What is exe4j and why do you need it?
Exe4j is a software tool developed by ej-technologies GmbH that creates Windows executables that invoke your Java applications. It is included for free when you purchase install4j, a multi-platform installer builder for Java applications. Exe4j is useful if you want to create a Java launcher without an installer. All license keys for install4j work with exe4j. Standalone licenses are also available. Without a license key, exe4j can be evaluated without any time limit, but the executables will show evaluation warnings and services will stop after 30 minutes.
Exe4j is a Windows launcher generator for Java applications
Exe4j allows you to create Windows executable files that can run your Java applications like a regular Windows program. You can choose from three types of executables: GUI application, console application, or service application. You can also select from two modes of compilation: regular mode or JAR in EXE mode. In regular mode, exe4j is a pure launcher and relies on all JAR files and resources to be present in the distribution. In JAR in EXE mode, exe4j includes the JAR files specified in the classpath configuration into the executable. In this way, you can distribute your application as a single executable file.
Exe4j helps you integrate your Java applications into the Windows environment
Exe4j provides various features and options that help you integrate your Java applications into the Windows operating environment. For example, you can:
Set the application icon, the splash screen, the version information, and the digital signature for your executable file.
- Specify the Java home directory, the classpath, the main class, the arguments, and the environment variables for your Java application. - Control the service options, such as the service name, the display name, the description, the start type, the dependencies, and the user account for your service application. - Define the error handling behavior, such as the exit code, the error message, and the log file for your executable file. - Customize the messages and dialogs that are shown to the user during the execution of your executable file.
Exe4j offers various features and benefits for Java developers and users
Exe4j is designed to make it easy and convenient for Java developers and users to create and run Windows executables for their Java applications. Some of the features and benefits of exe4j are:
