I've created Java runtime image for a simple OpenJFX application. In order to run this app, jlink auto-generated two lauch scripts under %image_path%/bin directory. This how it looks like (the one for Windows):
#echo off
set JLINK_VM_OPTIONS=
set DIR=%~dp0
"%DIR%\java" %JLINK_VM_OPTIONS% -m app/com.package.Launcher %*
Obviously, when I run this batch file it opens new shell window, which is not what I want to. I've tried all common approaches: use javaw instead of java, run script via start command etc. Nothing works.
Is it possible to avoid shell window or somehow create native launcher?
Ok, I've figured out it's not posiible to eliminite shell window completely. In the best scenario it's just flickers for ~1sec. This is how it can be achieved:
#echo off
set JLINK_VM_OPTIONS=
set DIR=%~dp0
start "" "%DIR%\javaw" %JLINK_VM_OPTIONS% -m app/com.package.Launcher %* && exit 0
There is a feature request about native laucher implementation but it's not discussed actively.
Nonetheless I've solved the problem. There is "Batch to EXE Converter" tool. It can generate executable (basically the same batch file) which can run your app silently.
This looks to be possible using vbscript. If you put the following script into a .vbs file next to the launcher.bat file (or whatever the name of the batch file is):
CreateObject("Wscript.Shell").Run CreateObject("Scripting.FileSystemObject").GetParentFolderName(WScript.ScriptFullName) & "\launcher.bat " & WScript.Arguments(0) & " > " & CreateObject("Scripting.FileSystemObject").GetParentFolderName(WScript.ScriptFullName) & "\launch-log.log", 0, False
This runs the batch file in the same directory, and also redirects stdout to a log file.
What you´d like to achieve is very well possible. It is actually even quite easy and I use this every day. There already is an early access build of jpackage available here: http://jdk.java.net/jpackage/ Creating executables works already
nicely (I use it on Mac and Windows). Only creating installers is still a bit problematic.
It's very easy to run a bat file without showing the cmd window.
you just need to create VBS file to run bat file with the following cmd
Set WshShell = CreateObject("WScript.Shell")
WshShell.Run chr(34) & ".\bin\launcher.bat" & Chr(34), 0
Set WshShell = Nothing
Save cmd in the file out of the bin folder with any name like
Launcher.vbs.

Everybody probably has used install .exe files. But how to make them and when does it make sense to make one?
For example, I would have had programmed commercial software in Python, c++, etc. with different files a GUI and pictures and all of the other stuff.
When I want to deliver my product to my customer I don't want to give them a folder and say you need to install Python or Java and execute the program via your command line.
How can I create an executable file that installs the required language and sets up local instances and arranges all files into the correct order?
To create an executable file from a python program, there is pyinstaller. I don't know about java at the moment. The command is as follows :
pyinstaller fileName.py
You can add args (and there are 2 really helpful ones) :
pyinstaller --onefile -w fileName.py
--onefile will put everything into one single file (recommended) and -w will prevent the console from opening when running the .exe file. Add it if you're running a GUI or something. If you need to console for input, don't add -w.
If you want to automate a command line in cmd, create a shortcut leading to C:\Windows\system32\cmd.exe and add /k and your command. For example :
C:\Windows\system32\cmd.exe /k ipconfig
Double clicking on the shortcut will now run the cmd and execute ipconfig automatically. If you want more than one command, you can do command_1 && command_2 && ... && command_n
There is a setup program built into Windows.
Type
iexpress
and follow the wizard.
You need to provide code to run when it finishes to actually install the extracted files.;
I'm using Apple's automator to create a Shell Script. I can get it to run if I change directory specifically to where the jar file is. But what if I want to change to directory to wherever the Shell script happens to be running?
Right now I have the following, which works:
cd desktop/CommonDenom/
java -XstartOnFirstThread -jar CommonDenom.jar
I know there's a way to target whatever directory the Shell script is launched from, but I can't seem to get anything to work. Please be specific with instructions as I havent been using Automator very long. Unless someone can specify how ot writ ethe script without Automator. Thanks in advance.
