I am trying to make a FTB server that me and my friends can play on. So, I downloaded the .jar and it said "Choose what to open with. SO, I assigned java binary to what it is opened with. It then now opens, but then not less then a second later, closes. I tested with other .jar files. Each one of them either didn't open at all, or opened quickly, then closes. WHat could be wrong?
More than likely the jar (which is just a zip of the programs main classes) is running into an error and exiting.
In order to find and resolve that error you need to see the error message!
first locate the jar file in either your terminal or command prompt and run the following command
java -jar <YOUR_JAR_FILE_NAME>.jar
You will see any output sent from the java program to the console so you can diagnose and resolve it!
In your terminal, where your .jar file is located, type and run the following command :
java --enable-preview -jar <JAR FILE NAME>.jar
Most probably the .jar fill will open, or it will show you the error, which you can then resolve.

I am a absolute beginner with Python. What I have done so far is I have installed Python with IDLE, Pycharm, Pygame-zero and Pyinstaller too. I have a (.py) file game I would like to turn into a (.exe) file. So I can release my game for my friends to play.
I have entered this command into CMD window "pyinstaller --onefile -w gamename.py"* (*My game is not really called "gamename". I have called it that in this code above. For this example only.)
When in the file folder of my game and then Pyinstaller converts my file into the (.exe) file. But everytime I try to run this file. It fails with this error message - "Fatal Error Detected, Failed To Execute Script Error".
I have watched all kinds of YouTube videos trying to solve this problem and have tried these following fixes:
Updated Pyinstaller (4.3).
Updated Python (3.9.5).
Changed the path in Enviroment Variables to point to Python39\Scripts and resetting my computer.
Coverted the (.py) file to (.exe) by including the console window. Then after running the program after when the console window disappears. Opening the CMD window again and typing the file directly "gamename.exe" to run.
Installing auto-py-to-exe program.
Each time deleting the Main, Dis and Spec files and moving the (.exe) file into the main file folder. With the resources for the games. Music, Images and Sounds.
Testing out my Python script to check. If it doesn't have any errors while loading through IDLE and it doesn't. It works straight away, I can play my game through IDLE. There is no errors in the code of my game script.
And after trying all of these solutions it still hasn't solved this issue.I still have the same error message appearing when trying to run my game. Now I have found out what the meaning is to this error message that appears. Which is:
"Fatal Error: failed to execute
This means something has gone wrong as it's giving you a visual warning about it; this is not an error, it's a warning; the real error has been printed to stdout/stderr. If you open the executable using the terminal or something else that will preserve the console output, you will most likely see a Python error telling you what went wrong. Fixing this and repackaging is the solution to this issue".
I have remade the (.exe) file including the console window and it does explan what the error is. When I try to run my game, the error comes up as:
"FileNotFoundError: {Errno 2} No such file or directory: C:*****\Local\Temp_MEI58602\pgzero\data\icon.png {4268} Failed to execute script.
Any suggestions? On how to fix this error please. So I can run and play my game outside of Python on any PC.
A Possible Answer:
I have found a webpage that has the possible answer to my problem. But I don't know what they mean, because I am a beginner with Python. Can anybody read this and break it down for me? Here is what it say's:
"Pyinstaller packaging exe, missing icons and other issues
Reason
When the exe runs, it will decompress a resource folder named "_MEI*" to a temporary directory on the computer, and delete it when the program ends.
uses a path like ‘\icon.png’ in the program. When the exe is running, it will only search for its own directory, of course it cannot be found.
Two, the solution
Make sure the picture is in this temporary resource folder
This can be done by editing the'.spec' configuration file to add pictures.
(Note: .spec is the file generated by Pyinstaller last time, in your python project directory.)
These are the three pictures I used, which is actually adding three tuples to the "binaries" list
Before the comma is the address of the picture in the python project, after the comma is the address of the package into the ‘_MEI*’ temporary folder.
I have built an ‘img’ folder to store pictures in it. Just put a dot in the root directory, such as (’./img/info.png’,’.’)
Finally, run when packagingpyinstaller program entry.spec, You can add the picture resource.
(Note: Other external resources can also be added in this way, such as .ini, .txt, .exe, etc.)
Make sure the program can find this path
Because the name of the temporary directory is different each time, a method is needed to dynamically obtain this path.
The code is presented, and the core statement is ‘os.path.realpath(sys.path[0])’.
Python running effect is as follows:
Package it as an exe, drag it to the cmd window and run it."
Here is the link to the webpage to the article. Because it makes use of screenshots that I can't include on this webpage;
(https://www.programmersought.com/article/94965073850/)
Please read this acticle and break it down for me. It does seem to be explaining the solution to my problem. But what does it all mean? What pictures is he talking about? Please explain.
