Now that I've updated those two registry values, my program runs flawlessly, with no more hiccups or complaints about a missing Java Runtime Environment stemming from the registry. This is the official solution for setting the Java environment from www.
We need to make a distinction between the two environment variables that are discussed here interchangeably. The other is the Path variable. The compiler is aware of its own location.
The variable is meant for other software to more easily locate the compiler. This variable is typically used by IDE software in order to compile and build applications from Java source code. So for instance, if you are not using any IDE software, and you just want to be able to compile from the CMD, independent of your current working directory, then what you want is to set the Path variable correctly.
However, if you are using some IDE software, then you have to look at the documentation first of all. If your problem relates to running Java applications, then you want to check your Path variable. Path variable is used universally across all operating systems. Because it is defined by the system, and because it's the default variable that's used for locating the JRE, there is almost never any problem running Java applications.
Especially not on Windows where the software installers usually set everything up for you. Any recent version of an IDE software should be able to pick that up and use it. Symbolic links may provide yet another way to reference the JDK search path by piggybacking one of the existing environment variables.
This directory contains symbolic links to the java. As long as you use the installer package to set it up. There may be differences on your Windows installation however. If you ever find that your Java JDK configuration is using the wrong version of the compiler, or it appears to be working by magic, without being explicitly defined so without casting the spell , then you may have a symlink somewhere in your environment variables.
So you may want to check for symlink. Use the search feature to make sure your latest Java installation is listed; then make sure it is the one that is checked. While adding your Java directory to your PATH variable, you might want to put it right at the beginning of it. After checking, I've found java. Run Eclipse as Administrator. After hours of work around most of the solutions here, the problem was solved for me just by installing bit JDK.
This also means that it is better to install Java manually, without an installer, so you are able to toy with it. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

God forbid there was an installer that did this step for you : I just switched from the Enterprise version to the Community version and I was convinced I downloaded the wrong thing because it was one-click on the Enterprise version :p — John Humphreys.
Sometimes, the system varible changes does not take effect until you restart the windows. A quicker method is to hit Start, then start typing environment variables — Casebash. JDK is in a separate directory unless you want to do some crazy hack — ericn. Show 4 more comments. Add a comment.

If you're using the installer, you don't need to do this. If the path contains spaces, use the shortened path name. You'll need to close and re-open any command windows that were open before you made these changes, as there's no way to reload environment variables from an active command prompt.
If the changes don't take effect after reopening the command window, restart Windows. Restart Command Prompt to reload the environment variables then use the following command to check the it's been added correctly. Confluence 7. Unable to load. Cloud Data Center and Server 7.
