You might also want to install the full Java Development Kit, which can be done so:

sudo apt-get openjdk-6-jdk

One thing this gets you is the jar command for creating/modifying .jar files.

Hi,
I am using Xubuntu 10.10 and Google Chrome as browser. I installed the version 20 from Ubuntu Software Center, IcedTea, OpenJDK runtime and web start. It seems even today the version I got is still 20. However some companies in Singapore had upgraded their website and you need version 26. If the Ubuntu Software Center has not updated their Java package how can I upgrade to version 26?

The above (sudo apt-get install sun-java6-jre) does not work for me:
# sudo apt-get install sun-java6-jre
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package sun-java6-jre 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-jre’ has no installation candidate

OTOH, I would appreciate a hint on WHICH of the JRE’s (listed e.g. when you do “apt-cache search jre”) to install (differences) ?

The standard-jre would download 50MB, the gcj-jre only 20MB.

I don’t have a GUI on my Ubuntu server, but wanted a Minecraft server running. To install Java, I opened up a Screen and entered

sudo apt-get install sun-java6-jre

In the process, it popped up a “dialog” asking me to accept the license, but there was no way to respond to the dialog -- probably due to the license being too many words to fit in the screen.

I opened up another Screen, and found the apt-get process, then followed it’s children until I found a whiptail process that was responsible for presenting the dialog. I killed that process.

The install then popped up another, smaller, dialog (something to the effect of ‘you must accept the license…’) that I COULD respond to, and the install succeeded after that.

I’m at the point where I have to agree to the DLJ terms, and there is no yes for me to select. There is an OK at the bottom, except I can’t click on it. Can anyone help me with this.

RE Chuck Ishman
This command worked , it was slow d/l from wifi

sudo apt-get install openjdk-6-jre-headless sun-java6-plugin sun-java6-fonts

Good posting. I managed to get the plugin to work, but from what’s in this thread, I’ll go back and check to make sure that the rest of the packages installed correctly.

Regarding the plugin --- remove the icedtea plugin and the Sun Java won will then appear --- they can’t be there concurrently, even if you have disabled the icedtea. At least that’s how it worked for me…

Don’t forget the apt-get update after adding the new repository.

I try to install these from .deb packages, but can’t do this because it has recursive dependences and I just add repository in sources.list, then update list in Synaptic, search needed packages by “sun-java6″, check for install sun-java6-jre, sun-java6-plugin and sun-java6-fonts - now all OK.
Thanks for guide

OMG!!! I love it when the code works! I also ran into the same problem with “Package sun-java6-jre is not available but is referred to by another package.” The post by oOze corrected my problem. Thanks to all who posted the code that worked for them. It seems to do the trick. I would suggest this as an update:

sudo apt-get install openjdk-6-jre-headless sun-java6-plugin sun-java6-fonts
