A new version of jPortable (formerly Java Portable) has been released by jPortable (32-bit and 64-bit) allows you to easily install the Java® runtime engine to your device for use with portable apps like LibreOffice Portable and legacy versions of Mozilla Firefox, Portable Edition (in 32-bit mode), and Apache OpenOffice Portable, all without any Java runtime on the local PC. It's packaged in Format for easy use from any portable device and integration with the Platform. It's freeware for personal use. Business use now requires a license from Oracle.

Update automatically or install from the portable app store in the Platform.

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.

jPortable Launcher

In addition to using jPortable with portable apps packaged in Format, you can also use our jPortable Launcher to run Java apps in JAR format. It will even automatically portablize the settings of many Java apps.

Story Topic:


Has happened to you that, having the both JRE (x86 & x64) in the same PAF, the update process create a wrong JAVA folder order?
<DIR> App
<DIR> Other
<DIR> jre-8u321-windows-i586\bin
<DIR> jre-8u321-windows-i586\legal
<DIR> jre-8u321-windows-i586\lib
<DIR> Data

So, I have to move the 'bin', 'legal', 'lib' from the 'jre-8u321-windows-i586' to the JAVA's PAF Root folder to make PAF's JAVA Based apps works... has happened that to you?

When this happens, something prevents the portable installer from moving those directories after they were extracted from the downloaded local installer. Usually an antivirus or slower drive. The simplest thing to do is delete the CommonFiles\Java directory and reinstall.

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