I\'m a Java beginner.
I already created a simple GUI application that display will \"hello world\" label.
But, how can I create an installer from .java or .j
I use a program called JSmooth. This turns java .jar files into executables. I then take those executable and create a installer using InstallShield. InstallShield allows you to create highly customizable installers. There is a free "Light Edition" that you can use. Very easy to do and very easy to add to build scripts.
Basically, you have to save your project in jar and then convert to exe, you can use jar4exe or other software. When you have the exe file, use an installer software like Inno Setup Compile or other. After all those stpes Your project will be ready to be install in windows, mac or linux platform. Good Luck.
You can use Ant task tool with InnoSetup and Launch4j under Eclipse IDE to create a professional-looking Windows-based EXE installer for Java-based program: How to create an exe file in java
