# Java requirements

Before you start, follow these steps to ensure that your Java environment is suitable:

1. Verify that your computer has a supported Java version installed:

**Supported Java Versions**

| Vendor                                                                                                                                                                                                                                           | Versions |
| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -------- |
| OpenJDK, including OpenJDK-based distributions:- AdoptOpenJDK/Eclipse Temurin

- Amazon Corretto

- Azul Zulu

- Red Hat OpenJDK	ForgeRock tests most extensively with AdoptOpenJDK/Eclipse Temurin. ForgeRock recommends using the HotSpot JVM. | 11       |
| Oracle Java                                                                                                                                                                                                                                      | 11       |

1. Read the [pre-installation requirements](../release-notes/before-you-install.html).

2. Set the `JAVA_HOME` environment variable:

   > **Collapse: Set JAVA_HOME on Windows**
   >
   > 1. Locate the JRE installation directory (typically, `C:\Program Files\Java\`).
   >
   > 2. Click Start > Control Panel > System and Security > System.
   >
   > 3. Click Advanced System Settings.
   >
   > 4. Click Environment Variables.
   >
   > 5. Under System Variables, click New.
   >
   > 6. Enter the Variable name (`JAVA_HOME`) and set the Variable value to the JRE installation directory; for example `C:\Program Files\Java\jre8`.
   >
   > 7. Click OK.

   > **Collapse: Set JAVA_HOME on Linux**
   >
   > 1. Open the user shell configuration file found in your home directory.
   >
   > 2. Add the `JAVA_HOME` variable to the user shell configuration file, setting the value to `/usr`. In Bash, this would appear as `export JAVA_HOME="/usr"`.
