pojogen-maven-plugin

["M. Ali Khemila" <mk...@icloud.com>]

Hi,

Is anybody familiar with the pojogen-maven-plugin? I can’t find any supporting documentation.

I was able to use the plugin to generate the Java code and run the following example to display my customers list

public class Example {
	
	private static final String SERVICE_ROOT="http://services.odata.org/V4/Northwind/Northwind.svc";

	public static void main(String args[]) {

		Service<EdmEnabledODataClient> service = Service.getV4(SERVICE_ROOT);
		NorthwindEntities container = service.getEntityContainer(NorthwindEntities.class);
		Customers customers = container.getCustomers();
		for (Customer c : customers) {
			System.out.println(c.getCustomerID() + " - " + c.getCompanyName());
			
		}
	}
}


These are the questions I have:
1/ Is customers list found lazily? Obviously, when I call 'container.getCustomers();’ I don’t want all the customers to be loaded at once.
2/ How can I update the name of a specific customer. I tried this:
c.setCustomerName(“NewName”);
container.flush();

And I got the exception below. Please help if you have an idea!!! Many thanks!!
