The Java Portable Launcher allows you to easily run Java JARs using the Java Virtual Machine installed on your PortableApps.com-enabled device using Java Portable. 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.
Java Portable 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.
