Run Keygen.Jar
How can the answer be improved? How to run a jar file created using intellij 12. Im terminal, go to dir where jars have been produced and to run do: java -jar yourjarfile.jar.
I have a JAR file named helloworld.jar.In order to run it, I'm executing the following command in a command-line window:
This works fine, but how do I execute it with double-click instead?Do I need to install any software?

Easiest route is probably upgrading or re-installing the Java Runtime Environment (JRE).
Or this:
- 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 FilesJavaj2re1.4.2_04binjavaw.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.

In Windows Vista or Windows 7, the manual file association editor has been removed.
The easiest way is to run Jarfix, a tiny but powerful freeware tool. Just run it and your Java apps is back.. double-clickable again.
If you need to distribute your .jar file and make it runnable at other people's Windows computers,you can make a simple .bat file like this in the command prompt:
and place the .bat file in the same directory as your .jar file.
If you have a jar file called Example.jar, follow these rules:
- Open a
notepad.exe
- Write :
java -jar Example.jar
- Save it with the extension
.bat
- Copy it to the directory which has the
.jar
file - Double click it to run your
.jar
file
An interesting side effect of this causes a problem when starting runnable jar files in the command prompt.
If you try (in a command prompt):
No joy, because this is being translated to the following (which doesn't work):
However, the following command does work:
If you change the association in file manager as described above to:
Then you can type:
in the command prompt and it will now work!
EDIT:(However you then get a black console window when you run a form based (non console) Java app, so this is not an ideal solution)
If you run these jar files by double clicking them in windows, no parameters will be passed so your Java code needs to handle the stack overflow exception and include a 'press a key' function at the end or the window will just disappear. Intel hd graphics.
In order to pass a parameter in windows you have to create a shortcut to the jar file, which includes the parameter in the target line (right click on the shortcut and select properties) you can not add parameters to the jar file icon itself in this way.
There isn't a single, consistent solution here, but you would have the same problem with any other console application.
There is a windows freeware application called 'bat to exe' which you can use to create an exe file from a .bat file with the apropriate command line in it. you can also embed the jar file in the exe with this application, and make it clean it up when it has finished running, so this may be a more elegant solution.
In Windows XP * you need just 2 shell commands:
obviously using the correct path for the JRE and any name you want instead of myjarfile
.
To just check the current settings:
this time using the value returned by the first command, if any, instead of jarfile
.
*not tested with Windows 7
Besides all of the other suggestions, there is one other thing you need to consider. Is your helloworld.jar a console program? If it is, then I don't believe you'll be able to make it into a double-clickable jar file. Console programs use the regular cmd.exe shell window for their input and output. Usually the jar 'launcher' is bound to javaw.exe which doesn't create a command-shell window.
There is way without requiring user to do changes on his PC. Runtime.getRuntime.exec() allows us to start cmd.exe and execute commands inside of it. So, it's possible for java program to run itself in command prompt when user clicks .jar file.
I´m running Windows 7 x64 and was unable to use any of these fixes.
This one worked for me afterall:
There is an archive which you can download containing a .bat file to run, but check the path of the actual javaw.exe!!!!
You want to check a couple of things; if this is your own jar file, make sure you have defined a Main-class in the manifest. Since we know you can run it from the command line, the other thing to do is create a windows shortcut, and modify the properties (you'll have to look around, I don't have a Windows machine to look at) so that the command it executes on open is the java -jar command you mentioned.
The other thing: if something isn't confused, it should work anyway; check and make sure you have java associated with the .jar extension.
In regedit, open HKEY_CLASSES_ROOTApplicationsjava.exeshellopencommand
Double click on default on the left and add -jar between the java.exe
path and the '%1
' argument.
Unfortunatelly, it is not so easy as Microsoft has removed advanced file association dialog in recent Windows editions. - With newer Windows versions you may only specify the application that is going to be used to open .jar file.
Fixing .jar file opening on Windows requires two steps.
Open the Control Panel, and chose 'Default Programs -> Set Associations'. Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as 'Java Platform(SE)'. A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the 'Change..' button.
Now open the regedit, and open the
HKEY_CLASSES_ROOTjarfileshellopencommand
key. Luckilly for us, we may specify parameters there for the(Default)
value. On my Windows system it looks like:C:app32jre7binjavaw.exe' -jar '%1' %*
but in most cases it is the following string:C:Program FilesJavajre7binjavaw.exe' -jar '%1' %*
NOTES:
- Do not use
java.exe
there as it will open the shell window. - The jarfix tool mentioned in this thread most likely does nothing more than the registry modification for you. I prefer manual registry change method, as that implies that system administrator can 'push' the registry change to all workstations in the network.
Run Keygen On Windows
I had the same problem in Windows 10. I fixed it using righ-click on the 'helloworld.jar' and go to properties and click on change button under 'Opens with:' and select 'Look for another app on this PC'. In the 'Open with..' dialog box, go to your Java folder location on your PC and open corresponding jdk folder and then open the bin folder and select 'javaw.exe' from there. Then next time your 'helloworld.jar' will open the normal way.
Usual java location example : 'C:Program Files (x86)Javajdk1.8.0_111bin'.
Another way to run jar files with a click/double-click, is to prepend '-jar ' to thefile's name. For example, you would rename the file MyJar.jar
to -jar MyJar.jar
.
You must have the .class
files associated with java.exe
, of course. This might not work in all cases, but it has worked most times for me.
PreScript: If your prompt appears and disappears immediately, the reason it does so is that your program gets executed and auto shut. Try putting a scanner in the end to terminate and it'll keep your prompt waiting for input before terminating. (Or use delay maybe)
Was in the very same situation, where running .jar from cmd was working fine, but double clicking did nothing.
Solution:Open any text editor and write the command line: java -jar Example.jarSave the file as a .bat file.Run this bat file to get the needed output.
Taking it one step forward, you can convert this bat file to exe file using a simple GUI tool like Bat To Exe Converter.
Now you can share your .jar as a distribution in .exe file which anyone can use just make sure you keep all the files together. (Especially the .jar and .bat file cause .bat is only a cmd prompt)(How it feels logical)
I am fairly new to development and learning a lot. Please excuse for any mistakes if committed. Suggestions are welcome.
If you use eclipse for making your java files, you can choose to export it as a runnable jar file. I did this with my programs and I can just click on the jar and it will run just like that. This will work on both windows, as well as os x.
Making a start.bat was the only thing that worked for me.
open a text document and enter. java -jar whatever yours is called .jar
save as start.bat in the same folder as the .jar file you want to execute. and then run the. bat
If you need to run the jar file by double clicking on it, you have to create it as a 'Runnable JAR'. you can do it simply with your IDE.
If you're using eclipse, follow these steps :

There are many methods for running .jar file on windows. One of them is using the command prompt.
Steps :
- Open command prompt(Run as administrator)
- Now write 'cd' command for root directory
- Type 'java jar filename.jar'Note: you can also use any third party apps like WinRAR, jarfix, etc.
Steps:
1.) search for Java SE Runtime Environment on Google: https://www.google.com/search?q=Java+SE+Runtime+Environment
2.) install the appropriate version onto your computer
Create .bat
file:
And choose app default to open .jar
with this .bat
file.
It will close cmd
when start your .jar
file.

In you jar directory(the location where your jar present), create a file with .bat
extension and content as java -jar yourJarName.jar
and save it.
now you can double click on this bat file to run your jar.
