Those tools listed above can create a very small runtime custom-fit to your particular app. Read the white paper Java Is Still Free, authored by key members of the Java community.ĭesktop apps are now expected to bundle their own Java runtime.Read this white paper by Oracle of 2018-03, Java Client Roadmap Update.Understand clearly the nature of the OpenJDK project, as explained in Wikipedia.The only folks consciously installing a JDK will be developers & server-side sysadmins. Java-based apps are expected to bundle their own Java implementation. Java Applets in a browser and Java Web Start app delivery are both being phased out, leaving the end-user with no need for a JRE. Oracle no longer intends for end-users to be installing a JRE or a JDK. javapath Īs you see javapath (that is in PATH environment variable) points to javapath_target_3015921.The Answer by Stephen C is correct, and important. In path C:\Program Files (x86)\Common Files\Oracle\Java: > dir "C:\Program Files (x86)\Common Files\Oracle\Java" On Windows machine, there are also two another differences between JDK 8 and JDK 11.Ī standalone JRE alongside JDK as you can see: > dir /b "C:\Program Files\Java" Same snapshots on Windows machine: > dir /b "C:\Program Files\Java\jdk-11.0.1" Same snapshot about Oracle JDK 8 (See jre folder specially): # ls /usr/java/jdk1.8.0_191-amd64/ĬOPYRIGHT LICENSE THIRDPARTYLICENSEREADME-JAVAFX.txt As you can see there is no jre folder: # ls /usr/java/jdk-11.0.1/īin conf include jmods legal lib README.html release This is a snapshot of installation path on CentOS 7. But I saw an unexpected thing! Where is JRE? _windows-圆4_bin.exe (first on a Linux machine and second on a Windows machine). I downloaded and installed Oracle JDK 11 from its official site. I was expecting JRE to be installed with JDK.ĭo final users of our apps need to install JDK? But where is JRE 11?!Īlso, JDK 11 doesn't include a JRE.
You can find JRE 8, JRE 9 and JRE 10 on Oracle's official website (click on each).
