Creating EXE in Java

It is possible to create .EXE files in Java?
Thanx

Java does not produce .exe files. The are various (Windows specific)
tools that do - compilers - but javac isn't one of them.
If you mean the question more generally: "How do I create files that the
user can run by double clicking them, or typing their name at a
command prompt?", then the usual method is to create a .jar file.
In Windows double clicking a .jar file usually results in javaw being run
with the .jar file as its only argument. The application contained in the
.jar file then runs.
Creating .jar files - complete with lots of examples - is covered in Sun's
Tutorial here: http://java.sun.com/docs/books/tutorial/deployment/jar/index.html
(Like any document or executable a java applcation can be launched
from a .bat or .cmd file, but if you don't actually need the fine control that
these offer, .jar files are the way to go.)

Create .exe file for core java project

how can i create .exe file or wrapper for my core java project

To be honest with you this is going to be very difficult at best.
And I'm not sure it's entirely realistic or legal. You'll need to install Tomcat and MySQL and all your stuff...Haven't ever tried doing so, but I think it might be quite possible sollution...
There's a preconfigured version of Tomcat, that you simply unzip on the drive (so there's no nned of running installator).
If OP would use some MySQL server's clone, that needs no installation (some time ago i was looking for thing like thatand found couple of those).
All configuration (installing services etc.) as well as copying JSPs and other stuff to Tomcat dirs can be made with script files (.bat or whatever) or under another java application that will run all the commands...
As cotton.m wrote... if it works, it's going to be hell lot of work...

How to create .exe file of the java program you create?

This must be the qustions asked several time on the forums.So here it is again.
This sounds absurd to some developers here cause you'll say just create jar file and distributre to usr but sometimes there is not possiblity of having runtime environment in windows computers.So if we can bundle the enviroment and the setup together then packing into exe and then distribute like most of commercial java application sounds better.But the problem is how to do that?
Ok creating exe will increase the size but that doesn't matter,if there is any freeware tool to accomplish just that?

Can any one guide me how to proeceed pls...

Microsoft SDK for Java 4.0 (free to download
on www.microsoft.com).
It includes the program "jexegen"
command:
jexegen /main:MainClass /out:Program.exe *.class /W
1. MainClass : the class where the public void main(String[]args) method is in.
2. Program.exe : the exe-file to be created.
3. *.class : all the used class-files.
4. /W : he won't show the black box of the MSDos-prompt with
windows applications.
IMPORTANT !!!
Even after you made an exe-file you will still need
a Java Vitrual Machine on your computer to execute it.
Hope this helped

.exe in java?

grahhhhh!!!!
Can you make a .exe file using java, or does the "platform independent" quality prohibit that. Basically, I want to create a simple java program that I can put on a disk, and load to another computer (without a compiler) and be able to run it. How do I do that?
Thanks,
Dave

As long as the other machine has the java runtime environment (jre), then you can easily make single file, single double click applications (just like .exe). All you have to do is after you have all your .class files, put them in a .jar file. You have to make a small text file (called a manifest file) to tell it it is executable, but that is easy. There is a whole section on jar files in the Docs and Training section.
Hope this helped.

Creating .exe file

Hello
Is there any method by which I can create an exe file for distribution of my application. The current method for distribution is to make a jar file and then to run it using java -jar option. But it is a bit difficult for a novice user. If someone can help me out and tell me a method for creating exe file for my project.

I found Jet pretty much unusable for larger applications
The compiler it uses is buggy, and doesn't manage memory well at all, leading to frequent unrecoverable crashes. and it's SLOW
Far easier to download a java launcher application, there are several available, or fork out for InstallShield for Java for example.

Creating .exe installers from Creator

Though it is not recommended to distribute Java applications as .exe files (Webstart and JARs being the preferred mode), will it be possible to create .exe executables of applications from Creator?
.exe installers are more familiar to many users than JARs.
Manish

Hi Manish,
Is the machine, you want to download the application to, a stand alone machine or a machine on the network?
If it is a stand alone machine you would have to install the App Server and then deploy your application. One thing to be noticed is that Creator is for building web applications. So, to me, it would not make any sense to deploy it on a stand alone machine.
If the machine you want to run the application on is a networked one, then you would only need to install the the appserver and deply the application on the server.
Bundling the appserver along with the application also has its other drawbacks. For one you would have an appserver for every application you are running on a server(assuming the appserver gets installed every time you run the executable.) Another issue could be the size of the bundle.
Hope this rambling of mine has cleared your doubts.
Apart from that I am not aware of any possibility of creating an executable or packaging both the app server and the developed application in one single bundle.
Cheers :-)

