You may have several JDKs installed in your PC. Some older JDK installers also copy some java files such as <code>java.exe</code>, <code>javaw.exe</code> into <code>C:\Windows\System32</code> folder.
I had a similar issue, and searched the internet for a solution and none of the suggestions didn’t 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 -&gt; Shortcut tab
</li>
<li>Change the text in the target (for example <code>&quot;D:\Dev\JavaApp1.8.jar&quot;</code>)
To
&quot;<code>C:\Program Files\Java\jdk1.8.0\bin\javaw.exe</code>&quot; <code>-jar</code>
&quot;<code>D:\Dev\JavaApp1.8.jar</code>&quot;
</li>
<li>Then click ok Double click the shortcut.
</li>
</ol>
It should now open the app.

I was having this same issue for both Windows 8 and Windows Server 2012 configurations.
I had installed the latest version of JDK Java 7 and had set my <code>**JAVA_HOME**</code>system env variable to the jre folder: <code>*C:\Program Files (x86)\Java\jre7*
</code>
I also added the bin folder to my <code>**Path**</code> system env variable: <code>*%JAVA_HOME%\bin</code>*

But I was still having problems with double clicking the executable jar files. I found another system env variable <code>OPENDS_JAVA_ARGS</code> that can be used to set the optional properties for javaw.exe. So I added this variable and set it to: <code>-jar</code>

Now I am able to run the executable jar files when double clicking them.

In cmd you can use the following:

However, you need to create you .jar file on your project if you use Netbeans. How just go to Run ->Clean and Build Project(your project name)

Also make sure you project properties Build->Packing has a yourFile.jar
and check Build JAR after Compiling
 check Copy Depentent Libraries

Warning: Make sure your Environmental variables for Java are properly set.

Old way to compile and run a Java File from the command prompt (cmd)

Copy this code to a .txt file, modify "YourName" and save as "myjar.bat". Then whenever you double click, the jar file will be executed.

first of all, we have to make sure that you have downloaded and installed the JDK.
In order to download it click on the following link

<a href="http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html" rel="nofollow">http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html</a>

(Do not forget to check "Accept License Agreement", before you choose the version you want to download)

For Windows OS 32-Bit (x86) choose "jdk-8u77-windows-i586.exe"

For Windows OS 64-Bit (x64) choose "jdk-8u77-windows-x64.exe"

Install the file that is going to be downloaded. During the installation, pay attention, because you have to keep the installation path.

When you have done so, the last thing to do, is to define two "Environment Variables".

The first "Environmental Variable" name should be:

<code>JAVA_HOME</code> 
and its value should be the installation path

(for example: <code>C:\Program Files\Java\jdk1.8.0_77</code>)

The second "Environmental Variable" name should be:

<code>JRE_HOME</code> and its value should be the installation path

(for example <code>C:\Program Files\Java\jre8</code>)

As soon as you have defined the Environment Variables, you can go to command prompt (cdm) and run from every path your preferred "java.exe" commands. Your command line can now recognize your "java.exe" commands. 

:)

P.S.: In order to define "Environment Variable", make a right click on "This PC" and select "properties" from the menu. Then the "System" window will appear and you have to click on "Advanced system settings". As a consequence "System properties" window shows. Select the "Advanced" tab and click on "Environment Variables" button. You can now define the aforementioned variables and you're done

I had this problem a while back and the solution was really easy.

Just uninstall the current version of <code>Java</code>, download an older one, then uninstall the older and install the latest again.

For example: <code>Java 8 Update 73</code> current install Java 7 Update 95.

How it works: <code>Java</code>'s registry keys were messed up, and when you install the older version they get fixed.

If the intention of the question is to view the contents of the JAR file, then the following java command would help.. (provided, JDK location is added to the environment variables.)
Windows Command prompt&gt; jar tvf yourJarFile.jar
<ul>
<li>Example:
jar tvf log4j-extras-1.2.17.jar
</li>
</ul>

I downloaded the latest JDK 7u10. Once you do that, try running your jar, It should execute.

I can't open or run my .jar file.

I just installed java, but I tried to open the .jar with other programs first, so the double-click defaults to something else and I can't change it back.

<pre><code>java -jar myfile.jar`
</code></pre>

Above command returns:

<blockquote>
 'java' is not recognized as an internal or external command, operable program or batch file.
</blockquote>

Is there a way I can still open/run this?

e: OS is Windows 8.

Also, I downloaded the .jar file; didn't create it myself (if that's relevant)
Not sure if it contains an executable (but I think it does).
