Simple TCP Client - Spring Integration ( Not connecting)

[pkbhavani]

I am trying to simulate following simple tcp client which connect to a socket and reads the data when available and prints.

public class TestAdapter {
	public static void main(String[] args) throws IOException {
		Socket socket = null;
		PrintWriter out = null;
		BufferedReader in = null;

		try {
			socket = new Socket("localhost ", 11111);
			boolean state = socket.isConnected();
			if( state) 
				System.out.println("Successfuly connected ");
			in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
		} catch (UnknownHostException e) {
			System.err.println("Don't know about host: localhost.");
			System.exit(1);
		} catch (IOException e) {
			System.err.println("Couldn't get I/O for " + "the connection to: localhost.");
			System.exit(1);
		}

		String userInput;
	
		while ((userInput = in.readLine()) != null) {
			System.out.println("echo: " + userInput);
		}

		out.close();
		in.close();
		socket.close();
	}

}

With the following configuration, test method on PrintService is not getting invoked when there is some bytes available.
Can anyone help me correct these settings if anything wrong?

<int:channel id="inputChannel"/> 
<ip:tcp-inbound-channel-adapter id="tcpInboundAdapter" 
	                               	channel="inputChannel" 
	                               	connection-factory="client" 
	                           	client-mode="true"  /> 
<ip:tcp-connection-factory id="client" 
				type="client"
				host="localhost"
				port="11111" 
				single-use="false"
				using-nio="true"
				using-direct-buffers="false"
				pool-size="2"
				so-keep-alive="true"
				so-timeout="0"/>
<int:service-activator id="activator"
               		   input-channel="inputChannel"
	   		   ref="printService"
	   		   method="test"/>
<bean id="printService" class="com.springintegration.print.PrintService" />

public class PrintService {
	public void test(byte[] bytes) {
		System.out.println("Received:" + new String(bytes) );
	}
}

from the debug log, connection seems to be established, but the service activator is not invoking test method on PrintService