How to run geniatagger.exe from java

Launch4j for creating exe

Hi,
I am facing a problem while creating exe using Launch4j.
It is giving an error as it Could not findthe jar file specified when build.bat is executed.
The jar file is placed in the project folder along with build.xml and build.bat.
Could you please guide me solve this issue. Please let me know incase of insufficient inforamtion as I am using Launch4j for the first time.

Launch4j is not a product developed or endorsed by Oracle, and is probably not very widespread: a majority of Java developers (unfortunately) won't care about how the applications are installed and launched.
So you won't find a lot of help here. Instead, the likeliest way to get help on Launch4j specifically, is to turn to the Launch4j's project support: http://sourceforge.net/projects/launch4j/support
Good luck,
J.

It will help me a lot.
Thanks in advance
Amol Mali

Hi teda,
i'm assuming that you have seen my post that i did successfuly save report in user's personal category.
Actually the report is created in webi java panel using RE SDK and is saved in Report Sample Folder then i'm saving it in user's personal category by following code
string query = "Select SI_PERSONAL_CATEGORIES From CI_INFOOBJECTS Where "
                     + "SI_INSTANCE=0 And SI_ID=" + reportID;
                InfoObjects infoObjects = infoStore.Query(query);
                InfoObject infoObject = infoObjects[1];
                Webi wreport = (Webi)infoObject;
                ObjectRelativeIDs personalIDs = wreport.PersonalCategories;
            /personalIDs.Add(Convert.ToInt32(categoryID));
               infoStore.Commit(infoObjects);
But the report is presents in the Folder also and in user's personal category also.
I dont want the report to be in the folder (Report Sample) if i saved it in user's personal category.
How can i do that?
any idea.
Please help me.
Thanks in advance

Help with creating an animated java applet...

Hello, everyone! I'm working on a homework assignment for my Intro to Java class, and I'm having a problem I've never run into before. My assignment is to create a animated Java applet which displays an image of an alien spaceship which travels in diagonal lines across the applet area. My main problem is that when I try to compile my code, I get three "cannot find symbol" errors about my variable "alien." I can't figure out why declaring it as a class variable hasn't solved my problem. The errors pop up for the repaint() method, as well as the pane.add and the paintIcon. Here's my code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.Timer;
class DrawAlien extends JPanel
public class Alien extends JApplet implements ActionListener
ImageIcon alien;
public void init()
    Container pane = getContentPane();
    alien = new ImageIcon(getClass().getResource("alien.gif"));
    pane.setBackground(Color.black);
    pane.add(alien);
    Timer timer = new Timer(30, this);
    timer.start();
public void actionPerformed(ActionEvent e)
    alien.repaint();
}I've only posted the section which I think is relevant to my problem, but I can post the rest if anyone thinks it's necessary.
I'm aware that the code isn't ready yet in several other ways, but I don't think I can move on until I figure out what's up with the "alien" variable. I don't need anyone to write code for me or anything like that, I just lack perspective here. A couple hints in the right direction would be invaluable. Thanks!
Edited by: springer on Nov 25, 2007 10:46 PM

You can?t add ImageIcon into pane, you can do like below.
alien = new ImageIcon(getClass().getResource("alien.gif"));
    pane.setBackground(Color.black);
    JLabel label = new JLabel(alien);
    pane.add(label);

Getting error while creating exe file from my VI.

Hi,
I am trying to build the exe file of my VI. I tried to follow the instructions in Help ( Example: Building a
Stand-Alone Application) but instead of creating exe file, it is creating folder containing my all VI and VI from Application Builder.
Kindly Help me.
Thanks and Regards,

It sounds like you might have accidentally selected to create a source distribution instead of an application. That's different from an application. A source distribution basically makes a copy of your VIs into another location so that others can use them for VIs they create. When you expand the Build Specifications tree the icons indicate what kind of build you're creating. An applicaiton has an icon that looks like a tiny window with a title bar. A source distribution has an icon that looks like a folder with the Add function in the upper right:
