    I developed my plugin, fixed all error, then it compiled. so, I installed it for testing, and it broke the server. But I can't figure out how to get the error on here. I can't copy and paste it from the command line, and I can't find a file that it writes to. If somebody could tell me how to do that, then I could get it on here, and it could be fixed. Or I could just send you the source file, and you will probably get the same error. It won't finish loading the server basically. I need this up for tomorrow.

    Delete your server.log so it's empty. Now run your server and make the error appear in the console. Then the error should be in your server.log

    Are you using Eclipse to code the plugins? Just because there isn't a logic or syntax error doesn't mean that something in the code can't go wrong. You should post your code on here so people can look at it.

    Yes, I'm using Eclipse. Here's my code:


    import java.util.logging.Logger;

    import org.bukkit.command.Command;
    import org.bukkit.command.CommandSender;
    import org.bukkit.configuration.file.FileConfiguration;
    import org.bukkit.entity.Player;
    import org.bukkit.plugin.java.JavaPlugin;


    public class plugin extends JavaPlugin {
    protected static FileConfiguration CONFIG;
    Logger log = Logger.getLogger("Minecraft");

    public void onEnable() {
    CONFIG = getConfig();
    CONFIG.set("your boolean property", true);
    CONFIG.set("your string property, "yes"");
    CONFIG.set("your int property", 22);
    boolean bProp = CONFIG.getBoolean("your boolean property", false);
    String sProp = CONFIG.getString("your string property", "no");
    int iProp = CONFIG.getInt("your int property", 0);
    log.info("Your plugin has been enabled.");
    }
    public void onDisable() {
    log.info("Your plugin has been disabled.");
    }
    }

    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
    if(cmd.getName().equalsIgnoreCase("ignite")){
    Player s = (Player)sender;
    Player target = s.getWorld().getPlayer(args[0]);
    target.setFireTicks(100);
    return true;
    }
    return false;
    }

    and here's my error:

    java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Map

    probably means:

    Player s = (Player)sender;

    is most likely wrong. CommandSender is not same as Player.

    there, happy?

    so, what your saying, is I have something wrong with the Player s = (Player)sender; line?

    Yes there is something wrong with your casting.

    A Player is a CommandSender, but a CommandSender is not always a player. You should check to make sure it's a Player before casting by doing if(sender instanceof Player). However, that is not your problem here. Your problem is in your plugin.yml file.

    3. if (cmd.getName().equalsIgnoreCase("portal") {
    4. if (sender instanceOf Player) {

    there are three {'s!
    is this my error?

    That is correct, except instanceOf should be instanceof
    Your error is here:
    CONFIG.set("your string property, "yes"");

    Should be

    CONFIG.set("your string property
    ", "yes");
