I know of java.com/verity, but it only tells me the the version number of Java, e.g.

Your Java version: Version 8 Update 25

It does not tell me whether I have OpenJDK or Oracle installed. Is there another online service that does tell this?

  1. Try Java Plugin detector

  2. Also Java tester


  3. Also don't forget the terminal - Run in the terminal:

    java -version

  4. If you are using Firefox type about: Plugins. It will show your Java plugin being used:

  • javatester.org does not work for me, because I don't have the most recent version of Java. For security reasons. – Mads Skjern Feb 8 '15 at 17:11
  • The about:plugins worked well. However, if Oracle is installed, then it does not say Oracle anywhere. But I guess, when it does not say OpenJDK, then it's Oracle. – Mads Skjern Feb 8 '15 at 17:11
  • Regarding java -version in the terminal. The JVM run in the terminal is not necessarily the same as the one used by the browser, and in my case, they are different. – Mads Skjern Feb 8 '15 at 17:12
