org.apache.axis2.AxisFault exception - Operation not Found

[Constantinos Grevenitis]

The exception that I get is this one:

org.apache.axis2.AxisFault: The getSOAPMessage operation cannot be found.
at org.apache.axis2.client.ServiceClient.createClient(ServiceClient.java:584)
at org.apache.axis2.client.ServiceClient.sendReceiveNonBlocking(ServiceClient.java:560)
at eKONES.client.Client.main(Client.java:70)

==============================================================================

The problem problably has to do with QName. Also I would like to explain what setAction("urn:echo") is, and what kind of args setAction() can get. I also give you services.xml