I am not sure why but PyInstaller doesn't seem to bundle everything needed for Pygame Zero, including that icon.png file. The solution is simple, though. You just need to use pyinstaller --collect-all pgzero --onefile -w <scipt_name>. If your game has sounds, images or anything like that, remember to include those specific folders as well using --add-data <file_or_folder>. Also, make sure your script includes the following lines.
import pgzrun
# GAME CODE HERE
pgzrun.go()
I hope it helps, even though it is a little late.
hope you all safe and well
I made a jar file like this, it's JavaFX jar, I putted the SDK inside the file
image of the files
also in the run, I made these arguments
#echo off
start "" java --module-path "javafx-sdk-15.0.1\lib" --add-modules javafx.controls,javafx.graphics,javafx.fxml -jar ShapeEditor.jar
exit
it works well on my computer, but when I moved it to another computer, cmd just appears and shutdown itself for no reason, I wish if someone could help me with it!.
this is my first ever JavaFX file, so I'm new to the whole concept
--udpdate:
i created the jar file by adding jar file to articats tab in intelJ as in here
, then went to build and built the jar file, added icons in the folder along with the fx SDK, and made a batch file to make run arguments as mentioned above, ran it and no problem, moved it to another windows 10 pc, ran it and a windows appears momentarily then shutdown
So I upgraded Android SDK tools today and now I'm having a problem getting monkeyrunner to run. I did the standard which is (from the command prompt)
D:\Android\SDK\tools\bin\monkeyrunner.bat D:\ScriptName.py
Note 1: The directory of monkeyrunner.bat changed in this release, so I had to update my command line accordingly.
That fails with the message:
SWT Folder '..\framework\x86_64' does not exist.
I can fix that by editing monkeyrunner.bat and instead of having frameworkdir be set to 'lib' it gets set to '..\lib', the actual location of the monkey runner jar file.
However, when I implement this fix it then gives the error:
Cannot run program "..\framework\adb.exe" cannot find the file specified.
I'm kind of stuck here because no matter what I change in monkeyrunner.bat I get the same message, which indicates to me that the jar file has this directory hardcoded in it or something. It should probably be "....\platform-tools\adb.exe"
Any help would be appreciated.
-open monkeyrunner.bat in notepad
change set frameworkdir=. to set frameworkdir=..\lib everywhere
find the line call "%java_exe%" -Xmx512m "-Djava.ext.dirs=%frameworkdir%;%swt_path%" -Dcom.android.monkeyrunner.bindir= -jar %jarpath% %*
change the value of Dcom.android.monkeyrunner.bindir to the path of the folder containing adb.exe. Mine was under platform-tools
I am having an issue that notepad.exe is not getting opened. The run command itself is successful according to the log. But Nothing is opening. I have just installed AutoItLibrary with pip and downloaded and installed Autoit on my machine. My path is only to Python and Python Scripts directory. I have no other components running. Do I have to have any other thing done? have the code Library|AutoitLibrary |Run|notepad.exe |Send|'abc' Send fails saying no such keyword found. I do not see the notepad opening at any point. I also tried wait for the window where it just waits until time out and comes out without the notepad getting opened.
Got it figured out. A Pip install is not doing the full job. I had to download the distro zip file and run the setup install.
I have an install.bat file and a resource folder. so long as these two files are in the same directory, if you run install.bat, it will install a my lwjgl game. so what im trying to do is make a self extracting file that when completed runs the launch.bat file. I have tried using iexpress, and got it working for the most part. i have added in all my files and such so it will extract to some directory and then i can run the install.bat file to get my program to work. thing is though, i want the exe i created with iexpress to launch install.bat when its finished. so, i tried using the option in iexpress that says it will execute a command when finished the "installation" (using quotes because its not the actual installation, just extracting the files to some directory specified by the user). when i get to the step where it says what i would like to execute during and after the "installation". during the installation i left blank. after the installation i chose the install.bat file. when i try to click next though, it tells me i must choose something for the command during the extraction. I don't have anything specific to do during the installation so i just said "echo." (without quotes). after i was done i tried running the installer. before it even prompted me for a folder to extract to, it told me that echo. could not be executed. so i went back into my installation (via a .sed file) and changed the "echo." to "pause". that didn't work either. i then read on another website that in order to run a file the way i would like to, i put the file name in both the during and after installation boxes. i tried doing that and it didn't work either. can anyone please help me?
If I understood your question correctly you will need to specify what the iexpress must do at the post install command option provided so that cmd.exe is used instead of command.com, eg:
cmd.exe /c filethatyouwanttorun.bat
Refer to the question: Create Batch file for iexpress.
You can use the SED file and then modify the self extraction directive. This will run the batch file that you wanted to run and then install the application. (If you have chosen the option to extract and run an installation in iexpress, a temp folder will be used for the extraction I suppose.)
I'm not sure I understand your question exactly but perhaps a few points would help:
If you want a "do nothing" command, you can use something like:
cmd /c echo.
There is no "command during the extraction". There's only an install program and a post install command. Both of these execute after extraction. If you only need to execute one batch file, put it in the install program line and leave the post install command blank.
You can't ask the user for an extraction path and execute a file. You can only do one or the other. (The install program could prompt the user and copy the files there, though.)
