Java

First, we need to enable Canonical's so-called "partner" repository which includes popular non-free software like Skype, Google Earth or Sun Java. Afterwards we can install all those applications just like you are used to with every other application:

The computing world is always very unpredictable. That must be why there is a small number of people who make large amounts of money from it: they are in the right (unpredictable) place, at the right (unpredictable) time. Who would have ever guessed that Javascript, a simple scripting language initially thought as a simple means to make web pages “cooler”, would become… drum roll… the world’s new CPU?

As many of you have probably discovered the jre available from the Ubuntu repository does not contain a 64-bit java plugin for 64-bit browsers. This means that you have to manually download, extract, and install the 64-bit plugin yourself if you want to be able to view java applets in 64-bit versions of Firefox. While this is not necessarily a cumbersome task it is certainly an inconvenience so I eventually ended up creating a deb package to automate this task. Unfortunately due to Sun's software license I can't redistribute the jre so making the deb package available for download isn't possible. However I have posted the instructions below on how to create your own deb packge which makes for an incredibly easy installation of the 64-bit java plugin.

It is not often that you fail to find half a dozen free software programs to fill a particular niche -browsers, e-mail clients or file managers to name a few; so it was with both surprise and disappointment that I nearly drew a blank in my search for an Electronic Programme Guide (EPG) for GNU/Linux. Yes, Freevo and MythTV have this feature built in, but installing and configuring them just to get your mitts on an EPG looks like overkill. I wanted a simple, stand-alone EPG programme. I got TV-Browser and I got a hell of a lot more than I bargained for. If you install it, you will too.

1) Introduction

This tutorial is meant to help someone install the latest version of the JDK, currently the JDK 6 Update 13. Included in the tutorial is the installation of the JDK itself, as well as installation of the included JRE and Java Web Plugin for Firefox. The instructions may work for other versions of the JDK. Please use your own discretion when deciding whether to use this tutorial with other versions of the JDK. It should be noted that this tutorial also deals with the installation of the new 64 bit Java Web Plugin.

Question:

Hi, I'm trying to install BlueJ so I can do all of my programming in Linux instead of c++ in Linux and Java in Windows.
So far I've used sudo apt-get install openjdk-6-jre-headless
to get my jdk installed, but I'm stumped on installing BlueJ. The installation instructions on their website says to use the command path/to/jdk/bin/java -java bluej-250.jar
My path to jdk seems to be etc/java-6-openjdk I could be wrong if theres another folder somewhere else, but in this folder there is no bin path. So I get a /bin/java not found error, if I leave out the path/to/jdk part it says -java command not recognized.

Vuze (formally Azureus) is not available as a standard deb.
These instructions will get you up and running on 32bit and 64bit ubuntu.

Install Java

If you don't have it you will need java 1.6 or better
to find your current version open a terminal

Code:

java -version

Installing Java for 64-bit

Begin by downloading Java from Sun. Download Here (Linux x64 self-extracting JRE file)

or paste this command into the terminal:

wget -c 'http://www.java.net/download/jdk6/6u12/promoted/b02/binaries/jre-6u12-ea-bin-b02-linux-amd64-08_dec_2008.bin'

Question:

Hello, i used to be able to run JDownloader with no problems in Hardy Heron, but i've recently installed Intrepid and since then im unable to use it.

You useses a wrong Java version. Please use a original Sun Java. Start jDownloader anyway?
Your Java Version:

Question:

Hi all, I need to install java 1.6.0_07 to use in it firefox (for the sake of a particular web page using digital cetificates ... doesn't matter really). Synaptics has versions 05 and 06 only.

Regarding current version 07, I saw at java.com a ".rpm" package and and ".bin" to install in linux, this one with a rather complicated installation procedure. I never used "alien", and I'm afraid of doing a bad install (I really need this for my business). So my question:

Does anyone know an easier procedure to install java07 in ubuntu?
