BlueJ Installation

These are the instructions for the generic BlueJ installer (the installer "for other operating systems"). This installer can be used on most Unix-like operating systems as well as Mac OS X and Windows. However, it is generally preferable to use the "native" installer when available.

Installation Procedure

  1. Download the installer, making sure to keep track of where it is in the filesystem.
  2. Start your Command Prompt or Terminal application. You will complete the installation by typing some commands into this application. (For Windows users, see these instructions for how to start the Command Prompt).
  3. Run the following command:

    java -jar <path-to-bluej-installer>

    ... replacing <path-to-bluej-installer> with the correct path to the installer .jar file that you downloaded.

    If you receive a "command not found" or similar error, you may need to specify the full path to the Java executable. For example:

    "C:\Program Files\Java\jdk1.7.0_65\bin\java.exe" -jar "C:\Users\Sarah\Downloads\bluej-311.jar"

    (this example is for Windows; other operating system paths normally use '/' as a path separator!).

  4. The installer should start and present a window where you can specify both the path to the JDK (make sure it is correct!) and where you want BlueJ to be installed. It is usually best to install BlueJ somewhere under your home folder. Take note of the path as you will need it to run BlueJ later.

Running BlueJ

To run BlueJ:

  • On Windows:

    1. Start the Command Prompt application.
    2. Change into the directory where you installed BlueJ:

      cd <path-to-bluej-installation>

      ... replacing <path-to-bluej-installation> with the path you chose to install BlueJ to.

    3. Start the BlueJ batch file:
      bluej.bat
  • On other operating systems:

    1. Start the Terminal application.
    2. Change into the directory where you installed BlueJ:

      cd <path-to-bluej-installation>

      ... replacing <path-to-bluej-installation> with the path you chose to install BlueJ to.

    3. Start the BlueJ shell script file:
      ./bluej
