Java Runtime Environment makes possible running programs written in Java

Java software for your computer, or the Java Runtime Environment, is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, or Java download.

J.R.E. software package(s) (installs to /mnt/home/java)

Configuring J.R.E.

Go to: Edit > Preferences > Advanced > Enable Java

Go to: Tools > Options > Java > Add

Go to: Tools > Preferences > Advanced > Content > Enable Java
Click Java options. Click Choose to select the Java path mnt/home/java/lib/i386. Click Validate Java Path.


- Either via automatic installation using the above .pet software package
- Or, via manual installation:
1. Download Sun Java from I prefer to download it to /mnt/home to conserve my ram. If you want the latest revision you can just click the big download button, and then select the “Linux (self-extracting file)” not the one with RPM in the name. If you want an earlier version then click “Other Java Versions” and then “Archive Java Technology Products Download” under Older Versions. (One of my job sites, for instance, works best, or at all, only with 6 update 7.)

2. When the file is downloaded open a Rox window and go to the place where you downloaded Java. First, Right-Click the java file and then choose Permissions and Yes to make the file executable. Second, Right-Click -> Window -> Terminal Here.

3. In the terminal enter

(or whatever the name of the java file is). Don't forget the "./" to begin (that is period – forward slash, to indicate that the file is found in the current directory). You will need to scroll down with Enter to accept the license agreement and then the install program will create a folder named "jre1.6.0_14” or something like that.

4. Take that folder and place it at /mnt/home.

Blackdown Java 1.4.2_03 DotPup (20MB) by flavour (dotpups no longer supported in later Puppys)
Work the way as the dotpup above, except that it's much smaller (56MB decompressed). Don't be scared by the name of the dotpup, it's working :-) If you don't need sound, you can get this even smaller version: 11MB download by flavour and kirk. Read More
