SOAP Response Returning NULL

Question

I am communicating with a SOAP webservice, through the IDE I can execute the calls of the methods and capture the values perfectly, however, by executing the . jar generated by Intellij, all returns are null... I have tried to generate . jar by Maven, I have no idea what it might be...

Example of one of the methods I’m using:

    @WebMethod(operationName = "InserirVenda", action = "Linker20/InserirVenda")
@WebResult(name = "InserirVendaResponse", targetNamespace = "Linker20", partName = "parameters")
public InserirVendaResponse inserirVenda(
        @WebParam(name = "InserirVenda", targetNamespace = "Linker20", partName = "parameters")
                InserirVenda parameters);
