jPortable Launcher 4.0 (formerly Java Portable Launcher) has been released. jPortable 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 This release has an improved launcher and installer, adds support for the Java Runtime Environment within the newly-released jdkPortable, and adds an OS check to the jPortable Launcher 64-bit variant. It's packaged as a portable app, so you can take your browsing experience with you and it's in PortableApps.com Format so it can easily integrate with the PortableApps.com Platform. And it's open source and completely free.
The Java Portable Launcher allows you to easily run Java JARs using the Java Virtual Machine installed on your PortableApps.com-enabled device using jPortable. It can also use the JRE within jdkPortable. 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.
PortableApps.com Installer / PortableApps.com Format
jPortable Launcher is packaged in a PortableApps.com Installer so it will automatically detect an existing PortableApps.com installation when your drive is plugged in. It supports upgrades by installing right over an existing copy, preserving all settings. And it's in PortableApps.com Format, so it automatically works with the PortableApps.com Platform including the Menu and Backup Utility.
