Install Oracle Java 7 in [X]Ubuntu 12.04 Precise via PPA

Oracle Java is the alternative to OpenJDK package, but is not longer available in Ubuntu repositories (due to some change in Java License). Oracle Java remains my choice because I find it to work better with some applications (specially java web applets).

If you want to give OpenJDK a try, view here instructions to install it.

“WebUpd8” team provides a PPA with one package that automatically downloads and installs Oracle Java JDK/JRE/Plugin 7 from its official website and installs it on your computer.

Install

Open a terminal window and run:

sudo add-apt-repository ppa:webupd8team/java -y
sudo apt-get update
sudo apt-get install oracle-java7-installer

    Seriously, this saved my life ! I've been struggling all day trying to install Java on Xubuntu, but failed miserably. Until i found this! :)

    This works great, it's easy and simple. For everyone else struggling, use this PPA to install!

    Cheers!

    You can install both. Then you can use the command: "sudo update-alternatives --config java" to choose between them.

    I only use the Oracle version because I need to use a program that doesn't work very well with OpenJDK, otherwise I would only use OpenJDK.

      To add a new user go to: Applications Menu > System > Users and Groups. Probably tomorrow I'll write a new post on the subject, with screenshots explaining the process.

    I find Java really confusing. There is so many different files when I look java up in its directory, and I am not sure what I use for what. Is there a good article to read about Java on linux?

      Java is cross-platform, so once you understand the technology it doesn't matter which system you're run it on. I hope that this getting start guide will make things clearer: http://goo.gl/AjLVc

      At glance there are to main tools:
      javac - to compile source code
      java - to run java programs

      Another tool that's often used by developers is the "javadoc" which produces documentation for the source code.

      Finally there are two more tools for running applications:
      javaw - similar to java but its doesn't have an associated console window. But since you're running Linux you can ignore it, because it's a MS Windows command.
      javaws - used to run web start applications (http://goo.gl/SfuUF)

[FIX] VLC is unable to open the MRL (smb://)

Image
When I tried to open remote video files with VLC via a Samba share I got this error message: Your input can't be opened: VLC is unable to open the MRL 'smb://...' It seems that this problem is related to credentials and can be fixed by entering the credentials for the Samba share in the VLC preferences (Tools > Preferences > Input / Codecs > Access Modules > SMB Input): Note: I only experienced this problem when accessing remote files with PCManFM.
