在wso2 ESB中，向TCP请求发送请求时，出现以下异常。

我已经配置了axis2.xml

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

API代码：

<?xml version="1.0" encoding="UTF-8"?>
<api context="/testtcp" name="testtcp" xmlns="http://ws.apache.org/ns/synapse">
    <resource methods="POST">
        <inSequence>
            <log level="full"/>
            <property name="OUT_ONLY" scope="default" type="STRING" value="true"/>
            <property name="ContentType" scope="axis2" type="STRING" value="text/plain"/>
            <send>
                <endpoint>
                    <address uri="tcp://localhost:6060"/>
                </endpoint>
            </send>
        </inSequence>
        <outSequence>
            <log level="full"/>
            <send/>
        </outSequence>
        <faultSequence/>
    </resource>
</api>

根据他们提到的有关肥皂请求的文档，所以可以发送文本/纯文本。
