Detecting the JRE Version

If OnDemand is not working properly, ensure that the user is running a version of the Java Runtime Environment (JRE) that is supported by OnDemand; see Client Components for system requirements. In addition, make sure the user has enabled Java in the browser; see Enabling Java in the Browser.

To detect the JRE version running on a client computer

  • Internet Explorer for Windows: Open the browser’s Java Console to view information about your JRE; see Viewing the Java Console.

  • Browsers for macOS: In the Applications folder, open the Utilities folder, and then open the Java folder. Run the Java Plugin Settings program, and then click About in the menu to see information about the version you are running.

Some versions of Windows may not include a JRE; in this case, you see an error message (jview.exe must exist in \path or you need to set JAVA_HOME). If you see this message, but you know that you have a JRE on your Windows computer, set the path to the JRE directory as JAVA_HOME in the Environment Variables ; see Windows Help for information. Otherwise, you must either install a JRE on your Windows computer or use a different computer.
