Introduction
There are various vendors developing an own version of Java, e.g. Sun, IBM, Blackdown, etc. For TV-Browser we are only able to support the Sun Java-environment. Due to lack of time, we are unable to support the other Java implementations.
Some Linux distributions do not have Sun Java, but offer one of the free alternatives (read about reasons for this in the article by Richard Stallman). These alternatives need to be replaced to make sure TV-Browser is running properly.
JRE or JDK
A short explanation: JRE is short for Java Runtime Environment. It is sufficient to start all kinds of Java programs. The JRE would be adequate for an end-user. For those who would like to try and develop own Java applications may install the JDK (Java Development Kit). Additionally to JRE, JDK also offers developer tools. Basically, it does not matter what you decide for. TV-Browser is running with both versions.
Windows
Simply download the newest version from http://java.com and install it.
For those who encounter difficulties there, please have a look at this manual. Step by step, it leads you through the installation of Java:
http://uckan.info/texte/java-installationsanleitung/
Mac OS X
Mac OS X comes with Java. No further steps are necessary.
Unfortunately, Java 1.4, which comes with Mac OS X, has a few problems with our dialogues. To fix this problem, you may install Java 1.5.
To do so, take the following steps:
- Download and install Java 1.5 release 3
- In /Applications/Utilities/Java/J2SE 5.0/Java Preferences go to "Java Application Runtime-Settings" and, using your mouse, drag the J2SE 5.0 version above the 1.4.2 version.
Debian
On Debian systems, Blackdown Java is installed by default. Unfortunately, it is not absolutely compatible to Sun Java, which makes it necessary to install Sun Java.
See also http://www.debian.org/doc/manuals/debian-java-faq/ch11.html#s11.2
Fedora
See http://home.gagme.com/greg/linux/fc4-tips.php#java
Gentoo
See http://www.gentoo.org/doc/de/java.xml
As described in step 2 in the manual, there are various Java versions you may choose from. We recommend installing the JRE or JDK offered by Sun, as most developers of Java programs use this Java. You will therefore experience hardly any problems.
OpenSuse
See http://www.opensuse.org/Java
Suse
In Yast, go to Software>Software install or delete. Then search for Java and install the java-1_5_0-sun-packages.
(K)Ubuntu
(K)Ubuntu offers only GCJ, which is the free Java-environment. Unfortunately, it is not yet hundred per cent compatible to the Sun VM and therefore can not be used with TV-Browser.
Please install the Sun VM, taking the following steps:
- Add this source:
deb http://ubuntu.tower-net.de/ubuntu/ breezy java
- Install package "sun-j2re1.5"
- In a terminal, enter:
sudo update-alternatives --config java
- Now select the SUN VM in the list.
The Sun VM is now installed.
