How to create the exe files for java application

How to create the exe file for java application?
got any software to do that?
Thanks

In terms of converting java applications into exe files, there are 3 schools of thought:
1) Instead of converting it to an exe, convert it to a jar file. Jar files are more portable than exe files because they can be double-clicked on any operating system. The caveat is that a Java interpreter must be installed on the target computer for the double-clicking to work.
http://developer.java.sun.com/developer/Books/javaprogramming/JAR/
2) Create an exe launcher that, when double-clicked, attempts to find a Java interpreter on the local computer and launches the Java application. The exe file is still double-clickable but whether your java application runs depends on whether a Java interpretor is installed on the target computer.

3) Create an exe launcher that bundles a Java interpretor. Same as above but when the exe file is double-clicked, it searches for a Java interpreter and if one is not found, it installs one on the target computer. The caveat is that the exe file would have an overhead of 10 MB in size for the interpreter.

4) Convert the Java application into a native exe file. The caveat is that if you use Swing for your GUI, it won't be converted. Also this option is still somewhat experimental.
Can't think of any free options right now.

How to use runtime.exe to activate the native file coping commands

How to use runtime.exe to activate the native file coping commands.(It might include using process(), and such.. but how?

Why would you want to do this? It's harder than copying the file in Java (by reading the file and writing it to a new file) and you'll need to write new code each time you want to port your code to a new OS.

How to create distributed .exe of any CVI project

How to create distributed .exe of any CVI project that we can execute in any system which doesn't have CVI installed

To have a CVI excutable running on a target system you must install the apropriate support libraries and modules on it: CVI integrates the ability to create proper installers that create the correct executing environment on the target machines. These functions are included in Build >> Distributions menu item: select "Manage distributions" and look into the detailed online help.
An overview on creating a distribution can be found in Using LabWindows/CVI >> Managing projects >>Building a project >> Distributing applications topic in the online help as well as in several forum threads and other documents on NI site: as an example, this one covers this topic for CVI 8.x

Thank you.

I need help how to create menu function for link to access file and allow user to save the file when click on it.
The file will keep inside server.AFAIK, you have to write a custom code to achieve this and Oracle does not provide this functionality.

How does the app know image folder (non class files) wrapped in jar file?

Hi,
I created an jar file, client.jar, which wrap all necessary files, including packaged class files ( in a hierarachy structure), image folder, properties folder, and ext folder (containing other jar files used). When I run the jar file, like
java -classpath c:\tmp\client.jar -jar client.jar
the app does not know where the images go and could not get the properties files. Actually the image and properties files are contained in the same file: client.jar. How can I fix this. I don't want to extract the jar file back to several separated folders and then run it.
Appreciate the help.

Unfortunately you have to make some changes in your code.. to find the pictures you need to replace:
ImageIcon pic = new ImageIcon("pic.gif");
with
URL url = MyClass.class.getResource("pic.gif");
ImageIcon pic = new ImageIcon(url);
where MyClass is the class which needs to load the resource.
I hope this helped you! /Pingu

How to create an object within the same class???

hi im just a newbie
i v been always creating an object from the main class..
but how to create an object inside the same class??
i got main and students class
the main got an array
Students[] stu = new Students[]
and i got
stu[i] = new Students(id,name);
i++;
but i wanna do these things inside the Students class..
i tried ..but i got errors.....
how to do this
.

javaexpert, :)
I really have no idea what you are trying to do since you say you've always been creating an object from the main class, yet you always want to create an object inside the same class.
I'll assume that you have an object in the main class that you are trying to access from the Students class.
If you are trying to access objects that are contained within the main class FROM the Students class, then know that there are two ways of doing so, one being static, and the other dynamic (look up definitions if unclear):
1.) make the objects in the main class both static and public and access the the objects using a convention similiar to: Main.object; It's important to note that Main is the name of your main class, and object is a static object. There are better ways of doing this by using gettter/setter methods, but I'll omit that tutorial.
2.) Create a new instance of the main class and access the objects using a similiar fashion: Main myInstance = new Main(); myInstance.myObject;
You should really use getter and setter methods but I'll omit the code. In terms of which approach is better, step one is by far.
I don't mean to be condecending, but you should really brush up on your programming skills before posting to this forum. This is a fundamenetal concept that you will encounter time and time again.

