jPortable Launcher

run your Java® JARs anywhere

jPortable Launcher (formerly Java Portable Launcher) allows you to easily run Java JARs from your PortableApps.com-enabled device with the jPortable portable Java Runtime Environment installed. While it doesn't portablize their settings directly, it does work with any self-contained JAR that stores settings alongside itself or allows its settings to be saved to a portable location.

jPortable Launcher works best with the PortableApps.com Platform


ScreenshotjPortable Launcher allows you to easily run Java JARs using the Java Virtual Machine installed on your PortableApps.com-enabled device using jPortable. It can be installed into the PortableApps.com Menu where, when it is run, it will prompt you to select a JAR file to run. It can also be run directly by dragging and dropping a JAR file onto the JavaPortableLauncher.exe file.

jPortable Launcher does not portablize the settings of all your Java programs within JAR files. Some JAR apps will either store their settings alongside the JAR or provide an option to store the settings portably. Other JAR apps will look to the user.home setting and store data there. The launcher configures these to use your portable device for settings storage.

A variant that works with the 64-bit version of jPortable is also available:
