i have created a java project in NetBeans. now i want to make an executable file out of it.that can be executed (run) in other computers that have JDK or JRE installed but don't have NetBeans or any other Java IDE installed.how can i do such thing using NetBeans???

Do you mean compile it to JAR? Netbeans does that automatically, just do clean and build (hammer sybol) and look in the dist subdirectory of your project. There will be the JAR with lib folder containing the required libraries. These JAR + lib are enough to run the application.
Maby you unchecked an option:
Project Properties -> Build -> Packaging -> Build JAR after compiling
(but this is enabled by default)

You have to build your project. Just click on the hammer in the toolbar.
After that there should be a folder in your project called "dist".
In it is the *.jar File, which you can deploy to anybody who has Java installed.

you mean executable jar file. which can be executed using $java -jar myJar.jar . So you need to change manifest file inside jar. Second if you want a mouse double click execution then for Linux create .sh and for windows create .bat file containing the above specified $java -jar .
JVM installation is required to do so on whichever machine you want to execute.

some Jar files open with double click, others do not

Have 4 different Java projects, completely independent, and all build a Jar. All created in IntelliJ (2022.2.2 Ultimate) on MacOS (Monterey 12.6), built to target Java 8.
2 of the Jars open as expected by a double click, and 2 do not (error message to check for problems in log files via Console but could never find any).
The Jars all created within IntelliJ as an artifact of the project, and AFAIK the same process and options.
One of the Jars will also not open on the command line with either:
java -jar MyJarFile.jar (the Jar does contain the correct manifest)
java -cp MyJarFile.jar package.mainclass
but if you do:
unzip MyJarFile.jar
to unzip the jar into the current directory then:
java package.mainclass
starts the application as expected.
No change to the external environment (JAVA_HOME, etc) between any of the projects.
Something has to be different .... but what?
Any suggestions appreciated.

Can I bundle all java classes in to jar app?

I have created a project to collect the daily status in an xls sheet, using the selenium webdriver.
Currently it runs well.
Can I make this project into a standalone application or a executable jar? Or is there some other way to collect the status by clicking on the application or jar to open it without having to compile and run from eclipse?
You can use install4j from below mention URL. It will make executable jar and application.exe also you can make installer for different platforms such as Mac, Windows and Linux.

hope it will help
From Eclipse select Export -> Runnable JAR File
Select 'Extract required libraries into generated JAR'
When you have your JAR file execute :
java -jar MyJar.jar

I made my first application with Java in Eclipse now I need to repackage or create an executable file file from that project. I used a lot of external jar libraries that I would like to export whit the project. Any solution is welcome.
I suggest to use apache maven to make a fat jar in conjunction with the launch4j maven plugin to make an self-contained exe (i.e. a wrapper for the jar).
you can make a executable jar file of that project. And then make a .bat file. From that .bat file you can invoke that executable jar.
Eclipse will pack you yourprojectname.jar file, which is executable file. So, in order to run it you may just run in command line (a.k.a cmd) java -jar path/to/your/project.jar. And of course it is more easier to run it with script. There are .bat files which are something like .bash scripts in linux/unix
Right click on your Eclipse project in ProjectExplorer
Export...
Java\Runnable jar file
On dialog Runnable JAR file export
4.1. Choose the main() method you need to start from the popup "Launch configuration"
4.2. Specify the output jar like: d:\dest.jar
4.3. "Finish'

How to add jdk in a.jar file and run it

I have made a runnable .jar file. I want to run it on a PC which does not have jdk instilled, Can I add jdk in .jar file itself and run it ?
Suppose that your have installed your Java in the following path:
1 - copy this jre folder
C:\Program Files\Java\jdk1.7.0_25\jre
now all you need is to create a .bat text file with the following content:
#echo off
jre\bin\java -jar your_filename.jar
2 - name it as run.bat
that's all you need.
To wrap up things, the directory structure should be:
|---jre
|---bin
|---... // other files and folders
|---run.bat
|---your_filename.jar
click or create shortcut from run.bat and that's it.
If you are more interested in having a stand-alone executable file, then take a look at Launch4j (google it :) )
You don't need the JDK for it to run, just the JRE (Java Runtime Environment). You can download the JRE from here.
This is, unfortunately for you, something that will be needed to execute your code.

How do I run a .jar executable java file from outside NetBeans IDE?

How do I run a .jar executable java file from outside NetBeans IDE? (Windows Vista). My project has a .jar file created by Netbeans. We'd like to run it. Either: how do we run the file or how do we create a 'proper' executable file in NetBeans 6.1?
Running a jar is as simple as
java -jar filename.jar
as Laplie said, java -jar your.jar
EXECUTABLE file : see this thread for answers How can I convert my Java program to an .exe file?
One of the best technique to run the jar file or jar jar file
Create the jar file by jar command choose your jar filename
Java_Jar_File.jar
Run the jar file us the command like java -jar Java_Jar_File.jar
You can do it from the command prompt if java isn't in your path by finding the full path to your java install, something like:
C:\java\java.exe -jar C:\jar_you_want_to_run.jar
or if java is in your path:
java.exe -jar jar_you_want_to_run.jar
This will run the jar produced by netbeans.
First, make sure you set the Main Class in your NetBeans project properties dialog.
Then, you can either
Double-click the jar file (This should work on any machine with an installed JRE)
or
Make sure that java.exe is in the path (or replace java below with the fullpath and file name of the executable), put the following in a batch file:
java -jar filename.jar
Then you can double-click the batch file instead of the jar (useful if you have people unaccustomed to using naked jar files)
OR
You can go down the path described here How can I convert my Java program to an .exe file? to build a .exe for windows.
Make a BAT file with
java -jar filepath.jar
from a command prompt you can run this command: java -jar your_jar.jar.
To run a java jar file its file association should be properly configured. There is a free tool called jarfix to fix all jar file association problems. Run this file to fix all jar issues.
In the project properties dialog in NetBeans you need to set the Main Class - otherwise the generated .jar will not be executable. Then, as already indicated, either double clicking on the .jar or the command java -jar will start the program.
If you have problems with running your jar, make sure you are trying to run your current version to get newest version in Netbeans: GoTo Run Menu --> Clean and build
