Java SOJO CSV Serialization

Question

I am trying to use SOJO to serialize a Java object to CSV. The example looks pretty straight forward:

Car car = new Car("My Car");
car.setDescription("This is my car.");
Serializer csvSerializer = new CsvSerializer();
String csvStr = (String) csvSerializer.serialize(car);
System.out.println(csvStr);
// print:
// description,build,properties,name,~unique-id~,class  
// This is my car.,,,My Car,0,test.net.sf.sojo.model.Car

I tried implementing my own version of the example. I made a really simple Car class with two String fields (build and description) which implements a setDescription(..) method.

This is what I implemented:

import net.sf.sojo.interchange.csv.CsvSerializer;


public class Main {

private class Car
{
    private String build;
    private String description;
    public Car(String build) {
        this.build = build;
        this.description = null;
    }

    public void setDescription(String description) {
        this.description = description;
    }


}

public static void main(String[] args) {
    Main m = new Main();
    Car car = m.new Car("My Car");
    car.setDescription("This is my car.");
    CsvSerializer csvSerializer = new CsvSerializer();
    String csvStr = (String) csvSerializer.serialize(car);
    System.out.println(csvStr);
}

}

However, when I run my implementation I get the following output:

~unique-id~,class,description
0,Main$Car,

I don't understand why in my implementation neither the build or description fields are serialized, can you help?

Cheers,

Pete

From the SOJO home page: "The intention for this project is a Java framework, that convert JavaBeans in a simplified representation"

The Car object in your example does not qualify. You must have a getter (and, probabaly, a setter as well) for every property that you wish SOJO to write to (or read from) your file. Add getBuild() and getDescription()

Yes, It does to work without the setters, even public fields without setters dont prints out to CSV.

I haven't used SOJO, but for private fields you probably need getter methods; or you could try declaring the fields public.
