Creating a custom enterprise object (Java)

 
import com.apple.yellow.foundation.*; 
import com.apple.yellow.webobjects.*; 
import com.apple.yellow.eocontrol.*; 
import Movie; 
public class Main extends WOComponent { 
    Movie aMovie; 
    public WOComponent makeAMovie() 
    { 
        // create an instance of a Movie 
        aMovie = new Movie(null,null,null); 
        // set default values 
        aMovie.setTitle("DefaultTitle"); 
        aMovie.setRevenue(new Float("1000000")); 
        return null;  // return the updated component. 
    } 
}

Also link Movie.java into the application by adding it to the Classes folder within Project Builder. Generating Movie.java from EOModeler provides you with the common get and set methods. Additional business logic can be added directly to the Movie.java file.

Here's a portion of the Movie.java file:
