Puppy Linux Discussion Forum

Evening, guys'n'gals.

I'm well aware that some of you won't touch Java - runtime OR apps - because you perceive it to be a huge security risk. Be that as it may, there's still no getting away from the fact that it's one of the most long-running (and convenient) ways to run any given app, cross-platform.....without the need for re-coding/re-compiling.

And there are, even now, an awful LOT of Java apps still out there.....often tucked away in the most ulikely of locations. I have quite a number, some of which I want to share with the community over the coming days. Phil B. recognised this fact, which is why he started a Java apps thread over at Murga some years back.

To "power" your Java stuff, we'll start off with the presently-available JRE runtime, packaged as SFS. This is currently at 1.8.0_333 - more commonly known as 8u_333.....

32- & 64-bit packages can both be found here:-

https://drive.google.com/drive/folders/ ... sp=sharing

I'm also making available a copy of Richard Erwin's Java Information Utility; this lets you keep an eye on & configure your JRE, once installed. After loading the SFS, once this has been installed it will remind you that you need to re-boot before Java is fully activated & recognised by the system (in case you didn't already know as much)..!

This can be found at the same location as above, and is a "no-arch" package.

FYI :-

For those of you who aren't aware, and may have visited the Oracle Java download page, and wondered why I'm not offering Java 17 or 18 (or wherever it's got to ATM), it's quite simple. Release numbers for the JRE runtime and the SDK developer packages are NOT in "lock-step"; although the development package may well have hit 18 (or whatever), v8 update_xxx is still the newest end-user runtime.

More to follow.....

Mike.

Thanks, Mike, for the applications. I'm one of those folks who thought Java was generally unsafe so having looked for apps which might be useful. But I do have one I run occasionally as there is nothing otherwise comparable. So, from time to time I download the latest version of Java. And that leads to the following question: Is java always backwards-compatible?

By the way, I recently stumbled upon a gender-neutral, politically correct, friendly plural for a group of humans: folks.

@mikeslr :-

I'm no expert, Mike, but AFAIK Java is always backwards-compatible.....at least, it is in MY limited experience. The only release that I ever found misbehaved itself was 8u181 or 8u191, around 18-21 months ago; they made a balls-up with one of the network modules, and it temporarily affected PaleMoon's ability to run!

I never did find out what caused it; either a new Java release came out - OR a new release of PaleMoon - and the problem henceforth disappeared into cyberspace.

OpenJDK17x64
https://jdk.java.net/17/
Tested on Slacko64 6.3.2

SFS made with Utility / Get Java Runtime / Development I only had to rename the file from:

openjdk-17_linux-x64_bin.tar.gz

to

jdk-17u352724-linux-x64.tar.gz

mikewalsh please make your own sfs for this JDK and add link in first post

Download java from oracle without login:

Here is most recent 8u301, 11 and 16:
https://gist.github.com/wavezhang/ba842 ... nt-3821188

Current release at the Drive - 8u333

32- and 64-bit SFS packages available. Link as above in post #1; navigate through and help yourselves.

Enjoy.

Hi @mikewalsh,

the link in your post #1 leads to the "old" 8u291 packages (not 8u333) ...

Sorry about that. I had a re-organise of that particular folder.......and simply forgot to update the links. All fixed now.

Cheers.

@puppy_apprentice

Hi there

Can you let me know which utility you used to convert the zipped file into a working SFS?

I am using Fossapup64-95 .......... if that makes any difference?

Thanks in advance

This script was in older versions of Puppy Linux before Slacko 7.0 and Bionic.

Right, gang.

I'm a bit slower getting these out nowadays.....but here are SFS packges for the current JRE : 1.8.0_371, or 8u_371.

Available from the main link in post #1. Load.....and re-boot, so Java is then available.

Mike.

@Jasper :-

Me, I download 'em from here:-

https://www.java.com/en/download/

.....then use UExtract to unzip them. Very straight-forward. And then just build an SFS to put it in /opt.

The script/utility that puppy_apprentice has forgotten to link you to was written by Richard Erwin (rerwin). It basically downloaded, unzipped, installed and did everything else required, including all sorts of "ifs", "thens", "what-ifs", "maybes" & all sorts of other cross-checks. There's also a standalone utility for the Java 'Control Panel', though you can find that one alongside the SFSs on my Google Drive at the link in post #1.

Mike.