A standard idiom for this in shell scripts is dirname $0. The $0 variable is the path to the script that was executed, and the dirname command takes a path and strips off the last component to leave the path to the containing directory
cd "`dirname $0`"
Just wanted to weigh in here. I've seen some people with this problem. If you are JUST on OSX and making your own scripts. This will do the trick :) kind of a hack, but works like a charm.
#! /bin/bash
sudo /Applications/XAMPP/xamppfiles/xampp startapache
open /Applications/XAMPP/htdocs
#!/bin/bash
DIR=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )
cd "${DIR}"
...the rest of your script...

I am not sure you mean "you want to change directory to wherever the script is run from" because you will be in the directory the script is run from when you start anyway, so there will be no need to change directory there. I think you mean you want the script to stay wherever it starts, yet still be able to find the jar file.
In which case, you probably jus need the following without any changing directory:
java -XstartOnFirstThread -jar ~/Desktop/CommonDemon/CommonDemon.jar
I'm building a server in Java. I want to setup a single word option that will start and stop the server. "start" to start the server. "stop" to stop the server. I tried to use an executable file that launched the jar, but even using that strategy, I still have to type "./start". The punctuation is a little ugly.
I wanted something similar to "git". If you type "git" in Terminal, you are immediately using git's tools. I'm guessing this is because of a symlink? If so, how did the symlink for "git" get setup? I didn't have to manually set it up from what I remember.
If you would like to avoid sh or ./ while executing you may use alias, add following at the end in ~/.bashrc file:
alias sayhello="./sayhello.sh"
And then run the .bashrc file using following command:
source .bashrc
Finally, you should be able to execute your command using just:
sayhello
What OS are you working on? In windows you just have to add the location of start.exe to your PATH, then typing "start" in the command prompt will launch the executable and the jar
I'm using Sublime Text 2, and I want to be able to compile and run Java Files with one button.
When running Windows, the Batch file Required is:
#ECHO OFF
cd %~dp1
javac %~nx1
java %~n1
I'm wondering what that would look like in a Shell Script, cause I don't know much about Shell Scripts...
I'm using the Open JDK and JRE in case it matters.
Thanks for the help,
Kelan
The bash equivalent to that script would be something like:
#!/bin/bash
cd "$(dirname "$1")"
javac "$(basename "$1")"
java "$(basename "$1" ".${1##*.}")"
A shell script would STILL require running a batch file to start it. For example, you could write a Ant task that could do what you are asking, or perhaps a Beanshell script. But, you still wont be able to avoid making a batch file that launches it. The batch file that you are using now is as close as you'll get to a single click solution. Not even a PowerShell script would give you better convenience.
You launch a java program from a console (maybe using a .bat script).
I don't want the console to remain visible, I want to hide it.
Is there a simple way to do this ? Without JNI ?
Use javaw.
http://java.sun.com/javase/6/docs/tooldocs/windows/java.html
The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you don't want a command prompt window to appear. The javaw launcher will, however, display a dialog box with error information if a launch fails for some reason.
You can start a java application with start javaw. It will hide the black console window.
This .bat trick works for general programs so I think it should also work for launching java program:
Call start program instead of just program in your .bat script
You can hide the console by using javaw.exe (java without) instead of using java.exe.
One of the most useful associations to set up is to make *.jar files executable with java.exe. Then you can just type the name of the jar on the command line to start it executing.
If you use javaw.exe rather than java.exe you won’t see the console output. Watch out, Java installers often associate *.jar files with javaw.exe instead of java.exe, overriding your setting.
download jsmooth and create your own custom exe in a minute or two. Then just use that exe to launch your java app. You can even get slick and bundle a JRE with your app.
http://jsmooth.sourceforge.net
In case fo running from but file your script should look like
start javaw start javaw -jar ***.jar
Note, that you may need running javaw.exe by providing full path to the file, that may need adding quotes " in case there are spaces in the path. The quotes will trigger recognition of them as "title"-argument for the "start" command.
So, use following correct format:
start "MyTitle" "c:\Program Files (x86)\Java\jdk1.8.0_202\bin\javaw.exe" -jar myApp.jar
where title can be empty if needed
