jPortable allows you to easily add a Java® runtime environment to your portable device. It automatically works with apps in Format like Portable. No Java® runtime environment needs to be installed on the local machine and no admin rights are required. The JVM will be downloaded directly from Oracle's servers as part of the installation process.

For the curious, Java 6 Update 31 changes the way the browser plugin works. It can't be made compatible with any existing portable browser releases. This update prepares jPortable to work with the new browser plugin setup. Browser releases for Firefox (10.0.2) and Google Chrome (all channels) that are already built and mirroring to download servers work with this new release as well as the older jPortable versions. A revision for Opera will be posted as well.

Sometimes, the impossible can become possible, if you're awesome!
