啓用WSO2 ESB的TCP傳輸

我正在試驗WSO2 ESB支持的不同傳輸。我想爲WSO2 ESB啓用TCP傳輸。我已經下載了axis2-transport-tcp-1.0.0.jar並將其放入ESB_HOME/repository/components/lib。我設法啓用運輸發件人加入啓用WSO2 ESB的TCP傳輸

<transportSender name="tcp" class="org.apache.axis2.transport.tcp.TCPTransportSender"/>

到axis2.xml配置文件。爲了使傳輸接收機我添加了一個類似線

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

但是這個失敗，當我重新啓動WSO2 ESB來初始化傳輸接收機。相反，我得到一個InstantiationError：

org.apache.axis2.AxisFault: Exception occured while loading the Axis configuration from /usr/local/wso2esb/repository/conf/axis2/axis2.xml

我試過在axis2.xml但沒有提供端口號參數改變。

我試圖追蹤錯誤。由於沒有參數構造函數，類對象似乎不能被實例化。但我使用相同的jar文件運行下面的示例中沒有任何錯誤：

String className = "org.apache.axis2.transport.tcp.TCPServer"; 
Class receiverClass; 

receiverClass = Loader.loadClass(className); 

TransportListener receiver = (TransportListener) receiverClass.newInstance();

我想這是一個整合的問題，但我不能拿出任何解決方案。

要啓用TCP傳輸，您不必添加「axis2-transport-tcp-1.0.0.jar」它的nessasary庫隨附WSO2 ESB。

所有您需要做的就是去提供axis2.xml在

ESB_HOME/repository/conf/axis2/axis2.xml

，並添加下面的塊傳輸發送和傳輸Reciver 在這裏你可以通過添加

<parameter name="transport.tcp.port">6060</parameter>

添加TCP端口

如下所示。對於傳輸接收機

<!-- Enable TCP message --> 
<transportReceiver name="tcp" class="org.apache.axis2.transport.tcp.TCPTransportListener"> 
    <parameter name="transport.tcp.port">6060</parameter> 
</transportReceiver>

要增加運輸發件人

<transportSender name="tcp" class="org.apache.axis2.transport.tcp.TCPTransportSender"/>

謝謝你， Dharshana。

我想我已經使用org.apache.axis2.transport.tcp.TCPServer而不是org.apache.axis2.transport.tcp.TCPTransportListener。官方文檔沒有在XML聲明中指定任何類，並指定org.apache.axis2.transport.tcp.TCPServer是實現類。那是誤導我的。 – infiniteRefactor
