Open the About Eclipse dialog (Help -> About Eclipse on Windows, Eclipse -> About Eclipse on OS X)

About Eclipse dialog

Click "Installation Details", choose the Configuration tab, and scroll down to the "java.home" entry. The value is the path name to the JVM used.

In the tab that I have shown in the picture, why does it show `jdk` under the `jre` tab ? Value in home variable `java.home=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9/jre` – Suhail Gupta Mar 13 '14 at 17:10
JDK's include JRE's. And the public source which Eclipse knows how to use. – Thorbjørn Ravn Andersen Mar 13 '14 at 17:32

To see which Java Eclipse itself is using go to Help > About Eclipse click Installation Details and look at the Configuration tab.

When you run Java programs from Eclipse you can select which Java is used. Preferences > Installed JREs lists the JREs (and JDKs) that Eclipse knows about. The Run Configuration for the program shows which Java is used to run the program.

under my _jre_ tab, I see this http://s13.postimg.org/rk1ljg4dj/Screenshot_at_2014_03_13_22_30_19.png It says `JDK` – Suhail Gupta Mar 13 '14 at 17:01
please click the Alternate JRE radio button – T8Z Mar 13 '14 at 17:04
This does not guarantee to tell which JVM Eclipse uses itself. – Thorbjørn Ravn Andersen Mar 13 '14 at 17:05
@ Suhail Gupta -> Some of the jdk include the jre – T8Z Mar 13 '14 at 17:11
@Thorbjørn Ravn Andersen -> Hello, yes this is not guarantee but it can know the jre version so I suggested this. Thank you for your comment. – T8Z Mar 13 '14 at 17:13
