Portanto, estou ficando sem ideias para tentar realmente conectar um cliente ao serviço SOAP que estou executando através do axis2.

Tentei dois métodos, um deles era usar wsdl2java para criar o stub e as classes do lado do cliente associadas e, em seguida, escrever uma classe Client que constrói as mensagens de solicitação e as envia pelo Stub. A outra maneira era usar o ServiceClient para conectar-se.

Ambos estão falhando à sua maneira ..

Opção 1, sempre que uma mensagem é enviada pelo stub, recebo de volta:

org.apache.axis2.AxisFault: The input stream for an incoming message is null.
at org.apache.axis2.transport.TransportUtils.createSOAPMessage(TransportUtils.java:87)
at org.apache.axis2.transport.TransportUtils.createSOAPMessage(TransportUtils.java:67)

at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:229)
at org.apache.axis2.client.OperationClient.execute(OperationClient.java:165)

Opção 2, sempre que eu o executo, recebo esta exceção:

org.apache.axis2.deployment.DeploymentException: org.apache.axis2.transport.local.LocalTransportSender
