Query using SDO in JDeveloper - NullPointer

Question

I have this java lines for query:
DocsOddcModuleServiceImpl docs = new DocsOddcModuleServiceImpl();
FindCriteria findCriteria = new FindCriteriaImpl();
FindControl findControl = new FindControlImpl();
DocsOddcVOSDOResult result = docs.findDocsOddcVO1buscarDocsOddcPorIdInstancia(findCriteria, 1L, findControl);
List resultList = result.getValue();
int total = resultList.size();
System.out.println("total eh " + total);
Problem: at this line "DocsOddcVOSDOResult result = docs.findDocsOddcVO1buscarDocsOddcPorIdInstancia(findCriteria, 1L, findControl);" i get a nullpointer exception.

I have a simple table at oracle database, i use the jdeveloper to generate a View Object / View Criteria and Service Interface (SDO), and i want to make a simple query:
Select * from table where idInstancia = "idInstancia" (Bind Variable - Type - Long)
I am feeling that my problem is at findCriteria and findControl. I instantiate these variables, but i'm not populating.
Should i use the setter method ? What ?
Thanks

Yeah, you are right on, if you haven't guessed it in the last couple of months ;-)
fecthStart, fetchSize, and excludeAttribute are all required property for FindCriteria.
retrieveAllTranslations is a required property for FindControl.
