WSO2 ESB TCP發送消息時發生意外錯誤

2013-04-28 92 views

我在WSO2 AS上有一個AdderService。然後，我創建了運輸= 「TCP」 代理服務在WSO2 ESB：WSO2 ESB TCP發送消息時發生意外錯誤

<proxy xmlns="http://ws.apache.org/ns/synapse" name="AdderServiceTCP" transports="tcp" statistics="disable" trace="enable" startOnLoad="true"> 
    <target> 
     <outSequence> 
     <log level="full"/> 
     <send/> 
     </outSequence> 
     <endpoint> 
     <address uri="http://samplehost:9765/services/AdderService/"/> 
     </endpoint> 
    </target> 
    <description></description> 
</proxy>

我實現AdderServiceClient類像Axis2的StockQuoteClient樣品。

使用WSO2 ESB SOAP示蹤，由代理所接收的請求是：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> 
    <soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing"> 
     <wsa:To>tcp://localhost:55000/services/AdderServiceTCP</wsa:To> 
     <wsa:MessageID>urn:uuid:b3125473-064d-4a48-9cdc-558cda8e497b</wsa:MessageID> 
     <wsa:Action>urn:add</wsa:Action> 
    </soapenv:Header> 
    <soapenv:Body> 
     <p:add xmlns:p="http://ws.apache.org/axis2"> 
     <p:value1>70</p:value1> 
     <p:value2>150</p:value2> 
     </p:add> 
    </soapenv:Body> 
</soapenv:Envelope>

發送到客戶端的響應是：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> 
    <soapenv:Header xmlns:wsa="http://www.w3.org/2005/08/addressing"> 
     <wsa:MessageID>urn:uuid:ed1424f9-c181-4d9c-b203-f37e88d0b0b7</wsa:MessageID> 
     <wsa:Action>urn:mediateResponse</wsa:Action> 
     <wsa:RelatesTo>urn:uuid:b3125473-064d-4a48-9cdc-558cda8e497b</wsa:RelatesTo> 
    </soapenv:Header> 
    <soapenv:Body> 
     <ns:addResponse xmlns:ns="http://ws.apache.org/axis2"> 
     <ns:return>220</ns:return> 
     </ns:addResponse> 
    </soapenv:Body> 
</soapenv:Envelope>

因此，AS AdderService和代理正在運行好！

然而，經常發生這樣的異常在WSO2 ESB：

**我做錯了嗎？

謝謝你的幫助。**

你是否在客戶端啓用了傳輸接收器配置？看起來客戶端沒有Tcp的傳輸偵聽器。

你需要在axis2.xml中有這樣的東西。

<transportReceiver name="tcp" 
         class="org.apache.axis2.transport.tcp.TCPServer"> 
     <parameter name="port">6061</parameter>

Shelan。

在客戶端我已啓用TCP傳輸接收器和發送器：

<transportReceiver name="tcp" class="org.apache.axis2.transport.tcp.TCPTransportListener"> 
    <parameter name="transport.tcp.port">57000</parameter> 
</transportReceiver> 
<transportSender name="tcp" class="org.apache.axis2.transport.tcp.TCPTransportSender"/>

然而，使用Wireshark來監控網絡通信，即TCP端口從未使用過。我相信在客戶端啓用TCP監聽器是沒有必要的。對？

謝謝。

Shelan。

根據您的回答，我在客戶端將useSeparareListener屬性設置爲true。現在，一切正常！