How to create an object of our own class by using Class.forName()??

how to create an object of our own class by using Class.forName()??
plzz anser my qustion soon..

Class.forName does not create an object. It returns a reference to the Class object that describes the metadata for the class in question--what methods and fields it has, etc.
To create an object--regardless of whether it's your class or some other class--you could call newInstance on the Class object returned from Class.forName, BUT only if that class has a no-arg constructor that you want to call.
Class<MyClass> clazz = Class.forName("com.mycompany.MyClass");
MyClass mine = clazz.newInstance();If you want to use a constructor that takes parameters, you'll have to use java.lang.reflect.Constructor.
Google for java reflection tutorial for more details.
BUT reflection is often abused, and often employe when not needed. Why is it that you think you need this?

Error while using .jar file instead of class file.

Hello friends,
I created a java class which are referred and called from other jsp\xml and java files. I compiled this java class and everything is working properly. However, I do not want to use class files but want to use jar files instead. So, I created a jar file of this class file by using the command "jar -cvf jarfilename.jar".I kept the jar file in its respective folder .Also, I removed the class file from its path, just to see that the jar file will work automatically.
Unfortunately, I am getting an error:
java.lang.RuntimeException: Component.createComponent(...) Component class not found: <java class path>. I also tried giving the path of this jar file in the classpath. This also does not seem working.
How to solve this problem?
Thanks,
Ranjith M.V
Edited by: RanjithM.V on May 11, 2008 10:34 PM

You probably populated the jar file incorrectly.
A common mistake is to include the path that you had on the classpath, in the jar file.
So a person will have a classpath like this: /foo/
And a class in a package bar, like this:
package bar;So that other classes would include the file like this:
import bar.TheClass;And the class file is on the filesystem like this:
.../foo/bar/TheClass.classThen they'll create the jar file including the foo directory, so if they list the jar's contents, they'll see the above (/foo/bar/TheClass.class). But this is wrong. It should start off so that the jar entries start with the top-level package names (like /bar/TheClass.class).
Maybe you've done that.

How to create and exe from a class file.

I want to create an application and want to distribute it. I am using simplw awt gui interface. I have compiled the program and have got the required class file. If I want an executable how can I go for it.
There are many files provided by java library which are exe but are created using java API eg. policytool.exe. Please Help.
Ashwini Bagga,
Jaipur(Rajasthan)

Java uses the JVM to parse the class files. It cannot be converted to a .exe file
but if you want to distribute it, i suggest you use InstallAnywhere which makes it into an exe installer.
In the end it still uses the virtual machine...
If i am wrong anywhere pls correct me thanks...

How to create smaller .exe file use JBuilder7

I am currently using JB7(EE), which can create native executable file for me. But I found it so foolish that add so many unneed classes to .exe(As I can use WinRar open it, but cannot change it).
Does anyone know how to reduce the .exe?
ps: As I use castor, so I had to include castor class in it, but I really don't want to add all of these to it.

In the Wizar you employ to make the native executable,
in the second step the Wizard ask you what to do with
the libraries you have employed in the proyect,
include all them include only the classes and
resources nedded, or not include. This way you'll be
able to control what is in you .exe file.
AbrahamYes, I had tried it, and tried every possible combination/permutation of the four choice.
But still bigger than it can be.
For example: I used castor.xml library, but JBuilder include all castor include xml parser, html parser, xhtml parser, etc.
As castor.xml --> castor.xxx(I cannot remember its name) --> castor.html-->...
So JB7 maybe confused by the complex deps.
So JB7 include ALL in my exe fiel.
It may be impossible to create smaller .exe file with normal way.
So anyone know any other way to create .exe file with the .jar file?
As I can change the content of .jar, but cannot to .exe.
thx for continous reply
