By using eclipse export wizard, you can get executable jar files. But the jar file can be only launched by using command lines. Apparently, this is not a good option for most regular not-java-programmer users, especially if the program requires user’s input to proceed. We need a program which can be started by double clicking.
To convert .jar file to windows executable file, there is a good tool called launch4j. You can easily convert a jar file to exe, then your users can double click the icon and start the program.
Here is a snapshot of this tool:
How to use launchrj is very straightforward and it’s free without any strings attached.
The following is some other features it has:
- JAR files can be included into an executable file;
- Execute Java applications with any current directory;
- Java applications can make use of file type association;
- Java applications are viewed as native Windows programs (and you can create Windows shortcuts for your Java application in the Start menu or on the desktop);
- Use the icon (.ico file) of your choice or design for your executable;
- Fully localizable messages of the executable
As you will see in my later post, there is a a good eclipse plugin — fat jar which convert all java files to one jar file. You can first use fat jar to get one jar, then use launch4j to convert it to .exe file.
