Is it possible to install java on the readynas NV+
I have a simple text based java application that grabs data from a webpage and loads to mysql on the readynas. It would be nice if I could schedule and run it all from the NV+ without the need to have my PC do the java part.
I was able to manage to install Java 6 on the pro. (not sure if the NV+ CPU/memory is able to handle it.)
Anyhow here are the steps...
In your /etc/apt/sources.list add
deb http://us.archive.ubuntu.com/ubuntu dapper main restricted deb http://us.archive.ubuntu.com/ubuntu dapper universe multiverse
then I did;
apt-get update apt-get install sun-java6-jdk
After this the rest of the process will display a dialog that will require you to accept the license agreement. When you do, the rest of the setup will happen on its own.
change temporary in
dpkg-reconfigure debconf
NonInteractive to Readline, once completed change it back

When you're on the command prompt type
javac -version
or
java -version
You should be good to go! 😄
Sorry for delay in the response, just come back from the year end vacation. First of all thanks for the reply.
My NV+ is vanilla out of the box installation so the commands above don't appear on my box...... 😞
How scarey is the process of changing it to handle this? I have plenty experience with linux , but there's alot of data on the NV+ that is not worth losing.
You would need to install the EnableRootSSH add-on in order to gain root access, followed by the APT add-on.
Both add-ons can be found here under the SHELL ACCESS PATCHES: http://www.readynas.com/?page_id=617
You do not need the ToggleSSH add-on (it will disable SSH access if you run it).
As for whether or not it will work, there are others that have also indicated that the CPU on the NV/NV+/Duo is not powerful enough.
Will give it a whirl..... The application I have is so undemanding & I don't care if it takes 10 mins to run even if it only takes 5 secs on my Mac. It's a once per day app, the important thing is it runs by itself...... otherwise I'm going to have to crack out the python or perl books.....

I added the two lines to the end of my sources.list file and then attempted to use your instructions to install java jdk on my PRO and I got the following errors
I have the same problem, but the suggested solution doen´t work. I'm trying this on my ReadyNas NVX Pioneer. My sources.list looks like this:
deb http://www.readynas.com/packages 4.2.13/ deb http://archive.debian.org/debian etch main deb http://us.archive.ubuntu.com/ubuntu dapper main restricted deb http://us.archive.ubuntu.com/ubuntu dapper universe multiverse deb http://archive.canonical.com/ lucid partner
When i run apt-get update the following errors are shown.
[.......] Hit http://www.readynas.com 4.2.13/ Packages Fetched 43.4kB in 1s (29.9kB/s) Reading package lists...

When I try to install java, apt-get install sun-java6-jdk, I get errors about dependicies.
NAS:/# apt-get install sun-java6-jre Reading package lists... Done Building dependency tree... Done You might want to run `apt-get -f install' to correct these: The following packages have unmet dependencies: libsigc++-2.0-dev: Depends: pkg-config but it is not going to be installed Depends: libstdc++-dev sun-java6-jre: Depends: java-common (>= 0.24) but it is not going to be installed Depends: sun-java6-bin (>= 6.20dlj-1ubuntu3) but it is not going to be installed or ia32-sun-java6-bin (>= 6.20dlj-1ubuntu3) but it is not installable E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
Does anyone have an idea to resolve the Public Key errors? Thansk in advance.
Is there another new location for sun-java6-jdk? I made the recommended changes to my /etc/apt/sources.list and get the following error:
NAS_01:~# apt-get install sun-java6-jdk Reading Package Lists... Done Building Dependency Tree... Done Package sun-java6-jdk is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package sun-java6-jdk has no installation candidate

I was wondering if anyone has tried compiling IcedTea for NV+ It is meant to be totally open source so should be possible ? Even if it is using zero interpreter (i.e. no JIT), it would be better than nothing.
It seems that there are instructions for Sparc on Gento Linux which may be useful here. Their method requires someone getting Portage scripts working on Debian Linux first.
Dont know about the NV+ but on my Pro 6, the following worked for me
1. Add "deb http://archive.debian.org/debian-backports etch-backports main non-free" to /etc/apt/sources.list 2. type apt-get update 3. type dpkg-reconfigure debconf Select Option 1 Dialog Select Option 3 Medium 4. type apt-get install sun-java6-jre

Open Source does not neccessarily mean architecture independent. Even if it's written in some high level language like c++ the sourcecode is not neccessarily portable to different architectures by simply compiling it for that architecture. It might be possible to extract the concepts and adapt them to the different environment though. This is likely to be a lifetime task for any normal person. Especially since we are talking about rebuilding a complete virtual abstraction layer between the system and the java bytecode.

Not sure what they are referring to in this case, but keep in mind there are 2 very different sparc architectures around. What is commonly referred to as Sparc nowadays is the late 64 bit sparc based processors like they were used in Sun Workstations. In the Sparc ReadyNAS systems you can find a processor based on the 32 bit Sparc architecture. The Processors in the NAS systems are compact and adapted versions of the processors that Sun built from 1992-1995 (V8 generation). Debian discontinued support for these and even most of the newer Sparc processors that were introduced until 2007 in version 4. (Read: Debian 3 Sarge was the last Debian that had active support for the processor used on the NAS) Most of the packages that come with the Radiator Firmware are custom built by Infrant or Netgear and thus more current than what is available from standard debian repositories.
As far as I know, the Gentoo project does not currently maintain a version for the V8 generation Sparc processors. That means your links are referring to a newer Sparc architecture not compatible with the processor used in our NAS boxes.
