This is an example of what is occurring. This is contrasting 2 distros in the Identical same family and releases

This is showing LupuLibre where JRE PET was PPM installed and comparing LupuPLUS-Libre which has JRE built-in.

• with PPM manual selection of JRE, the ability to access JAVA from rhe command line remains over a save-serssion reboot.
  
• with JRE built-in, the abiilty does NOT remain, even when PATH variable is manually set

Hi.

Euh, sorry guys... I never use a pet or a Puppy sfs for java. Making those is a waste of time, IMO.

Save yourself a headache:
From the official java site, simply download a tar.bz2 file of the most recent java for "other" linux's, Unpack it and run it. It will install. all on its own, in /opt.

Then,
symlink (non-relative link) all the executables in /opt/java/bin to /root/my-applications/bin;
in ROX, specify "java -jar" in "default executable" for *.jar files;
finally, add "/opt/java/bin" (or equivalent) at the beginning of /etc/profile in the PATH line.
And voilà, you're ready to use java.
Just click on mucommander.jar, for example, or any *.jar file, and it will launch nicely.

I hope this is helpful.
BFN.

If a PET doesn't setup your java program for you (*.jar) you can run it from the command-line. See this!
I have been a user of those distro where I can add LibreOffice and JRE.

In addition, I have used @DPUP5520's several tools where he makes them easy to launch from the Menu.

• AngryIP
• IP Monitor

Hope this helps

Hi, gcmartin.

Sorry if I sounded off-the-cuff above, but I never had the problem of java disappearing on any of my Puppies or Muppies. Stange problem indeed.

Stanger still that one would have to create a *.pet ot *.sfs for it since it is so easy to install java, as I explained above.

I offer best wishes for your project.

BFN.

Thanks @Musher0

Your suggestion is a very plausible one for the community.

Many in the community focus on obtaining subsystems from the PPM as it intends to offer a central authority.

Also, many PETs are often embraced by Barry into the WOOF build for Puppy developers.

That's why this community does this...even for the easy ones. (But, as you can see, sometimes the easy ones don't exactly operate properly.)

I am not a developer. So even if I did do this, Barry knows that I am not a developer and my contribution would have little success reaching our wide audience.

But, others and yourself are regarded with high esteem.

I am just pointing out some of the issues that few are willing to articulate to the Puppy community. Most of what I share are reasonably easy obtains.

Hello, gcmartin.

Thanks for the explanations.

Sometimes this centralization makes me cringe a little because I believe it would simple enough to teach users to fetch the packages they're interested in outside the PPM -- which is nearly always limited to the distro packages Puppy X tries to "emulate" (wrong word, I know, but it's the only one that pops to mind right now). Whereas the world of Linux is so vast.

Moi?

Well, that's a good one! I'll take it while it passes! You made my day!

Why not use the SFS?

[musher0]

Hello.

Not to diminish your work in general or in particular, shinobar: I'm sure you spent hours preparing this sfs and maintaining it. And you have contributed greatly to the Puppy community.

But indeed, why create a sfs -- when good packages and localized intructions are available to download and install the latest java directly from java?

"Let's not multiply entities needlessly." (Ockham's Principle) It is, put in other words, a Puppy tenet, is it not?

My two cents.

Best regards.

@shinobar:

Glad you underlined the plus'ses of your java sfs. Localization, for one factor, is very important.

@Shinobar
I have 2 questions and a real PUPPY dilemma

Dilemma

• Puppy PPM does NOT use SFSs, to date

Questions

• I am not sure what is mean about Frugal or size, but, the JAVA support (when it works) doesn't seemingly impact system RAM usage, system performance, or system behavior. So, is the size when a PET installs from PPM versus when a SFS installs that different that it would have a dramatic impact on system usage?
  
• If one were to use a SFS to PET converter, would that have a negative outcome as far as the features you include in your SFS?

I'm just trying to understand all of this. And, I am NOT taking issue with anything that is shared.

Remember, the original problem of Playdayz's latest entry in an old one where the JAVA support cannot be accessed, normally, after a reboot of a Live media (save-session) system running in RAM.

For some reason, Pemasu's version was not doing this, yet the versions provided in the PPM and the latest "Libre" versions from Barry are exhibiting this negative behavior with PATHing.

Here to understand and to help

Hello, people.

I've been asked by a member to upload my java install, and on the way to doing so, I started doing some research. It seems that the problem lies with open|libreoffice having trouble recognizing java versions that come after publication of the particular version of open|libreoffice; the problem does not appear to lie with java and only partially with Puppy. The problem may also lie with users that are too eager to use the latest everything! (Ah, human nature!)

After reading how even windows users had problems getting their open|libreoffice to recognize java, for ex. at
https://bugs.freedesktop.org/show_bug.cgi?id=38811
and at
https://bugs.freedesktop.org/show_bug.cgi?id=39659
I did a few experiments on my lupu 5.25-retro-4.

In passing, both coolpup and 01micko did a magnificent job in packaging libreoffice for Puppy. We are probably the only Linux to be able to put libreoffice on whatever drive we please.

So, I have installed LO 3.3.1 (01micko's sfs) and coolpup's ROX-app packaging of LO 3.4.3.
As to java, I have installed jre1.6.0_29, jre1.6.0_31 and jre1.7.0_03, all located at /mnt/home/java.

Now, in conjonction with LO, I have tried to get LO to recognize at least one java in the usual way, by way of Tools-> Options -> java -> Add, and then go to /mnt/home/java/jre* and click on a particular java version. My six attempts ended up wit a failure.

However, by going to /initrd/pup_rw/mnt/home/java/jre1.6.0_29, this java was recognized. The other two were not.

Worthy of note, both LO's recognized time and again jre1.6.0_29 hooked to LO in this way. There is a couple of seconds of waiting, but that' s the only annoyance. A java hooked in this way does not "disappear" as in gcmartin's description.

I explain the failure with /initrd/pup_rw/mnt/home/java/jre1.6.0_31, because it was published later.

The failure with /initrd/pup_rw/mnt/home/java/jre1.7.0_03 is probably due to the fact that it is at this time a development version, and also as far as I can tell, it has a slightly different directory structure that the previous javas. If you do a search on < java 1.7 AND open|libre office >, you will come across numerous reports of LO|OOo being allergic to java 1.7 at this time.

As an aside, reportedly, the new Apache OpenOffice 3.4 will fully recognize java 1.7. Apache OpenOffice 3.4 should be out May 1st (a few days from now).

The problem lies partially with Puppy in that, in Puppy, /mnt/home is actually a variable that shadows /init_save/mnt/home. For example, try the find command to find a unique (as in "only one") file in /mnt/home with "ls" as subsidiary command and find will report it twice.

I hope this sheds some light on the problem.

G'bye, all.

PS @the member who asked: In view of the above, I don't think it is necessary for me to assemble a new java package, since the problem does not lie with any java package that a two-legged Puppy could assemble or has assembled!
