TCPTransportSender cannot be found by axis2_1.6.1.

问题:

I am upgrading WSO2 DSS 3.2.2 server to 3.5.0, but I am eventually getting this error:

Caused by: java.lang.ClassNotFoundException: org.apache.axis2.transport.tcp.TCPTransportSender cannot be found by axis2_1.6.1.wso2v15

    at org.apache.axis2.deployment.AxisConfigBuilder.processTransportSenders(AxisConfigBuilder.java:686)

Is this a configuration problem or do I need to add a particular JAR library? If yes, which one?

Edit: I have just found that axis2_1.6.1.wso2v10.jar has this org.apache.axis2.transport.tcp.TCPTransportSender class but axis2_1.6.1.wso2v15.jar doesn't.

This error was solved by adding axis2-transport-tcp-1.0.0.jar to ..repository/components/dropins.
