    Post Installing Java JDK + BlueJ

    Hello people. Even though I myself am a SuSE newbie, I had to figure out how to get my BlueJ working from the very first day I booted SUSE simply because I need it for school. In this threat I'm going to explain step by step how to install JDK6 (latest release of Java Development tools) and BlueJ 2.5(Latest release of BlueJ - An open source java Compiler). Here we go.

    In order to develop with Java you need Java developing Tools. It's simply called JDK. In order to get it, you need to download it from After you select the kind of Linux you're using, you need to download the package that ends with ..-rmp.bin. Now mine is called "jdk-6u12-linux-x64-rpm.bin" but since I'm using a 64 bit Linux, Yours should not be. After you download that. Make sure you download it somewhere you could easily direct from the Ternimal(Konsole). Launch the Terminal(konsole).Go under root.
    su or sudo
    After you do that, it'll leave you in your home folder.
    Find the directory where you saved the file.(For example if you were in the home folder and you saved the file onto the desktop, just simply write

    cd Desktop
    You could check the list of items you have under that directory by simply adding

    Just in case, to make sure that the file is there. Once you have it, go into the terminal and write

    sh whatever-the-file-name-is.bin (jdk-6u12-linux-x64-rpm.bin for 64 bit Linux)
    Then it's going to list you the terms and conditions of the package. Simply hold Enter to scroll down all the points of them. Once done It'll ask you to type in "yes" to continue or "no" to cancel.
    Type in yes , simple as it is.
    Once you've done that, It's going to start to unarchive all the files in the bin. Once that's done It's going to start the installation. Give it a minute or two to finish up. At the point where the tools are installed it'll ask you to press enter to finish up. Press "Enter" and give it like 5 seconds. After the terminal announces that the operation was done, you can quit out. We've successfully installed JDK6. Now lets move on to BlueJ


    The newest release is 2.5 which you can find on BlueJ - Download
    make sure you download the bluej-250.jar file.
    Once downloaded, Go into terminal, We're going to do almost the same operation we just did. Go under root. (su or sudo)Find the directory where you saved the bluej-250.jar file. type in:

    java -jar bluej-250.jar

    Once that is done, Give it some time ... It's going to show you a menu kind of thing. Simply browse through your files and find the folder where you want to install it. Browse through your files, and go under /usr/java/jdk6 or something like that. Use that path as your developing tools. Install it. Once installed, it does not add it to your applications menu, so what you have to do is go to the folder you selected while running the installation and run the bluej file.

    There you go. You've just installed JDK6 which is JRE included (JRE - is just the java environment, that will not work if you're trying to configure BlueJ) and BlueJ --> Sun's open source java compiler.

    If any problems post here.
