Axis2 always receives null parameters even if SOAP request is sent correctly?

I solved this issue by going through my WSDL file and, wherever possible, breaking down elements into their simple type counterparts and updating the references between the XML elements accordingly.

This is just a hunch, but maybe you're having a namespace issue. If you focus on this part of the wsdl, notice that your parameter has an "ns0" namespace for the elements, but in your operations defined later, it looks like you're using an "axis2" namespace. With all of my Axis2 generated WSDLs, these two namespaces are the same.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
