Coral Notes


Mac OS X Users

  • Ensure that Java 6 is up to date on your computer.
  • Mountain Lion or Lion users should use Software Update or the App Store to download the newest version.  Snow Leopard users may need to download from here: http://support.apple.com/kb/DL1573.
  • Java Web Start may not properly launch Coral with Java 6. If you have Java 7 installed, and you get a "Starting Coral" box that won't go away, you may need an assitance application.
  • Download the Coral - Purdue assistance application.
  • Unzip the CoralPurdue.zip program and run the Coral - Purdue application.
  • You may move the Coral - Purdue application to your Applications folder.


  • Coral requires that Java be installed on your computer. Java may be downloaded from the Sun/Oracle Java SE Download website.
  • You must now use your career account username and password. Your old Coral password will no longer work.
  • To access Coral from off campus, you must use the Purdue VPN.
  • Coral Startup Instructions
  • If you are having trouble running Coral on a Sunray:
    • Run javaws from the command line.
    • Go to the Edit menu and select Preferences.
    • Go to the Java tab and click on the View button in the Java Application Runtime Settings.
    • Click on the Find button and navigate to /opt/java and click Next. Select the item in the list with "current" in the path, and click Next.
    • Click OK.
    • Click OK.
    • Go to the File menu and select Exit
    • Next, you need to configure the proper Java Web Start that Firefox uses.
    • Click on Start Coral above.
    • A dialog box asking you how to open the file will appear. Make sure "Open with" is selected, and click the drop down box next to it.
    • Click on Other.
    • Navigate to /opt/java/current/bin/javaws, and click the Open button.
    • Click OK.
    • You should only need to do this once.
