After completing your project in Eclipse, you will want to make the project an executable application. The easiest and most common way to run a Java project is to create an EXE file from the project. This article will guide you through converting a JAR file into an EXE.
Step
Method 1 of 3: Exporting Files from Eclipse
Step 1. Right-click your project, then select Refresh or press F5 to ensure that all project code is the latest version
This step will prevent conflicts when you export the file.
Step 2. Right-click your project, then click Export
Step 3. Open the Java folder, then double click the Runnable JAR file option
Step 4. Set the JAR file specifications
Select the main class (the class with the main method) from the Launch configuration menu.
- After that, select the Export Destination directory from the Browse button, or enter your desired directory manually.
- Make sure you click on the Extract required libraries into generated JAR option. Ignore the other menus in the window, then click Finish.
Method 2 of 3: Creating Icons
Step 1. Find or select the appropriate image for your program
This icon will be seen by users often because the user will click on the icon to open your program. Choose an icon that is easy to remember or that fits your program. Make sure the image size is 256x256 pixels.
Step 2. Visit

Step 3. Enter the URL of the image, or select an image from your computer to turn the image into an icon
After that, click the Go button.
Method 3 of 3: Creating an EXE File
Step 1. Download Launch4J from
This program is designed to compile your Java projects into EXE files.
Step 2. In the first text box, enter the location where the EXE file is saved, or select a location using the buttons provided
Make sure you put the.exe extension at the end of the file name.
Step 3. In the second text box, select the exported JAR file from Eclipse
Step 4. In the fourth text box (Icon), enter the location to save the icon, or select the icon file with the available buttons
This step is optional; if you do not enter an icon, the operating system will display the default icon for the EXE file.
Step 5. On the JRE tab, select the Min JRE Version version, then click "1.4.0" to make sure the user can run the program with the appropriate Java version
You can choose another Java version, but generally, 1.4.0 will suffice.
Step 6. Click the Gear-shaped Build wrapper button at the top of the screen
Step 7. Name the XML file as desired, then click Save
This XML file is a standard XML file. After that, your EXE file will start to be created.
Tips
- Make sure the size of the image to be used as an icon is not larger than 256x256. Select the image file in Launch4J.
- Make sure all the files you select have the correct extension.
