Java On Ubuntu Linux
« on: September 23, 2006, 04:55 AM »

Hey, got an Ubuntu Linux cd from skima, installed on my Gateway amd laptop, no problem. As a Java Developer and
a Linux freak, I wanted to get up doing my Java stuff, but problems. OK, I will say some of the problems I encountered. The first
was and still is connecting my ubuntu to the internet using my CDMA phone with a usb converter. The second was installing
my Java SE development kits (jdk), this i partially did, partial because up till now I still unable to run my java GUI application
on ubuntu, the default JVM is still been used by the system. However, I have been able to set my classpath and
install Java Enterprise studio and the Gui runs fine.
  My findings, don't want people to make the same mistakes, i made. Infact, I had to reinstall the ubuntu about four times
to get my classpath right. Ok, in ubuntu, unlike other Linux based system, setting your classpath in /etc/profile doesn't
work, you have to set it in a file called /etc/environment, also that will be for system level. When I did that, It worked as root
only, so i had to repeat it in my .bashrc file, after word, javac and other commands were now available to me (my login name), except
tools like policytool that require GUI, even my GUI codes can't run. As I explore more, I will be sharing it also. For people
who are able to install Linux, and don't know what to do after wards, just to do the things you do on your window system
on the Linux box, if you make any mistake and can not fix it, just do re installation and keep trying, it does't bite but
just the time and effort, which you will be happy about later. More to follow.

Hey, guys, mean nobody is interested in catching up in this new fun in linux. To my last post, Some how i was able to get myself started. Since I install my ubuntu, I have been unable to set up my internet connection for some obvious reasons that am still working on, so i had to download the binary version of jdk1.5.0_08 from sun's website. Now, this is what i did to get my sun's jdk and jre running. I created a system link called jdk to my jdk1.5.0_08 directory, all in my /usr/local directory. Next i edited my .bashrc,/etc/profile and /etc/environment files to reflect my new classpath. Now the funny part, I added my jre/bin as the first entry in the /usr/environment path file. Hulala, when i login with my user name, i can actually see my java pointing to the binary version i installed, now i can compile and run any java programme, was also able to install netbean and java studio. Now the problem, as root, my system still point to the ubuntu jvm.

@skima

Hey, am really down with this ubuntu, infact it's bye to windows for now.
Just discovered the support for ubuntu, especially if you have internet access.
All you have to do is connect and use the apt-get install command, your package is
downloaded and install for you without further configuration.
I finally got the chm reader for Linux on ubuntu. I will just add this link for anybody
who wants to explore ubuntu or debian linux system.

@adewaleafolabi
No amarok does not come with ubuntu, but you can download
it from this site, just choose the one that suite your system.
http://amarok.kde.org/wiki/Download
and for installation check http://kubuntu.org/announcements/amarok-1.4.3.php
or if you are connected to the net, just do this,
apt-get install amarok
all the installation and configuration will be done for by the apt tool.
See ya.

Hey guys, just want to invite people with interest in ubuntu or
linux system. To keep a hook on this page. With my ubuntu box, there is
nothing I can't do, with it. Infact the multimedia packages are not more than splendid,
so many to mention are available, window media is just a child play. For hardware suport,
ubuntu supports plug and play for usb devices including mobile phones. On desktop, alot
to choose from, am using flutbox and gnome, hope to install kde an xfce soonest. Is it
development, alot of plugin IDEs are available. What more do want for free. Before i go,
broswers, there are lots, i used mozilla, fire fox and the cool opera.

No prob. You can install both on your laptop. If your laptop has
a single partition, you have to use partition manager 8.0, to
resize your system without affecting your window partition.
Welcome to the world of ubuntu.

Sorry for this late reply. To connect ubuntu to the net using CDMA
require little configuration. If your system has a COM port, you are
lucky, as in you don't have to buy a serial to usb converter.
A lot has been said about this stuff. please try and follow this link.

@Skima
Nice to hear from you. Have been very busy of late myself.
Don't know why you haven't been able to get this stuff running.
May be I have to make a note for you. Try using partition magic, so that
you don't have to mess up your system each time you go stunting.
Thanks.
