-**Q: What do I do now?** +**Q: How do I fix that?**
- +
-A: There are many options. One alternative is to download the Java 16 zip file, unzip in the server folder, edit your bat file to use the java.exe you downloaded. +
- +
-**Q: How do I do that?** +
- +
-1.Download this file: https://github.com/AdoptOpenJDK/openjdk16-binaries/releases/download/jdk-16.0.1%2B9/OpenJDK16U-jre_x64_windows_hotspot_16.0.1_9.zip +
- +
-2. Unzip it inside your server folder. +
- +
-3. You will now have a ''jdk-16.0.1+9-jre'' folder inside your server folder. For example if your server folder is located in ''M:\SERVER'', the java folder will be ''M:\SERVER\jdk-16.0.1+9-jre'' +
- +
-4. Edit the start.bat file you use to start your server, replace java with the full path to the java 16 executable. +
- +
-For example, if your current command to start the server is: +
- +
-''**java** -Xms3G -Xmx3G -jar fabric-server-launch.jar nogui'' +
- +
-Edit it like this: +
- +
-''**%~dp0jdk-16.0.1+9-jre\bin\java.exe** -Xms3G -Xmx3G -jar fabric-server-launch.jar nogui''  +
- +
-(When you run the batch file, ''%~dp0'' is replaced with the path where the batch file starting the server is. The assumption is that the start.bat file is inside the server folder.) +
- +
-Save the file, run it, allow java in the firewall warning if you get one, done. +
- +
-**Q: I don't want to use a java zip file, is there any way I can install java 16?** +
- +
-A: Go here https://adoptopenjdk.net/releases.html?variant=openjdk16&jvmVariant=hotspot and pick your Operating System, pick x64, and download the Java JRE installer file (msi for Windows) +
- +
-See [[player:tutorials:java:windows|Install/Verify Java (Windows)]] +
- +
-**Notes:**  +
- +
-1. The java parameters ''-Xms3G -Xmx3G'' used in the example are not mandatory, they are just part of the example. +
- +
-2. Use the proper fabric API for 1.17, the latest one at the moment of writing this tutorial is https://www.curseforge.com/minecraft/mc-mods/fabric-api/files/3341973 +
