For this example, we will host and share a Minecraft server with a contact.

  1. Create a dedicated folder on your machine for your Minecraft server. In this example, we will name the folder MC Server.

  2. Download the official Minecraft server (server.jar) from the Minecraft website and move it to the MC Server folder.

  3. Ensure Java is installed before running the server.jar file. On Windows, double-click the server.jar file. On Linux and macOS, run the following command in the directory that contains the server.jar file: java -Xmx4G -Xms4G -jar server.jar nogui

  4. After running the server.jar file, the MC Server folder will contain additional files. You need to modify two of these files: a. eula.txt: Set eula=true in this file after reading and agreeing to the EULA. b. server.properties: Use this file to configure your Minecraft server as required. Check the following property:

    • Set the server-port value. You can usually leave this at the default value of 25565 provided that it’s not already in use.

  5. Save the changes and restart the server using the same method as in Step 3. The server is ready when the console displays the Done message.

  6. Add a custom service to Jami. Ensure the Local port field matches the value you set for server-port. As with shared directories and websites, you can control access to the service. After configuring the service, select the Save button.

    An example configuration for sharing the custom Minecraft server on Jami.

  7. Before inviting others, verify that you can connect to the Minecraft server yourself. Inside Minecraft, navigate to Multiplayer → Direct Connection and enter server-ip-address:server-port in the Server Address field, then select the Connect button. If everything is working correctly, you should successfully join the server and see the following message in the server log: USERNAME joined the game.

  8. Once you’ve confirmed the server is working correctly, invite your contacts to join.

    • Your contact opens your shared services list and selects your shared Minecraft server.

    • The server address is copied to their clipboard automatically.

    • They paste the address into the Server Address field in Minecraft and select Join Server.
