Programmatically execute view criteria in ADF (With two different Approaches ) part 1

Hi everyone in this post we will see two different approaches to call the view criteria Programmatically

1) In First Method we can execute View criteria in AppModuleImpl Class
2) In Second Method we can also do the same thing in View object Impl class with less code

1) Execute Through AppModuleImpl class

Suppose you create a view criteria , 'select employees where departmetnId =:bind_parameter' on EmployeesView

To create view criteria just click on query tab of EmployeesView
1) Then click on green + icon of view criteria
2) Then click on group and select Add items
3) Then Select "DepartmentId" from Attributes
4) Then create a bind parameter by click on green + icon

Now to generate AppModuleImpl class gust select java tab of AppModule
then click on pencil icon
and select the check box just like in the following pic

Now at the end of AppModuleImpl class write the following method

Now call this method in been and pass the parameter in been
