to javaw.exe from your JAVA_HOME/bin folder.

This is because, java.exe is console application only, but JAR file needs a window rendered execution. Since javaw.exe is a window application, it is preferred for the execution of JAR files.

An alternative to this is that to some extent you can use command prompt to run your JAR files by simply using java keyword with -jar attrib.

I tried all above steps to resolve the problem but nothing worked. I had installed both JDK and JRE.

In my case, one jar file was being opened by double click while other was not being opened. I examined those files and the probable reason was that which was being opened, was created using JAVA SE 6 and the one not being opened was created using JAVA SE 7. Although, the problematic jar file was being run via command prompt (java -jar myfile.jar).

I tried Right Click -> Properties -> Change to javaw.exe with both in JDK\bin directory and JRE\bin directory.

I was finally able to fix the problem by changing javaw.exe path (from JDK\bin to JRE\bin) in registry editor.

Go to HKEY_CLASSES_ROOT\jarfile\shell\open\command, the value was,

<pre><code>"C:\Program Files\Java\jdk-11.0.1\bin\javaw.exe" -jar "%1" %*
</code></pre>

I changed it to,

<pre><code>"C:\Program Files\Java\jre1.8.0_191\bin\javaw.exe" -jar "%1" %*
</code></pre>

and it worked. Now the jar file can be opened by double click.

blocks|key|3802894|text|我也遇到了同样的问题，我在互联网上搜索了解决方案，没有一个建议不是通过双击.jar文件打开的。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3802895|在我的例子中，原因是我的计算机上安装了多个JDK和JRE版本。由于我是一名软件开发人员，为不同的客户机使用多个不同的版本，因此我需要在我的PC+(Windows10Pro)中使用多个JDK。因此，我不想更改系统变量(即JAVA_HOME、JRE_HOME或PATH)，而是每当我想使用不同的版本时，我都会使用命令提示符在用户进程中运行java。|3802896|安装JDK时，它会注册与我们在PC上安装的最新版本相关联的.jar文件。如果您右键单击.jar图标并选择属性，它将显示该文件打开时带有“Java+SE+Binary”。如果我们查看注册表项：HKEY_CLASSES_ROOT\jarfile\shell\open\command，它将指向最新的JDK版本。|3802897|这不是一个好主意(有时令人讨厌)，每次我想要运行一个不同版本的应用程序构建时更改注册表项。|3802898|因此，在我的情况下，不可能只双击.jar文件来执行它。但相反，我自己找到了一个解决方案。|3802899|场景：|BOLD|3802900|PC上安装了多个JDK+(1.7、1.8、9.0、10.0、11.0和12.0+)，因此最新安装的是12.0。|3802901|Problem|3802902|我想双击一个使用JDK1.8开发但不起作用的可执行.jar|3802903|这是我围绕解决方案所做的工作：|3802904|3802905|为要打开的.jar文件创建快捷方式。|ordered-list-item|3802906|右键单击快捷方式图标，然后选择属性->快捷方式选项卡|3802907|将目标中的文本(例如"D:\Dev\JavaApp1.8.jar")更改为|3802908|3802909|"C:\Program+Files\Java\jdk1.8.0\bin\javaw.exe“-jar+"D:\Dev\JavaApp1.8.jar”|3802910|然后单击确定双击快捷方式。|unordered-list-item|3802911|3802912|它现在应该会打开应用程序。|3802913|entityMap^0|11|4|0|31|9|3B|8|3K|4|0|T|4|2N|18|0|0|G|4|0|0|3|0|0|0|7|0|P|4|0|0|0|5|4|0|0|A|N|0|0|1|18|1A|4|1G|L|0|0|0|0^^$0|@$1|2|3|4|5|6|7|1H|8|@$9|1I|A|1J|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|1K|8|@$9|1L|A|1M|B|C]|$9|1N|A|1O|B|C]|$9|1P|A|1Q|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|1R|8|@$9|1S|A|1T|B|C]|$9|1U|A|1V|B|C]]|D|@]|E|$]]|$1|J|3|K|5|6|7|1W|8|@]|D|@]|E|$]]|$1|L|3|M|5|6|7|1X|8|@$9|1Y|A|1Z|B|C]]|D|@]|E|$]]|$1|N|3|O|5|6|7|20|8|@$9|21|A|22|B|P]]|D|@]|E|$]]|$1|Q|3|R|5|6|7|23|8|@]|D|@]|E|$]]|$1|S|3|T|5|6|7|24|8|@$9|25|A|26|B|P]]|D|@]|E|$]]|$1|U|3|V|5|6|7|27|8|@$9|28|A|29|B|C]]|D|@]|E|$]]|$1|W|3|X|5|6|7|2A|8|@]|D|@]|E|$]]|$1|Y|3|-4|5|6|7|2B|8|@]|D|@]|E|$]]|$1|Z|3|10|5|11|7|2C|8|@$9|2D|A|2E|B|C]]|D|@]|E|$]]|$1|12|3|13|5|11|7|2F|8|@]|D|@]|E|$]]|$1|14|3|15|5|11|7|2G|8|@$9|2H|A|2I|B|C]]|D|@]|E|$]]|$1|16|3|-4|5|6|7|2J|8|@]|D|@]|E|$]]|$1|17|3|18|5|6|7|2K|8|@$9|2L|A|2M|B|C]|$9|2N|A|2O|B|C]|$9|2P|A|2Q|B|C]]|D|@]|E|$]]|$1|19|3|1A|5|1B|7|2R|8|@]|D|@]|E|$]]|$1|1C|3|-4|5|6|7|2S|8|@]|D|@]|E|$]]|$1|1D|3|1E|5|6|7|2T|8|@]|D|@]|E|$]]|$1|1F|3|-4|5|6|7|2U|8|@]|D|@]|E|$]]]|1G|$]]

