I'm trying to recieve messages sent from a server plugin as packets. (Discriminator 109)

Plugin code:

 

Messenger m = getServer().getMessenger();

// setup referee plugin channels
m.registerOutgoingPluginChannel(this, REFEREE_PLUGIN_CHANNEL);
m.registerIncomingPluginChannel(this, REFEREE_PLUGIN_CHANNEL, refChannelListener);

 

 

Handler:

 

public class Handle implements IMessageHandler<GenericMessage, IMessage> {
@Override
public IMessage onMessage(GenericMessage message, MessageContext ctx) {
	System.out.println(message);
	return message;
                // Do stuff with the message.
}
}

 

 

GenericMessage:

 

public class GenericMessage implements IMessage{
String s;
public GenericMessage() {
}
public GenericMessage(String s){
	this.s = s;
}

@Override
public void fromBytes(ByteBuf buf){
	//System.out.println(ByteBufUtils.readTag(buf));
	System.out.println("From Bytes");
	s = ByteBufUtils.readUTF8String(buf);
}
public String getMessage() {
	return s;
}
@Override
public void toBytes(ByteBuf buf) {
	buf.writeBytes(s.getBytes());
}

}

 

 

Mod Init

@EventHandler
    public void init(FMLInitializationEvent event)
    {
    	network = NetworkRegistry.INSTANCE.newSimpleChannel("autoref:referee");
        network.registerMessage(Handle.class, GenericMessage.class, 109, Side.CLIENT);
    }

 

 

Error:

Any ideas?

Well, you haven't shown where you send the message in Bukkit (also, why bukkit? It's dead). Your toBytes and fromBytes in GenericMessage do not match up. You use readUTF8String but not writeUTF8String.

 

Plugin send info:

 

 

Encoding:

public static final String PLUGIN_CHANNEL_ENC = "UTF-8";

Function: (sendPluginMessage refers to void org.bukkit.plugin.messaging.PluginMessageRecipient.sendPluginMessage(Plugin arg0, String arg1, byte[] arg2))

public static void messageReferee(Player ref, String ...parts)
{
	try
	{
		String msg = StringUtils.join(parts, SpectatorListener.DELIMITER);
		ref.sendPluginMessage(AutoReferee.getInstance(), AutoReferee.REFEREE_PLUGIN_CHANNEL,
			msg.getBytes(AutoReferee.PLUGIN_CHANNEL_ENC));
	}
	catch (UnsupportedEncodingException e)
	{ AutoReferee.log("Unsupported encoding: " + AutoReferee.PLUGIN_CHANNEL_ENC); }
}

Function call: (called when match is created)

messageReferees("match", getWorld().getName(), "init");
	loadWorldConfiguration();

	messageReferees("match", getWorld().getName(), "map", getMapName());

 

 

 

I fixed toBytes as well! (Still same error)

 

@Override
public void toBytes(ByteBuf buf) {
                // Converts the message from the outgoing constructor to bytes for sending.
	ByteBufUtils.writeUTF8String(buf, s);
}

 

 

(I didn't create the plugin, btw)
