I do something like:
public class ProductAction extends Action
{
execute()
{
String name = (String)PropertyUtils.getSimpleProperty(form,
"name");
String age = (String)PropertyUtils.getSimpleProperty(form,
"age");
ProductModel model = new ProductModel();
model.setName(name);
model.setAge(age);
model.saveToPersistentStore();
}
}
I was wondering if the ActionForm can be used as a DTO. Something like this,
public class ProductAction extends Action
{
execute()
{
ProductModel model = new ProductModel();
model.setForm(form); // action form reference which the
execute method
gets
model.saveToPersistentStore();
}
}
I do not know which method will be better. I don't even know if there is any
other technique we should follow as Oshima pointed it.
