I've just made a simple program with eclipse and I want to compile it into an executable, but simply can't seem to find out how to do it. Please help.

You can convert .jar file to .exe on these ways:

alt text

1- JSmooth .exe wrapper:

JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a web site.


JSmooth provides a variety of wrappers for your java application, each of them having their own behaviour: Choose your flavour!


Download: http://jsmooth.sourceforge.net/


2- JarToExe 1.8

Jar2Exe is a tool to convert jar files into exe files. Following are the main features as describe in their website:


Can generate “Console”, “Windows GUI”, “Windows Service” three types of exe files.

Generated exe files can add program icons and version information.

Generated exe files can encrypt and protect java programs, no temporary files will be generated when program runs.

Generated exe files provide system tray icon support.

Generated exe files provide record system event log support.

Generated windows service exe files are able to install/uninstall itself, and support service pause/continue.

New release of x64 version, can create 64 bits executives. (May 18, 2008)

Both wizard mode and command line mode supported. (May 18, 2008)

Download: http://www.brothersoft.com/jartoexe-75019.html


3- Executor

Package your Java application as a jar, and Executor will turn the jar into a Windows exe file, indistinguishable from a native application. Simply double-clicking the exe file will invoke the Java Runtime Environment and launch your application.


Download: http://mpowers.net/executor/


EDIT: The above link is broken, but here is the page (with working download) from the Internet Archive. http://web.archive.org/web/20090316092154/http://mpowers.net/executor/


4- Advanced Installer

Advanced Installer lets you create Windows MSI installs in minutes. This also has Windows Vista support and also helps to create MSI packages in other languages.

Download: http://www.advancedinstaller.com/ Let me know other tools that you have used to convert JAR to EXE.

JWrapper allows you to convert java to an exe or otherwise native app on the main platforms (Windows Linux, Mac) for free. It runs on any OS, supports built-in code signing and auto-updating, and it can optionally bundle the JRE in a very small (heavily compressed) package. – AntonyM Feb 20 '13 at 11:54

JarToExe is a 30 day trial... – 0x6B6F77616C74 Jul 26 '13 at 13:00

lets see, JSmooth was last updated in 2007. This is 7 years ago. This is like 1000 years in humans age. JarToExe seems to be still active. But no trial version and costs $145. Executor link is dead. Advanced Installer is for making .MSI, no mention of Java on the site, and it looks like marketing web site. This is a really useful answer. No open source software anywhere. – Nasser Mar 8 '14 at 20:36

visit regilanj.wordpress.com/2017/11/19/… for pictorial representation of converting .java to .exe using JSmooth – Maria Irudaya Regilan J Dec 18 '17 at 4:58

@DmitryLeskov, do you have any plans on updating this list? I suggest couple changes as of April 20, 2018. I.e. RoboVM site is not even opening. GCJ page is also not opening as well. There is some information here gcc.gnu.org/wiki/GCJ but it appears it's discontinued. Launch4j's status is (I'd say) "barely active", You can already download JRE 10, but launch4j still don't have support for Java 9 version detection (feature request since 2016 sourceforge.net/p/launch4j/feature-requests/107) and it's not even scheduled for next release. – Sergey Karpushin Apr 21 at 0:40

I would use GCJ (GNU Compiler for Java) in your situation. It's an AOT (ahead of time) compiler for Java, much like GCC is for C. Instead of interpreting code, or generating intermediate java code to be run at a later time by the Java VM, it generates machine code.


GCJ is available on almost any Linux system through its respective package manager (if available). After installation, the GCJ compiler should be added to the path so that it can be invoked through the terminal. If you're using Windows, you can download and install GCJ through Cygwin or MinGW.


I would strongly recommend, however, that you rewrite your source for another language that is meant to be compiled, such as C++. Java is meant to be a portable, interpreted language. Compiling it to machine code is completely against what the language was developed for.

+1 for being the one comment that (correctly) answers in the affirmative. I don't know if GCJ supports everything the conventional classfile/jvm combo does, but it's definitely worth a try for a "simple program". – Edmund Jan 6 '10 at 8:50

@SjB GCJ does compile to native executables that do not require a JVM. – Mark Jan 6 '10 at 8:55

@Mark - they don't require a separate JVM, but the libgcj libraries are effectively a JVM. – Stephen C Jan 6 '10 at 11:00

> Java is meant to be a portable, interpreted language. I really don't think that Java is meant to be interpreted. – cubuspl42 Jun 16 '16 at 18:55

@cubuspl42: In hindsight, and after learning more over the years, I agree. Languages aren't meant to be executed any way or the other. That's more of an implementation detail. Python is typically interpreted, but compiling it to C doesn't violate any spec I know of. However, It does, in some cases, obviate some of the intended design goals and benefits of the language. If you're looking to use one of your tools in a way that's extraordinary and unconventional, it might be worth thinking about whether or not it's the best tool for the job. – jakogut Jun 17 '16 at 22:47

I use launch4j


ANT Command:


<target name="jar" depends="compile, buildDLLs, copy">

<jar basedir="${java.bin.dir}" destfile="${build.dir}/Project.jar" manifest="META-INF/MANIFEST.MF" />

</target>


<target name="exe" depends="jar">

<exec executable="cmd" dir="${launch4j.home}">

<arg line="/c launch4jc.exe ${basedir}/${launch4j.dir}/L4J_ProjectConfig.xml" />

</exec>

</target>

I like this one as it also works on other platforms – willcodejavaforfood Jan 6 '10 at 9:24

launch4j runs the JVM as a separate process, so shows up in task manager as javaw. – NateS Nov 1 '14 at 22:18

This answer would be much better if you had included the contents of L4J_ProjectConfig.xml – Stijn de Witt Feb 6 at 19:11

I usually use a bat script for that. Here's what I typically use:


@echo off

set d=%~dp0

java -Xmx400m -cp "%d%myapp.jar;%d%libs/mylib.jar" my.main.Class %*

The %~dp0 extract the directory where the .bat is located. This allows the bat to find the locations of the jars without requiring any special environment variables nor the setting of the PATH variable.


EDIT: Added quotes to the classpath. Otherwise, as Joey said, "fun things can happen with spaces"

You should really quote your classpath. Otherwise fun things happen with spaces. – Joey Jan 6 '10 at 9:02

We have found Jsmooth to be well-working and easily scriptable with ant under Linux. You may want to use one-jar (also easily scriptable with ant under Linux) to collect a multifile application in a single jar first.


We primarily needed the easy deployment of the EXE combined with the "hey, you need Java version X, go here to download" facilities.


(but what you most likely need is the "Runnable jar" / "Executable jar" facility in standard Java).

The thing you can do is create a .bat that will execute the .jar file created, checking if there is a JRE present.


From Mitch useful link (source)


java -classpath myprogram.jar de.vogella.eclipse.ide.first.MyFirstClass

This can be used into your batch...

Using a batch file has the problem that a console window will pop up. Which isn't nice when you start a GUI program. – Joey Jan 6 '10 at 8:26

Geez. Is that namespace hierarchy deep enough? – Alex Budovski Jan 6 '10 at 8:36

Taken from the link Mitch (post deleted now btw) gave. I don't really think it's the point here. – Vincent B. Jan 6 '10 at 8:46

Well an exe file can be created to do this stuff with c++ like Eclipse has. – JCasso Jan 6 '10 at 9:06

There is a small handful of programs that do that... TowerJ is one that comes to mind (I'll let you Google for it) but it costs significant money.


The most useful reference for this topic I found is at: http://mindprod.com/jgloss/nativecompiler.html


it mentions a few other products, and alternatives to achieve the same purpose.
