Answer 1

Create a managed bean. Just have two input fields in jspx and an action say commandbutton.
Create two bindings for the text and password fields. Also for action, bind a method in bean.
Drag and drop any field from the VO you created and remove the fields from JSPX so that the iterator for it wil be available in pageDef
<af:inputText binding="#{beanName.name}">
<af:inputText binding="#{beanName.pass}">
<af:commandButton action="{beanName.actionMethod}">
In the actionMethod
/* Obtain view object
ViewObject vo = ADFUtils.findIterator("Iterator Name for th VO in pageDef").getViewObject();
/* Passing bind variable start
vo.setNamedWherClauseParam("cuuser",name.getValue());
vo.setNamedWherClauseParam("cupass",pass.getValue());
/* Passing bind variable end
vo.executeQuery(); // execute query
int rowCount = vo.getEstimatedRowCount(); // This will return the No of rows after executing query
