How to catch tcp client request message in wso2 esb proxy service - tcp

Question

Im new comer to Wso2 esb. Now I'm working with tcp protocol and proxy service. I have some question. I send some message to the proxy service through tcp protocol. I need get this message to the property mediator in the proxy service. But my way not catch that value in the property mediator.
Here is my proxy service
<?xml version="1.0" encoding="UTF-8"?>
<proxy name="TCPProxyService" startOnLoad="true" transports="tcp" xmlns="http://ws.apache.org/ns/synapse">
<target>
<inSequence>
<property description="" expression="get-property('message')" name="MessageValue" scope="default" type="STRING"/>
<log description="" level="custom">
<property name="property_name" value="============================="/>
<property expression="get-property('MessageValue')" name="inputValue"/>
</log>
<sequence key="in-sequence"/>
<log/>
<respond/>
</inSequence>
<outSequence/>
<faultSequence/>
</target>
<parameter name="transport.tcp.responseClient">true</parameter>
<parameter name="transport.tcp.inputType">string</parameter>
<parameter name="transport.tcp.recordDelimiter">|</parameter>
<parameter name="transport.tcp.contentType">text/plain</parameter>
<parameter name="transport.tcp.port">6789</parameter>
<parameter name="transport.tcp.recordDelimiterType">character</parameter>
</proxy>
Here is my Java client for send tcp request
import java.io.*;
import java.net.*;
class TCPClient {
public static void main(String argv[]) throws Exception {
String delimiter = "|";
int modifiedSentence;
Socket clientSocket = new Socket("localhost", 6789);
DataOutputStream outToServer = new
DataOutputStream(clientSocket.getOutputStream());
BufferedReader inFromServer = new BufferedReader(new
InputStreamReader(clientSocket.getInputStream()));
String message = "Pietoo,Klaas,also" + delimiter;
outToServer.writeBytes(message);
outToServer.flush();
while ((modifiedSentence = inFromServer.read()) > -1){
System.out.print((char)modifiedSentence);
}
clientSocket.close();
}
}
I tried to add below property mediator with get-property expression. What is the wrong with this.
property description="" expression="get-property('message')" name="MessageValue" scope="default" type="STRING"/>

try a <log level="full"/> in your proxy def, send it a message with your java client and have a look to wso2-esb-service.log : you should see a soap message like this
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<text xmlns="http://ws.apache.org/commons/ns/payload">your|data</text>
</soapenv:Body>
</soapenv:Envelope>
You can get the text value with :
<property xmlns:tp="http://ws.apache.org/commons/ns/payload" name="MessageValue" expression="$body/tp:text"/>
