Solution 1

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.

Solution 2

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.

Solution 3

Please see the following figure.

click on Run from menu bar ->select Run Configuration

Select JRE on tab

This does not guarantee to tell which JVM Eclipse uses itself.

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 -> Some of the jdk include the jre

@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.

JDK's include JRE's. And the public source which Eclipse knows how to use.
