Puppy Linux Discussion Forum

I'm working on a project which involves remastering Puppy with a few extra toys. One of which is Java. I used the jre.1.6.22 pet install which works perfectly in my running version.

Then I tried to remaster - all other things I added (most under /opt directory) were included. Java was omitted. I followed the links to java from /opt/java --> /mnt/home/java --> /java

Any reason why the Java PET installs java in such a unique way? And how does one include directories under / for a remaster?

I'm going to install java manually using the jre bin provided by Oracle which I'm pretty sure will solve my troubles, but if I could learn more about the remaster process then I could benefit from the ease of PET installed Java.

Hello,

It is a bit later reply on your post on the forum regarding java and remaster.

The reason why Java on the repos installs to mnt/home is that it then takes up no place in the personal savefiles. So if you have multi frugal installs on your hd as many people (esp. developers) have, then you can use one Java installation for all puppies and save that 100 MB in each savefile.

There are other big packages which also use this approach (e.g. open office package).

This is exactly the reason, why it is not included in the remasterprocess, because only files which are installed under / are remastered (and there are exceptions in the /root and in the /etc directory which you have to handle manually).

It is possible to copy the files under /mnt/home back in a location somewhere in / tree (maybe /usr/local/java ... but then you have also to adapt all the symlinks etc. Thats not easy and very errorprone.

I had a similar problem, because I wanted to include Java on a distributed live CD. There you want to have java working effectivly with 1.boot so shifting java to /mnt/home was not a good option.

I have mad a pet from java which is stored traditionally in the savefile.
you could download (prop. you dont need anymore, and there is also new Java 1.6.23 released) from www.mydrive.ch (username: download@sagelive, pwd: mathematics)

EDIT: I removed Java from mydrive (ran out of space), and it is included per default in the later Sage Live Pupplets. USe this downloadlink
http://sage.math.washington.edu/home/emil/sagelive/jre_1.6.0_22.pet

Experience also shows that this is interesting for people who want to remaster something with Java working out of the box.

Ok! I understand the reasoning behind it. I worked around it by manually installing Java from the Oracle Linux binary file in the /opt directory and linking Java to /usr/local/bin/java.

Then it was included in the remastering process.

Best regards and thanks for the reply.

1. I went to Oracle's website and found the JAVA JRE 1.6 SELF-EXTRACTING file for LINUX. http://java.com/en/download/manual.jsp

2. I downloaded it into the /opt directory in my Puppy system.

3. I opened a terminal in puppy and navigated to that directory:
