Basically, I recently removed WXP from my laptop and installed Linux Xubuntu on it. I would like to run my former Java projects.I have some difficulties for installing Java. I have followed instructions of the following web page : http://java.sun.com/j2se/1.4.2/install-linux.html but I've got some issues... I have choosen the RPM installation. when I have typed the following commands on the shell : http://java.sun.com/j2se/1.4.2/install-linux.html ./jre-1_5_0_06-linux-i586-rpm.bin I've got the following errors : inflating: jre-1_5_0_06-linux-i586.rpm error: Failed dependencies: glibc >= 2.1.2-11 is needed by jre-1.5.0_06-fcs.i586 sh-utils >= 2.0-1 is needed by jre-1.5.0_06-fcs.i586 fileutils >= 4.0-8 is needed by jre-1.5.0_06-fcs.i586 gawk >= 3.0.4-1 is needed by jre-1.5.0_06-fcs.i586 textutils >= 2.0-2 is needed by jre-1.5.0_06-fcs.i586 /bin/sh is needed by jre-1.5.0_06-fcs.i586 If someone has got an idea then let me know cheers

Most Linux distributions come with Java installed. To test this, enter the command "which java". This will tell you if (and where) you already have it installed.

If you know it's not installed, or are updating version, sorry, please ignore me [smile].

you're maybe right. it seems to be already installed. i think the problem comes from how configuring mozilla firefox with it...

Do not install Java via .rpm in Ubuntu; Rather, download the .bin (self extract file), and run it with "sudo sh (file).bin" on the directory where you want to install the JDK.

Also, you'll want to create a symbolic link to the new JDK:

cd /usr/bin
unlink java
ln -s /opt/jdk1.6/bin/java java

The command above will create a link to the "java" app in the JDK 1.6 folder, if installed on /opt

To have packages such as build essential packages, you need to enable extra and/or restricted repositories on apt, and use "sudo apt-get install" command. For example, "sudo apt-get install build-essentials" will install several compilers and other essential tools for building and compiling applications on Ubuntu.

Let me know if you have more problems.

I've didn't really get how work the symbolic link.
It seems that Java and Mozilla are installed in the same folder: usr/bin
How should I write commands that set the symbolic link?

In order to integrate Mozilla and Java, look at the guide I suggested on my previous post, here.

To create symbolic links, you use the "ln" command. Type "ln man" on your terminal window, and the manual for this command will appear for you. Do you have any previous experience with Linux? If not, I really suggest you to go through that guide before doing anything else.

I know this website, I have used it to install some application. Nonetheless, the following commands don't work :

sudo apt-get install sun-java5-jre sun-java5-plugin


basically when I type them I've got the following error :


Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package sun-java5-jre

That's because you haven't enabled the extra repositories. Check the link on the same website. A repository is a place where the package manager will look for files, and the standard repositories that come with the distribution do not contain such packages.

Even enabling extra repositories doesn't work. Basically I have chosen to do it by using the terminal, but I've got the following errors :

I'm quite desperate...

You need to make sure that no0 other package management software is running (make sure that Synaptic or something isn't open, for example) and you need to MAKE SURE YOU'RE ROOT.

Also, if you haven't done it, make sure you have the right package name... do an "apt-cache search java" and see what's in the repository.
