install Java?

[GranPaSmurf]

I am still very much the newbie here.
I am intending to use my Kubuntu 11.10 machine to doctor my Palm Pre cell phone. To do so, I need to install Java(6 is what is listed in the tutorials)
I read the stickies and press releases about cancelation of Java 6 availability, but don't quite understand what I am reading.
Can someone walk me through installing Java 6 on Kubuntu machine? with baby-steps?
Thanks in advance.

A good starting point is the Java.com site itself. There you can download the appropriate version/type for your OS/computer. Pop on over there and download the file you need, then--after reading any install instructions they have over there--if you're still not sure what to do, let us know! We'll get you going.

Hi...

As of late, this can be somewhat of a trick, as Sun Java 6 is no longer offered in Canonical's repositories. However, it's still available but it will require a bit of searching for someone who has it, along with possibly a PPA key. Here is a site that still might have a copy, I forgot which one I used. Be sure to also get both the JRE and JDK components.

When you get it installed, Firefox may not recognize the plugin. If it doesn't, please follow the instructions given by Steve on post #2 here.

Hope this helps...

I'm confused, ardvark. The OP said he needs Java 6--and Java 6 is the current version available on Java.com. So...what am I missing?

Hi DYK...

You're not missing anything. From what I have seen (just now) on Java's site, only RPM's and a self extracting binary are offered. I assumed when I made my last post, that something would have to be compiled and/or a set of complex and hard-to-understand instructions would have to be followed in order to get it installed. I thought the instructions I offered would, perhaps, be more easier for a newer user.

After taking a closer look, the instructions don't seem too difficult, but then again, I've been doing this for awhile. Whichever the OP finds easiest.

Here's my understanding:

First, to develop you'll need the JDK - Java Development Kit - as opposed to just the JRE - Jave Runtime Environment (the JDK includes the JRE). When searching for packages, 'jdk' is generally part of the name, rather than 'java' (in my experience).

Second, Sun Java or now Oracle Java is no longer, or will soon not be, available in major distros' repositories, because of Oracle licensing concerns. But the "Open JDK" is now perfectly good for development purposes (in the past it apparently had some issues). And it does have some support from Oracle as well as from the wider community. (If you come across recommendations for gcj, the GNU Compiler for Java, steer clear: I think that still does have areas of incompatibility.)

Therefore, you need to go to the repositories and install openjdk-6-jdk. (Always prefer the Kubuntu repositories unless there is some great reason to go direct to the original.)

Baby steps:

There are a few directions you can take your baby steps in.

• Do you prefer a GUI installer or a command line installer? I'll assume GUI.
• Muon comes with Kubuntu but it gives me headaches, so even for a baby I will recommend installing Synaptic. It looks a bit uglier but works better.
  • (For example - I can't even find openjdk using Muon, though synaptic and command line tools can.)
  • Launch Muon Software Center from the K menu. Search for 'synaptic' and select and install 'Synaptic Package Manager'
• Now launch Synaptic Package Manager from the K menu.
  • In the search box type jdk or openjdk or even openjdk-6-jdk and scroll to openjdk-6-jdk. Click and select 'mark for installation'. There'll be some dependencies - agree to them.
  • Then click 'Apply' in the toolbar.

Hi DYK...

That's a relief! :-D

I see. I've never installed Java any way OTHER than directly from Java's site, and I figured if the OP grabbed the version from there that's correct for him, we could talk him through installing it if its own instructions weren't clear enough.

Hi DYK...

Likewise, I've never done it any other way than what I described. I'll have to give your method a try sometime and compare the two.

when I open Synaptic Package Manager, I get several error messages:
E: Malformed line 46 in source list /etc/apt/sources.list (dist parse)
E: The list of sources could not be read.
Go to the repository dialog to correct the problem.
E:_cache->open() failed. please report

so I launched Muon Software Center to remove Synaptic Package Manager, to do a re-install. It seems to hang up on 'waiting'

While, as a Windows user, I am more familiar with GUI, I don't mind using command line, if you can step me through. If you do so, would you mind including a word or two about why/what? I am a Newbie, but don't want to be one for long.

Front ends

Both the Synaptic and the Muon are graphical user interfaces for the Debian and that way the Ubuntu package management system. The back end is the apt/dpkg.

The Synaptic is using the GTK libraries (Gnome). The Muon is using the Qt libraries (KDE).

They can't work if the back end is not ok.


Error messages

The /etc/apt/sources.list is (man sources.list):

Package resource list for APT
The package resource list is used to locate archives of the package distribution system in use on the system.

E: Malformed line 46 in source list /etc/apt/sources.list (dist parse)

Something is wrong in the line 46 or near it.

The Muon/Synaptic package manager has a gui to edit the sources.list. Muon > Settings > Configure Software Sources. I'm not sure if the gui can help if the sources.list is malformed.

The sources.list is a text list. You could edit it with a text editor. Start the Kate text editor with the root rights:

kdesudo kate /etc/apt/sources.list

Remember to backup the sources.list before you edit it.

If you can't find the problem, you could post the sources.list to the Kubuntu Forums.


Java

The easiest (an opinion) way to install the OpenJDK is with the command line:

Runtime - needed for executing Java GUI and Webstart programs.

sudo apt-get install openjdk-6-jre

Development - environment for building applications, applets, and components

sudo apt-get install openjdk-6-jdk

If you want to use Java with a browser - icedtea6-plugin for the browser

sudo apt-get install icedtea6-plugin

Hi...

The OP needs Sun's version, as stated in the initial post, "to doctor my Palm Pre cell phone."

I'm not sure OpenJDK can do whatever he/she is needing to do with the phone.

Thanks for the extra training comments.

I opened 'sources.list' in Kate. Went to Line 46.
44. deb http://archive.cononical.com/ lucid partner
45. deb-src http://archive.cononical.com/ lucid partner
46. http://archive.canonical.com/lucid partner
47, deb-src://archive.cononical.com/lucid partner

I did:
sudo apt-get install openjdk-6-jre
in Konsole and found the same error messages.

Thanks Ardvark71,
Me neither. I will just be stepping through a tutorial. Thanks to all for your time with the new guy. BTW, does OP mean 'old person' - is there a hidden camera in my machine I don't know about?

[OneLine]

44. deb http://archive.cononical.com/ lucid partner
45. deb-src http://archive.cononical.com/ lucid partner
46. http://archive.canonical.com/lucid partner
47, deb-src://archive.cononical.com/lucid partner

The source lines should start with the comment mark "#" or "deb" or "deb-src".

Are there twice the partner repositories ?
Lines 46 and 47 are malformed 44 and 45 ?
