Install4j is a useful application that was designed in order to provide you with an easy to use means of generating your own personalized native installers and application launchers for Java applications. Install4j excels in its ease of use, its extensive platform support and its powerful screen and action system.
For GUI applications, a splash screen gives the users of your application an optimum feedback about application startup. Textual status information about application startup and version information can be freely placed on the splash screen. From within your Java code, this status information can be updated with a simple method call. With install4j's 'auto-off' mode activated, the splash screen is hidden, as soon as your application displays a window. On Windows, the splash screen is native and is displayed immediately.
Java 6 splash screens are also supported. Form screens are the most flexible screens in install4j that allow you to quickly configure arbitrary installer or uninstaller screens. Form screens contain a number of form components that are aligned along the vertical axis. You can chose from a wide range of form components:. Labels and spacers.
We have a few internal applications at Neo which can be launched using ‘java -jar ‘ and I always forget where the jars are so I thought I’d wrap a Mac OS X.
Option selectors like check boxes, combo boxes, lists, drop-down lists and radio button groups. Sliders and spinners. Directory and file choosers. Password and text fields. Formatted text fields.

Text areas Form components have optional leading labels that are aligned for the entire form and are highly configurable. Actions can be added to each configured screen and are executed when the user moves to the next screen. This allows you to program the installer visually in the install4j IDE by wiring together screens and actions.
Install4j offers a wide range of pre-defined actions. Actions can also come from installed extensions or the configured custom code locations. At the heart of the action system are the 'Install files' and 'Uninstall files' actions that take care of the distribution tree, taking into account the user selection of installation components and downloading installation components if necessary. For file modification and installation actions that cannot be handled with the configuration of the distribution tree, a number of file operation actions are provided including:. Copying files. Moving files. Deleting files.
Setting the modification time of files. Creating symbolic links on Unix and macOS. Configuring file access modes on Unix and macOS. Configuring the owner of files on Unix and macOS.
Installing the contents of a ZIP file. Changing Windows access rights. Displaying a PDF file in a cross-platform PDF viewer.
