Dear friends
I came to know that one can build exe files from java application. How this is possible? According to me there is no such method in java to cerate exe files. However Microsoft used to provide a free system development kit (SDK), for Java, which includes the jexegen tool. But one need install Microsoft Java Virtual Machine to run such application.
Some people suggest InstallAnyWhere.

The way i use is a program called JSmooth
dont know the website but you can just goooogle it
It takes all the class files and packages them in an exe file, and when executed searches for the JVM, so you still need to have the JVM on the users computer, but it also has an option to include the JVM ( that would be a big file )
anyways check it out, might suit your needs as long as ur programs arent too big....
note: i think there is a big in there, you might have to put all ur class files in jar files and have it read them from the jar file for it to work correctly, you might even have to set up the manifest in the jar file to make it be able to execute as a jar if you want it to execute as an exe, not sure though you should test around with it

Thanks BitShift
I found JSmooth. But the problem still remains. Say for example I give a java application wrapped with JSmooth to a customer who doesn’t have internet connection. JSmooth will search for internet connection which is not present to download Java virtual machine. So he might have to install JVM manually. Therefore the problem still remains.

hi, first of all, java is not a compiled executable. you can only change how it was packed either in classes or in jar files.
some offer tweaks on how to create an exe file but that is way beyond what i am to tell you.
since java is not a compiled software, it needs to be parse or run in a translater which is the java virtual machine. you can have the java virtual machine packed with your distribution software and write an installer script that will also install the virtual machine.
there are alot of installer scripting software available so i will not pick one. you can google on how to create an installer with executables inside that will automatically be run or setup after install.
--
PS. java is just translated in order for this to run on all machines, dont use microsoft.. microsoft java runs on all machines with windows as they say but that is not true. have a microsoft java software that wont run on a certain version of windows.
no problem with sun java and / or eclipse java in anyway though.
ciao!

genuinely asking for a Java to native code compiler, or whether you are
simply asking how to write stand alone applications, instead of applets.
Java uses a runtime technology called a JVM - a Java Virtual Machine.
The applets you ran in your browser worked because the browser was able
to load and run a JVM (as a plugin). To write software that does not
require a browser to run, one simply calls the JVM directly, passing it
the name of the class with a special 'main' method. To create user
interfaces you can use classes like Frame in AWT (or JFrame in Swing)
to create windows. The rest of the UI code looks pretty much the same
as an applet, except you are adding it to a Frame object, not an Applet.
Sun's JVM is called 'java' (or java.exe on Windows), and can be run from
a shell/DOS prompt like any other program of that type. Running it
without any options will usually make it print some helpful usage
information.

I think JSmooth has an option to include the JVM
and even if it doesnt im sure a program out there does, gooogle for one, im sure some1 has made 1 along the way
you cant be the only 1 with this problem

I guess you have misunderstood me. My purpose of asking this question was suppose I have built an accounting software using java and I want to sale it and if my customer does not how to install java. He might does not have even jdk rather JRE. In such cases deploying the software would be very tough. Either I have to personally install the software or the customer has to hire a professional to install the product. That is why the issue of deployment becomes as important as creation. By packing the software with installer along with the classes and JVM the deployment will be much easier and end user friendly.

If this is the case then you should include a JRE that is compatible with your software when you sell it.
If the program you have written needs to be installed on the users PC, in the installer you can write a script to detect to see if they have a JRE installed. If they don't you can have that installer pause and have it automatically open the installer for the JRE that you included.
You should try and do something crafty like this.
Also most computers come with a JRE installed now. If you look around at desktops being selled that come preinstalled with windows and other packages, almost all of them will have some version of a JRE installed, its pretty standard since so much of the web uses Java.

Yep - BitShift spelt out the correct installation method for you. There are plenty of free installer software around - one of the best being NSIS Installer, which is immensely customizable using it's own powerful scripting engine.
You should include a copy of the required JRE on your installation CD. You can easily detect the presence/absence of the JRE on the user's computer using NSIS and then fire up the JRE installer automatically if needed.
You can grab NSIS at: http://nsis.sourceforge.net/Main_Page

To Answer the origonal question:
"How To convert java source code into an executable (.exe)"
The Answer is simple, Compile it ! ( just like any c/c++ source code )
i dont think SUN have a native java compiler ( javac convers the source to bytecode, to be later run by an interprever ( java ))
However, native java compilers do exist.
For Example GCJ ( part of GCC, the GNU Compiler Collection )
Nativly compiling a java application has its advanatges, for example, you dont need to have JRE installed, but you lose the abbility to "compile once, run on any operating system"
good luck.

