Java archive downloads 8

Java Runtime Environment (JRE) Installation. We strongly recommend that you install Java version 1.8 (also known as Java 8), which can be downloaded from the Oracle web site. Jim will not run with Java versions earlier than 1.8.0. If you use a Java version later than 1.8.0, you may experience problems with the program crashing when you try to start the 3-D display.

Note: if your institution has a purchased floating (network) license for Jim , then please note that you need to install Java version no later than 1.8.0_192. If you install a version of Java 8 later than this, you will not be able to connect to the license server to obtain a license. You can access archived versions of Java 8 here, or search on "Java Archive Downloads Java SE 8 Oracle".

Please follow the download and installation instructions on the Oracle web site. You should, if possible, accept the default installation location.

If you wish to do some Java Programming

If you want to write your own Java programs, perhaps to do some image analysis using the imaging A.P.I. supplied with Jim, then you'll need to install the Java Development Kit (JDK) instead of the JRE. Please go to the Oracle web site, and be sure to download JDK 1.8.0.

License Request. The easiest way to obtain the details needed to send for a license is to try starting Jim. To start Jim, go to the Start button, then select Programs (All Programs on Windows XP, Vista and Windows 7; All Apps on Windows 10), program group Jim8, then the Jim8 menu item. If you have not yet received a license file, you will see a pop-up error dialog like the one shown below.

You will see a line that says something like either:

• This computer's Host ID is: "000123456789"
  Please send this string of digits/letters to .
• This computer's hostids are: "000123456789" "000F1E2D3C4B5"
  If this happens, you have more than one ethernet adapter. Please follow the instructions in the error message to decide which of these to send to .

Note: this is not an automated service, and there will be a delay before you receive your license file.

Please be careful when copying the hostid: if you send the incorrect hostid, Jim will not work. Each hostid is 12 characters long, and consists of the digits 0..9 and the letters A..F.

If in doubt, you can always send us full details about your network adapters by doing the following.

• Go to the Start button, and select All Programs, Accessories, Command Prompt (as seen below, using Windows XP).

  

• When the DOS command prompt window comes up, type in the command:
  This command will create a file called in the folder.
• e-mail the file ip.txt to . We will then be able to choose the appropriate MAC address for your PC.

Note: this is not an automated service, and there will be a delay before you receive your license file.

If you believe that you have received and correctly installed your license file, then you can get Jim to print out more detailed messages about why licensing has failed. Press the button. This will pop up a further dialog containing detailed license debugging messages. You can use these to diagnose the problem, or e-mail the messages shown in this window to , to help us to diagnose the problem.

If you have purchased network (floating) licenses, you can set up the connection to your license server by clicking on the . See the instructions for setting up a connection to a license server.
