How to send data in real time in Java class library like SDK

Local Setup

We can use JavaScript client exchange data as follows:
socket.onchannelmessage = (channelMessage) => {
console.info(“Received chat message:”, channelMessage);
};

const channelId = “pineapple-pizza-lovers-room”;
var response = await socket.send({ channel_join: {
type: 1, // 1 = room, 2 = Direct Message, 3 = Group
target: channelId,
persistence: false,
hidden: false
} });
console.info(“Successfully joined channel:”, response.channel.id);

const messageAck = await socket.send({ channel_message_send: {
channel_id: response.channel.id,
content: {“message”: “Pineapple doesn’t belong on a pizza!”}
} });
console.info(“Successfully sent chat message:”, messageAck);

This is covered in the documentation on this page but for the sake of completion the equivalent Java code looks like this:

SocketClient socket = client.createWebSocket();

SocketListener listener = new AbstractSocketListener() {
  @Override
  public void onChannelMessage(final ChannelMessage message) {
    System.out.format("Received a message on channel %s", message.getChannelId());
    System.out.format("Message content: %s", message.getContent());
  }
};

socket.connect(session, listener).get();

final string roomName = "pineapple-pizza-lovers-room";
final Channel channel = socket.joinChat(roomName, ChannelType.ROOM).get();
System.out.format("Successfully joined channel: %s", roomName);

final String content = "{\"message\":\"Pineapple doesn’t belong on a pizza!\"}";
ChannelMessageAck sendAck = socket.writeChatMessage(channel.getId(), content);
System.out.format("Successfully sent chat message: %s", sendAck);

I used nakama-java-2.0.3-all.jar, but I didn’t find two methods, channeljoin and channelmessagesend

Ah yes, I see the issue. I’ve fixed the code example above and the main documentation will be redeployed soon! Thanks for noticing it!