You have to integrate your application with a file named javaw which allows the application to be as a free independent program rather than running from the command prompt java.exe
or you can make a bat file to run the program

Converting Java application to EXEHow To Create Exe File In Java?
Instead of using a java exe launcher, a Java application could be compiled to native code (exe file) which doesn't require a JVM at all. One of such tools is JCGO, a Java to C translator. The produced C code is highly portable (Windows, Linux, Solaris and FreeBSD on i586 and amd64 are, at least, well supported). See more information (and the compiled sample applications) at the developer's site - www.Ivmaisoft.Com/jcgo/

for all the people out there that want to learn what exe natev code is this message is ruf and I typed it as fast as I could so if there are spelling mustakes pleaz don't be angry first off ill teach you how to for real to create a exe code in java that runs frist ill teach you string datastring data is a set of bytes read by a program or function that draws each binary code as diffrent leters so ill teach the simpal com system that is emulated by exe code that is 16 bitdon't for get all the codes that I do are in hex60 small leters40 capital letters20 space bar0d 0a line breaknow to make letters you use the elthabet abc's you count the number of each abc a=1 b=2 c=3 you get the idea there are 26 abc's now "j" is the 10 letter in abc's now in hex its "A"now 60+A=6A makes small "j" 4A makes capital "J"now a com 16 bit code runs in ram not off the memory off the computer when you run your exe every hex or binary bits will all be writen into ram for spead becuase of the ms dos app ms dos stands for microsoft digital operating system this runs the code it starts by puting all your codes at offset address 0100 in the segment address of where your program runsthe string data in your exe will be lowcated some where in ram you can use an intrupt function to draw your string data but first you nead to set the registers to where the string data is so this int function can find the data the registers are a part of the processor of the computer that store data and flags but its limited now the int function reads the registers to find the string datanow the hex code CD is the intrupt code now if you use CD folowed by the hex code 21thats a dos intrupt code now ms dos can draw strings get the date and time right to tell CD 21what dos function to use you use the AH register in the processor witch the dos program will read and use it to tell it what function to use AH=09 print a stringAH=08 wait for key input key is stored in AL the AX register has 2 bytes AH AND AL both hold 1 byteAL is the first byte of AX AH is the Last Byte of axto change the ah value you use the hex code B4 folowd by what to set ah toB4 09 the draw string function of the CD 21 codeB4 08 the key press function of the CD 21 codenow the DX register is used to tell the dos intrupt where the offset of the string isto set DX you find the number offset to your string then you pad it whith 0's if its not 4 in lengththen you take the 2 first hex numbers and put them infront of the others coz the computer reads things backwordsnow to set dx to that value of yours you use the code BA folowed by 2 hex code to the string make shere thay are in reverse oder and are paded so BA AA0A would normaly be 0AAA then take the pading out = AAA now thats all there is to itand the code CD 20 terminates your programand the end of your string should allyes end whith the code 24now I will show you how to write your first code B4 09 BA ?? ??

computers are not magic I uset to think thay where and plzz do not mess whith this post coz my last post on whiting bmp pictures worked but then when I go to compile it it qwit working Please leave this code for people that realy whant to lean how to write a exe with java this java file must be saved in a file named hex.Java and compiled useing the javac compiler by damian recoskie I simplified this tutoral the besti could but I don't feal like makeing a deatiled tutoral on every function and how to use stuff that works like a if in java and bilding a game in pure native binary code I have writen a few games in binary binary is the same as hex there just numberd difrently
0100 in hex is 4 you calculate binary numbers like this
8 4 2 1
1 0 1 0=8+2=10
1 1 0 0=8+4=12
0 0 0 1=1
0 0 1 0=2
0 0 1 1=3
0 1 0 0=4
0 1 0 1=5
sound music to any kind of mead its all binary the digital signal is converted to an analog signal for sound it may sound complicated but its not by damian recoskie that is my real name
