Java instalation - sudo apt-get install sun-java6-jre

[sevi4310]

Hi,
I am trying to install Java.
NO luck.
Did anyone try?
Any advise would be appreciated.

This is a known packaging issue (I did find the actual defect.... not going back to look for it).

Hopefully this will be fixed soon.

I am using openjdk-6-jdk.  This does work pretty well, my biggest problem is that it takes over 300 meg of disk space.

Hope that helps,

Doug

Sun has a 1.4.2 for embedded device. Works, but is a 90 day trial.
http://java.sun.com/javase/downloads/embedded.jsp
--> EABI, glibc2.4, Soft Float

I tried Java from Blackdown People as well. Didn't work.

Are there any other disadvantegs when using openJDK?

There is also a headless version of OpenJDK available (for non-GUI applications):

sudo apt-get install openjdk-6-jre-headless

It's still a beefy-sized package, but a lot smaller than 300MB.  I've only used it to install and run Openfire, but it's been working fine so far for me.

Hi -- Got my ShevaPlug yesterday, and thanks to this post my custom java application is working using the open-jdk runtime.  I was frankly very surprised.. Designed an application in java that communicates with a Morningstar Solar charge controller to receive battery array status, charge rates.  Compiled the java and the protocol library on Gentoo Linux, and moved over the class and jar files.  Now, if I can get heyu running I can real time turn my freezer on and off the grid.   All for under 10 watts of power..

Again, my t hanks.

I installed openjdk-6-jre-headless but my Java program doesn't work. It uses the RXTX library from http://users.frii.com/jarvi/rxtx/ that gives an error. Previously I've ran it successfully on desktop linux computers using Sun java. So I think I need some way to get Sun java installed (since the apt-get method doesn't work). If the problem is at the RXTX-library then it might be harder to fix. I'm wondering if it's ok to manually install a java distribution say directly from java.sun.com? I guess I should try the "embedded" version, damn Sun just makes me to fill a long form to download it. Any help is appreciated.

Only solution I can think of is to download the GNU RXTX library, compile and add it to the OS.  I have used the RXTX library in a java app,
and by-passed the RXTS by the purchase of a MODBUS gateway which allows me to use the internet, and such avoid the hardware
dependency..

I found a version of RXTX from http://rxtx.qbang.org/ToyBox/2.1-7-build1/Linux/glibc-2.3.5/ that I installed (I used arm-softfloat-linux-gnu). However now I get an error message about GLIBC. I wonder if I need to have the exact version the RXTX is compiled for (2.3.5)? I checked that my plug has glibc 2.9. Anyone have any ideas?

Not sure if you're still having the problem, but I installed librxtx-java with apt-get and it's working great with openjdk6.  The only snag was I had to install an updated kernel to get usb-serial support: http://www.openplug.org/plugwiki/index.php/Install_Prebuilt_Kernels_From_sheeva.with-linux.com

Here is an article of someone that installed the "default-jdk", whatever that is.
Have you tried that?

When I try variations on default-jdk, open-6-jdk, openjdk-6-jre-headless, they all fail:

Failed to fetch http://ports.ubuntu.com/pool/main/c/cups/libcups2_1.3.9-17ubuntu3_armel.deb  404 Not Found

I'm using the Installer V1.0 (kernel 2.6.30.2 FWIW).

I am expecting to have to add extra external store to actually download it, but I'd like to get some basic prebuilt JDK 1.6 to start testing, rather than going off and building my own!  My target JVM may well involve Zero and Shark, but that's maybe later!  Baby steps first!

PS. Strangely if I run it with the -d (download only) option and then again without, it seems to install fine:

root@ubuntu:~# java -version
java version "1.6.0_0"
OpenJDK Runtime Environment (IcedTea6 1.4.1) (6b14-1.4.1-0ubuntu10)
OpenJDK Core VM (build 14.0-b08, interpreted mode)

[DamonHD]

FWIW, Xerxes Ranby and Gary Benson have generously given me a little shove towards my Shark/Zero goal, and I have just within the last hour got running a ~3x faster version of the JDK (a private build from Xerxes).  This should be available in Ubuntu "Karmic" soon AFAIK.

So, not optimised quite to the degree that x86 builds are, but getting there.  It's probably 10x slower for a given CPU speed right now, x86 --> ARM (Sun JDK --> fast IcedTea).

Now I'm trying the Sun 'embedded' JRE:

http://java.sun.com/javase/embedded/

It's only a JRE, not a full JDK, and it only has the client (C1) HotSpot to reduce footprint, but it works nicely, maybe about 2x off the performance of the x86 server HotSpot.

Pretty good, so my Java app is up and running, albeit in 'test' mode for now.

If I decide to install one of these then there is a ~$50 licence cost.

I have also experienced the same thing. I tried Rappa’s suggestion and thankfully it worked fine. Maybe you should try it, too. Also, you may find it convenient to add the location of this file to your operating system's path variable, otherwise you will need to explicitly refer to the absolute location of java.

BTW, Xerxes mailed me yesterday to say that he still hopes to have a full 'server' JDK with Zero/Shark by the end of the year, but I may start helping him test some intermediate versions from next week.
