I want to use a SocketChannel and to have a timeout for its read/write methods. I've tried to set a timeout for the Socket that owns my SocketChannel like this: 

channel.socket().setSoTimeout(TIMEOUT);

but that doesn't work. Is there any other solution?

According to this article, SocketChannel will not timeout for its read operation but you can get this effect from reading from the channel in another way.

SocketChannel socketChannel;
socketChannel.socket().setSocketTimeout(500);
InputStream inStream = socketChannel.socket().getInputStream();
ReadableByteChannel wrappedChannel = Channels.newChannel(inStream);

reading from the wrappedChannel will timeout according to the socketTimeOut you have set.
