Java

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. There seems to be a problem with my java version, although everything else(java-related) works well. I get this message when trying to run JDownloader:

You useses a wrong Java version. Please use a original Sun Java. Start jDownloader anyway?
Your Java Version:
Runtime Name
icedtea6 1.3.1 (6b12-0ubuntu6) runtime environment
Runtime Version
1.6.0_0-b12

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?

JODE (Java Optimize and Decompile Environment) seems to be the best Java decompiler available. But the installation of JODE and JodeEclipse is far from straightforward:

• NB: The JODE Makefile created a wrong executable that I needed to modify.
• NB: The JodeEclipse plugin you get from the update server said at JodeEclipse website doesn't work (at least it didn't for me with Eclipse 3.4).

This post is used to install the version of frostwire from frostwire's server, instead of using the Ubuntu version.

This tutorial installs java6 in your system. You must use Java to have this work. IcedTea can be used, but I have had bugs with it, and in the latest version it doesn't seem to work with me at all.

Java5 does work. Just replace "/usr/lib/jvm/java-6-sun/jre/bin/java" with "/usr/lib/jvm/java-5-sun/jre/bin/java"

This guide is intended to help users install and configure "R", a great, free alternative to SPSS. The instructions that I outline here are tailored to Ubuntu 8.04 (Hardy Heron), but can be alternated to fit any Linux distribution. I also have these instructions available on my blog located here.

What is "R"?
This is right from the R homepage:

OSCON: Exclusive Canonical has been in talks with Sun Microsystems and SpringSource to support one of their open source Java application server stacks in the Ubuntu core, to increase Ubuntu's enterprise adoption.

Canonical told The Reg that it is in the process of selecting which open source Java Enterprise Edition (Java EE) framework to make available in the main part of its popular Linux distro. Sun's streamlined GlassFish 3.0 and the modular Application Platform are contenders.

Canonical's Ubuntu server engineering manager Rick Clark called it: "Very, very important to us to get a full Java stack out of the box."
