Does anyone know how to connect to an MySQL server so the plugin can store a file on a server and then on another server with the same plugin it would create a file on the MySQL server too. I have no idea where to start.
MySQL cannot be taught in one post, or one fourm for that matter. You (most likely) will not find a tutorial on how to do this relating to bukkit in any way. Here is a tutorial I found after about 5ms of searching: http://www.mysqltutorial.org/ *You might need to serialize the file depending on what type of file you want to save
I actually just started taking a look at MySQL today, so I can see why you are getting lost and confused. Code: Step 1) Understand MySQL via its commands (As the tutorials mostly teach). Step 2) Practice interacting with MySQL through the commands. Step 3) Use java to connect with a test Database, and experiment only using the Java code. Step 4) Use in Production Code.
