Installing NetBeans 6.0 on Ubuntu-7.10

I followed the instructions mentioned in this NetBeans Wiki to install NB 6.0 on my ubuntu.

But I feel some more information can be added to this wiki.

For example, when i ran the command "sudo apt-get install sun-java6-jdk", ubuntu complained to me that this package is not found in its repositories.

The problem here is that the package sun-java6-jdk is available in the ubuntu "multiverse" repository which is disabled by default.

In ubuntu, the repositories are defined in the file "/etc/apt/sources.list". Take a backup of this file, in case if you want.

Now open this file and uncomment the lines which define the "universe" and "multiverse" respoitories.

It should look something like this now:

# Line commented out by installer because it failed to verify:
deb http://us.archive.ubuntu.com/ubuntu/ gutsy universe
# Line commented out by installer because it failed to verify:
deb-src http://us.archive.ubuntu.com/ubuntu/ gutsy universe
# Line commented out by installer because it failed to verify:

The job is not done yet.

Run the command "sudo apt-get update" in the terminal to instruct ubuntu to update the package details w.r.t the repositories we enabled just now.

The process might take some time. Wait patiently.

Once the update is done, ensure that the "sun-java6-jdk" package is available in the repositories, by issuing the command "apt-cache search sun-java6-jdk". You might get something like this in the terminal window:

james@kuttima-gifty:/etc/apt$ apt-cache search sun-java6-jdk
sun-java6-bin - Sun Java(TM) Runtime Environment (JRE) 6 (architecture dependent files)
sun-java6-jdk - Sun Java(TM) Development Kit (JDK) 6
sun-java6-jre - Sun Java(TM) Runtime Environment (JRE) 6 (architecture independent files)


Now we are rest assured that our desired packages are available.

Now run the commmand "sudo apt-get install sun-java6-jdk" in the terminal. Depending on your connection speed, this might take quite some time.

Then just follow the instructions to complete the installation.

In the meanwhile, don't forget to download the "netbeans 6.0" installer from netbeans.org. Once you downloaded the installer, you can run it by navigating to the appropriate folder.

In my case, i needed to issue the following command:

sudo sh netbeans-6.0.1-ml-javaee-linux.sh


This will invoke the netbeans installer and just follow the instructions to complete the installation process.

That's it, netbeans will install itself smootly on your machine.

Sharing Windows XP folder with Ubuntu

Since i'm new to ubuntu, all my files were basically residing in windows xp.
As i was working with ubuntu, i thought of relaxing a bit by viewing some photos taken recently. But all of them were sitting inside my xp and i need some way to access it.

Transferring them via usb is an option, but i wanted an even elegant solution. Then i came to know that VirtualBox supports "sharing" folders between "host" and "guest" operating systems.

I read in the VirtualBox manual, that "sharing" folders between "windows" host and "windows" guest is more or less seamless. But "sharing" between "windows" host and "linux" guest need some additional work.

But it's not very tough.

First i needed to configure the shared folder in my VirtualBox. I clicked the menu "Devices->Shared Folders" to configure the sharing. And I choose a folder in my xp machine and gave a share name to that.

Then i opened the terminal in ubuntu and created a directory called share under "mnt" so it looks as "/mnt/share". This required "admin" privileges.

Then i executed the command: sudo mount -t vboxsf myphotos /mnt/share
in the terminal. That's it.

And this how it looked after that in the FileBrowser:
