<
install4j comes in two editions, the Professional Edition and the Enterprise Edition. To check the differences between the two editions please see theedition comparison. Features that are available in theenterprise edition only are marked as such in the the following list. install4j offers the following features:
construction of a distribution tree install4js GUI allows you to
freely define your distribution tree
In each directory of the distribution tree you can include the contents of entire directories or single files from arbitrary directories on your disk. Thedefinition view and the results view give you fullcontrol over the files that will be distributed byyour installers.
handle platform specific differences
install4j offers convenient include/exclude mechanisms that let you tailor your distributions in a platformspecific manner.
define file rights for Unix, Linux and Mac OS X
For each element of the distribution tree, you candefine custom access rights for installation on Unix like platforms.
define a fine grained uninstallation policy
For each element of the distribution tree, you can determine whether you want the uninstaller to removeit or not.
define the overwrite policy
For each element of the distribution tree, you can seta different overwrite police that determines what install4j will do when it has to overwrite files during an installation.
define installation components
You can define groups of files and directories that constitute separate installation components. You canoffer the user to select only certain components forinstallation.
compilation of native launchers install4j launchers have the following features:
Customized JRE/JDK detection
The executable can detect appropriate Java JREs and JDKs on the target system. You can also distribute your own JRE on demand (see below). The search sequence, error handling and supported JRE/JDK versions are fully customizable.
Flexible classpath construction
The classpath for your Java application can be fullycustomized to scan directories for JAR files, includespecific directories and archives as well as insert environment variables. Customizable error handlingallows you to interrupt the startup sequence with aspecific error message instead of obscure NoClassDefFound exceptions later on.
GUI, console applications
install4j lets you compile GUI applications or consoleapplications with an associated terminal window.
Service launchers (enterprise edition only)
Services (or daemons) are fully supported by install4j(enterprise edition only). For services, install4jgenerates service executables on Windows, startupitems on Mac OS X and start/stop scripts on Unix/Linuxplatforms.
Custom working directory
If required you can adjust the working directory to a specific directory relative to the executable. This isespecially helpful for console applications which canbe invoked from arbitrary directories. This way, youdont need to define fragile environment variableslike MYAPP_HOME.
VM parameters file
For every executable, you can create a user editableVM parameters file. In this way, users can adjust VM properties like the maximum heap size.
Windows version info resource
install4j can generate a version info resource entryin Windows executable. This version info is displayed for example in the property dialog of the Windows explorer. If you wish to obtain the "Designed forWindows" logo, this is an important requirement.
Splash screen
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 yourJava code, this status information can be easilyupdated with one simple call. With install4js "auto off" mode activated, the splash screen is hidden, as soon as your application displays a window.
Redirection of stderr and stdout
The standard output and error streams can be redirected to customized files. This gives you accessto valuable information like an exception stack traceon stderr that would otherwise be lost for a Java GUI application.
Startup failure detection
No more flashing terminal windows and GUI applicationsthat hang without displaying anything. install4j executables can monitor a stderr output file and display a dialog with helpful information to inform about startup failures.
Custom icon
Install4j uses two image files to create the icon for your launcher. install4j creates Windows icons thatare optimized for Windows XP and also have optimal display properties on older versions of Windows. Youcan also specify your own Windows icon file.
Custom process name and taskbar grouping on Windows XP
On Microsoft Windows, install4j launches your Javaapplication in such a way, that the install4j executable and not java.exe or javaw.exe will appear in the task manager. In Windows XP, the task bargrouping will display the name of your executable and the associated icon, instead of the non descript terminal icon and the string "javaw".
Application bundle on Mac OS X
On Mac OS X, install4j executables are part of a proper application bundle. You can specify a Mac icon for your application.
Window manager integration for KDE/Gnome

users to easily place a shortcut on their desktops and
desktop menus.
