Hello guys! I found the reason of our problem
When I use SOAP Wizard I get classes generated automatically, one of these classes contains all parameters of my wsdl.
Here was the problem, I don't know why, but theses parameters were generated with a specific order, and when we use its endpoint in Java, as a consequence of this order, the application didn't work because it always expect another order of parameters, it was incompatible.
We changed the order for these parameters and It worked!!
But I am not able to explain why SoapUI is not affected by this on the contrary with Java's aplication
