Create Windows executable from Java applications.

editor's review





Launch4j is a software utility that allows users to wrap Java applications into Windows native executable programs. We all know how tiresome it can get to open a Java-based application on Windows, and this is why Launch4j comes in handy for all users who want to run JAR files as regular Windows programs. You may convert Java applications on Windows, Linux, Mac OS X and Solaris.

Although the user interface is straightforward, there isn’t a help menu included in the app that could make the beginners understand how this program works.

You cannot drag and drop the files into the main window of the app, so you should add them using the built-in browse option. There are several configuration settings included in the app by the developer that make the entire process easier and faster. You can make Launch4j search for a certain JRE version or use a bundled one by specifying the initial and maximum heap size. If the app is not able to open a JAR file or some errors occur during the process, then it automatically opens the Java download page or a support website.

The program also allows users to simply launch the Java application, without having to convert it into a Windows appropriate file format.

Moreover, you can make the app display native JRE splash screen in BMP format until the program manages to open the Java applications.

All things considered, Launch4j is a handy tool that can help you wrap Java based programs into Windows executable files. Although it cannot be described as the most powerful tool in its category, it packs enough features for converting or opening Java based applications pretty quickly.
