How can I convert my java program to an .exe file ?
I'd like to create a Windows .exe for a Java program. Previously, I've used JEXECreator for this, but it's not entirely satisfactory because:
The executable sometimes works on the machine on which it was created but not on others.
The program is commercial; if you use the trial version, it adds a nag screen to your application.
I don't need the generated .exe to work if Java is not installed on the target machine (in fact, I think this is impossible).
Any recommendations?

Launch4j perhaps? Can't say I've used it myself, but it sounds like what you're after.

Most of the programs that convert java applications to .exe files are just wrappers around the program, and the end user will still need the JRE installed to run it. As far as I know there aren't any converters that will make it a native executable from bytecode (There have been attempts, but if any turned out successful you would hear of them by now).
As for wrappers, the best ones i've used (as previously suggested) are:
JSmooth
and
Launch4j
best of luck!

If you really want an exe Excelsior JET is a professional level product that compiles to native code:

You can also look at JSMooth:
http://jsmooth.sourceforge.net/
And if your application is compatible with its compatible with AWT/Apache classpath then GCJ compiles to native exe.

I used exe4j to package all java jars into one final .exe file, which user can use it as normal windows application.

You could try exe4j. This is effectively what we use through its cousin install4j.

The Java Service Wrapper might help you, depending on your requirements.

If Java is installed on the target machine, there is no need to create an .exe file. A .jar file should be sufficient.

Create .exe file under Ubuntu in with JavaFX

I created JavaFX application under Ubuntu and I need to create exe file.
Is it possible to do that under Linux?
I guess by "exe" file you are referring to a "standalone binary" that doesn't require its users to have a JRE installed on their system.
Short answer: no, that isn't really an option in practical reality.
What you can do instead: deploy your whole application into a single JAR and use a script wrapper around it. That makes it easier for folks to invoke your JAR.
For the "long" answer on creating binaries; see here.

Easy way to make a runnable program out of a java project

Im doing a small Java project with some school kids to teach them programming and at the end of this project hopefully we will have a small Game.
I would like to give these kids some sort of "exe" file(on an USB-Stick) that should run if you double click it.
I can produce a .jar file, but that wont execute on double clicking it.
The first thing i can think of is a .bat file with java -jar [game.jar] as content but this would require an installed JRE.
Is there any better(but not too complex) way to generate a file(or directory with file in it) that could run anywhere(on Windows is enough) like a portable JRE?
The best solution would be a single File like a self-extracting zip.
You can use Launch4j, it makes an .exe which tries to run the program and if no JRE is found it leads them to the download page of the JRE. I'm just not sure if it can make an .exe with embedded JRE.
Their website: http://launch4j.sourceforge.net/
Because you are using Java, which is dependent on the JRE to run, you are not going to get around not having the JRE installed without significant legwork. Just package instructions with the flash drives you give the kids!
If you're committed though, look into http://www.excelsiorjet.com/ or http://www.duckware.com/jexepack/index.html.
As well as this SO question: How can I convert my Java program to an .exe file?
I can produce a .jar file, but that wont execute on double clicking it.
Why doesn't this work? Is it an issue with having a JRE present, and that these kids might not have it, or might not be able to install it on other's machines?
I suggest you go here if you want go the "exe" route.
http://www.excelsiorjet.com/free
if you click "free licenses" you can get apply for a free license of I believe the "standard edition."
This should be "Good enough" for your intended purposes, and you wont need a JRE present.
It's more work on your end, but it should work nicely for your needs.

How to make an executable JAR file?

I wrote a JAVA program for my wife to compare coupons stacked with sales on different item sizes to save her time on her shopping-trip-planning. Now I need to put it on her computer in such a way that she can double-click something, and have the program run. I'm not finding anything good on the interwebs (like a decent step by step).
It is a simple program, one class with a nested class, and various imports of swing, awt, and text.
Since it's my wife's computer, I can make sure that she is running the appropriate JRE. Thanks in advance for any help.
You can use Launch4j application. That convert executable jar file to windows native executable application.
You can also embed JRE with it so if JRE is not installed on machine the application will run.
you can also add some other mechanism to it also like loading image, icon, etc.
I assume you are using Eclipse. In this website they given it very clearly for eclipse.
Create Executable files in eclipse
Export it to (or create a) executable Jar.
Most IDE's will do this (I think you have to dig around Eclipse a little) or take a look at Packaging Programs in JAR Files and Setting an Application's Entry Point if you want to do it by hand
Most GUI OS's will run the Jar via a double click.
You could also investigate generating a native executable wrapper, which will make the program "look" more familiar to the user, including launch4j or exe4j or Packaging a Java App for Distribution on a Mac depending on your target platform
Use NetBeans and simply 'Build' the jar file. This will produce an executable file within the 'dist' folder of your project.
Eclipse is the same however slightly more hidden.

Have a Java application (JAR) that needs to be executable. (Built In Eclipse)

I have this little application (JAR) built in Java on Eclipse and it needs to be compiled into an executable file that people can just double-click and it runs. Ideally this would an exe filetype. I'm not so versed with java and what the needs are but I'm hoping it can be compiled to run one computers that maybe don't have java installed.
Is there any advice or direction you can point me to so I can figure this out?
Many thanks.
Ideally this would an exe filetype.
No, ideally this would be a Jar file. Just leave it be a jar file. It will work fine if you set up your platform to respond to double clicks correctly. And yes the computer will need to have Java installed -- that's not an onerous requirement.
Try this application : exe4j : http://www.ej-technologies.com/products/exe4j/overview.html
It runs on various platforms to made EXE files :))
You won't be able to make it run on PCs without Java installed.
There are plenty of guides on how to make an executable jar to run on computers with Java installed: take your pick: java executable jar creation, Make JAR as a standalone executable and so on...

How to generate an exe file from my java project ? Which tool should I use?

I was asked to make a program (in java) by some person but I was stacked as I didn't know how to generate and exe file from my jar file... It would be useless If I install for them the jdk environment as this person don't how to program... Does anyone knows ho to do this or what tool should I use ?
Regards from Córdoba Capital, Argentina...Thanks in advance !!!
You could use launch4J, it's pretty simple to use and to configure.
Read this post, it may help

Here is a post from earlier that has some other options:
How to create a Java application which can be run by a click?
As Lucas mentions above, you will need to install the JRE on the user's machine to get a Java app to run properly. If it is a small program, you could consider making a .bat file (or .sh file on *nux) to allow the user to run the program. Your bat file could as simple as the one below. Just put in a .bat file and add as a short cut. I know there are more elegant solutions out there, but this is simple and should work.
setlocal
set CP=<PATH TO ANY DEPENDENT LIBRARIES OR JARS>
start javaw -cp %CP% <FULLY QUALIFIED MAIN METHOD> <PROGRAM PROPERTIES>
endlocal
They don't need to install the entire JDK to run the jar file, all they need is the significantly smaller JRE. This is standard practice when distributing java applications.
A big advantage of running your java program on the jvm as compared to generating a native binary is that it will, assuming you aren't using a platform-dependent library, be platform-independent straight away.
You can use Excelsior JET. It is not free, work quite slow, but you can create executable (very huge executable). I tested it on Windows and it worked. But executable it created was slower then .jar run using JRE.
There is also GCJ. I tried it, but it was too hard for me to compile my project.
I suggest installing JRE and working with .jar file.
