我试图在wso2框架中通过TCP发送消息.我在日志中收到此异常:

以下是启动TCP的axis2 conf:

<transportReceiver name="local" class="org.wso2.carbon.core.transports.local.CarbonLocalTransportReceiver"/>

<transportReceiver name="tcp" class="org.apache.axis2.transport.tcp.TCPTransportListener">
                <parameter name="transport.tcp.port">6060</parameter>
</transportReceiver>

和wso2.xml:

<definitions xmlns="http://ws.apache.org/ns/synapse">

    <sequence name="fault">
        <makefault>
            <code xmlns:tns="http://www.w3.org/2003/05/soap-envelope" value="tns:Receiver"/>
            <reason value="Mediation failed."/>
        </makefault>
        <send/>
    </sequence>


    <proxy xmlns="http://ws.apache.org/ns/synapse"
           name="TCPProxy"
           transports="https,http"
           statistics="disable"
           trace="disable"
