How can I run Java applet from web on local (Windows 7)?
I downloaded file A.jar.pack.gz from web. This file I unpacked by unpack200.exe and after running unpacking jar there is this: Error: Invalid or corrupt jarfile C:\...
If you have installed the jdk then
You can extract the jar file through the following command :
step 1: jar xvf jarfilename
and then
step 2: create any text or html file and make the following entry:
<applet code="className" archive="jarname" height="any number" width="anynumber">
</applet>
the classname can be found when you have extracted the jar through the step 1
step 3: appletviewer filename
and yes ofcourse for the above commands to work you must set the path till jdk\bin
If a java program is written to be an applet, it will assume that it has all the support structure of an external applet player, browser, etc. It therefore generally won't be able to run on its own as a Java program.
Vijay's solution could work, as might opening your new HTML snippet in a browser. The only way to get it to run with nothing but Java would be to rewrite bits of the program to provide a stand alone interface, or contact the original developers asking whether they'd be willing to do so.

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;

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
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 currently working with a Java based jetty server setup which involves servlet and HTML. The objective is to call R script from Java
In one of the custom configuration properties file inside WEB-INF/classes, I have encountered a statement as follows.
RScriptLocation=/usr/local/bin/Rnobody
This property file is not related to jetty server, it is the developer who created this properties file for storing constants.
I have installed R from cygwin setup, but I could not locate that particular executable, I only see /usr/bin/R
what is Rnobody and how to install it
I'm using a Windows 7 x64 machine with R-3.1.0. I installed the Rserve package through Rstudio.
The start of Rserve is successful with the following code in Rstudio:
library(Rserve)
Rserve()
I got the following output:
Starting Rserve...
"C:\R\R-31~1.0\library\Rserve\libs\x64\Rserve.exe"
My problem is that I couldn't locate the configuration file. Apparently it can't be "/etc/Rserv.conf".
I did come across a webpage saying that the config file is Rserv.cfg in the working directory (unless changed at compile-time). But which working directory? I have checked the working directory of the current R project as well as the Rserve library directory, but it was not there...Could someone help me with this please? Thank you.
Rserve does not automatically come with a config file, you must make one. Best steps for doing so:
Navigate to the file where you just installed Rserve.exe (C:\R\R-31~1.0\library\Rserve\libs\x64\R, based on the message you copied here)
Find Rserve.exe, Reserve_d.exe, and Rserve.dll there. Copy these files.
Navigate to where R.dll is on your computer. This is probably C:\Program Files\R\R-3.1.3\bin\x64, but may be different depending on where you installed R to.
Copy the 3 files mentioned above to this location.
Create a text file here named "Rserv.cfg" with the arguments you are looking for, such as port 6312 or library(mvoutlier). Yes, I know that this is different from the documentation, but if you start Rserve_d.exe you will see that this is the file it is looking for. I have not had success naming it anything else.
You can start Rserve by specifying the location of the config file. In R instead of just Rserve() try the following:
Rserve(args="--RS-conf C:\\folder\\Rserv.cfg")
If path is more complicated you need to massage it a little bit:
Rserve(args="--RS-conf C:\\PROGRA~1\\R\\R-215~1.2\\library\\Rserve\\Rserv.cfg")
Look in the $RHOME/bin directory
If you can't find it here is a different way to approach it:
Download Rserve at [http://rforge.net/snapshot/Rserve_.tar.gz], and save it in your desired directory
Run R CMD INSTALL Rserve_.tar.gz
This allows you to leave Rserve where you want it.
After looking at the Rserve source code and making some test I found that on Windows platform Rserve try to load the configuration file from the current working directory. Also pay attention because on Windows the file name is RServ.cfg and not Rserv.conf as documented.
The current working directory depends of the process, for example using RStudio by default it is your Documents and Settings folder:
C:\Users\[username]\Documents
but can be changed in the "Global Options" of the IDE
So you can create an "RServ.cfg" text file in that directory with your needed options and starting RServe in the usual way in RStudio
Rserve()
will load your configuration.