I had this same issue, and searched the internet for a solution and none of the suggestions didn’t not open by double clicking the <code>.jar</code> file.

In my case the reason is I have multiple JDK &amp; JRE versions installed on my computer. Since I am a software developer working with several different versions for different clients I need to use multiple JDKs in my PC (Windows 10 Pro). So I do not want to change the system variables (i.e. <code>JAVA_HOME</code>, <code>JRE_HOME</code> or <code>PATH</code>), instead I use command prompt to run java in user process whenever I wanted to use a different version.

When installing JDK it registers the <code>.jar</code> file association with latest version we installed in the PC. If you right click on the .jar icon and select properties, it will show that file opens with “Java(TM) Platform SE Binary”. If we look at the registry key: <code>HKEY_CLASSES_ROOT\jarfile\shell\open\command</code>, it will point to latest JDK version.

It is not a good idea (sometimes annoying) to change the registry key every time I want to run an app build from a different version.

So in my situation it is impossible to just double click the <code>.jar</code> file to execute it. But instead I found a work around solution myself. 

Scenario:

Multiple JDKs (1.7, 1.8, 9.0, 10.0, 11.0, and 12.0)are installed in the PC, so the latest installed was 12.0.

Problem

Want to double click an executable <code>.jar</code> developed using JDK 1.8 and didn’t work

This is my work around solution:

<ol>
<li>Create a shortcut for the <code>.jar</code> file that you want to open. </li>
<li>Right click the shortcut icon and select properties -> Shortcut tab </li>
<li>Change the text in the target (for example <code>"D:\Dev\JavaApp1.8.jar"</code>) 
To 

"<code>C:\Program Files\Java\jdk1.8.0\bin\javaw.exe</code>" <code>-jar</code>
 "<code>D:\Dev\JavaApp1.8.jar</code>" </li>
<li>Then click ok Double click the shortcut.</li>
</ol>

It should now open the app.

I had the same issue: 
if I doubleclick on a jar executable file, and my Java application does not start.

So tried to change manually also registry key, but it didn't help me. Tried to reinstall JDK newer/older without any result. (I have several versions of Java) 

And I've solved it only using jarfix program. Jarfix automatically fixed .jar association problem on Windows system. (check regedit: <code>PC\HKEY_CLASSES_ROOT\jarfile\shell\open\command</code>) 

What says Johann Nepomuk Löfflmann:

<blockquote>
 The root cause for the problem above is, that a program has stolen the
 .jar association. If you have installed the Java Runtime Environment
 the first time, the file type called "jar" is assigned to javaw.exe
 correctly. "jar" is an abbreviation for "java archive" and javaw.exe
 is the correct program to execute a .jar. However, on Windows any
 program can steal a file type at any time even if it is already
 associated with a program. Many zip/unzip programs prefer to do this,
 because a jar is stored in the .zip format. If you doubleclick on a
 .jar, your pack program opens the file, rather than javaw runs the
 program, because your pack program ignores the meta information which
 are also stored in a .jar. In the Oracle bug database there is the
 low-priority report 4912211 "add mechanism to restore hijacked .jar
 and .jnlp file extensions", but it has been closed as "Closed, Will
 Not Fix".
 
 You may also miss the file connection with .jar if you are using a
 free OpenJDK without an installer.
</blockquote>

Notice:
my OS is Windows 10, but logic is the same for 7, 8 and so on.

Running a .jar file in a command line works fine, but i am not able to run any .jar file by double clicking on my Windows 7 (64). It seems nothing happens after the double click.

I tried the <code>ftype</code> hint, no success:

<pre><code>ftype jarfile="C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*
</code></pre>

I reinstalled the JDK 7 64-bit, no success.

Any idea?

How to run .jar file by double click on Windows 7 64-bit?
