Re: Sending a Collection of objects (advanced :-))

[Anne Thomas Manes]

You should convert all collections to arrays -- especially if your goal is interoperability with non-Java applications. As an alternative to doing the class clasting in your code, you could write your own schema for the information and custom serializers.

Hi,
after several hours I've solved the probem how to send a java collection over soap ("Wrapper" pattern):

public class CustomerManager {

    private Set<Customer> customers = new HashSet<Customer>();

    public Set<Customer> getCustomers() {
        customers.add(new Customer(21, "Paul"));
        customers.add(new Customer(22, "Peter"));

        return customers;
    }

Wrapper:
-------------
public class CustomerManagerWrapperSoapBindingImpl implements test.CustomerManagerWrapper{

    protected CustomerManager cm = new CustomerManager();

    public test.Customer [] getCustomers() throws java.rmi.RemoteException {
        return (Customer[]) cm.getCustomers().toArray(new Customer[0]);
    }
}

Well, works fine, but only when the Customer class has only "primitive" atributes.
But I want to apply this pattern on Customers which includes another collection (I use Hibernate, collections means one-to-many mapping for example):

// for example
private Set kids;

Is there any possible way except creating another wrapper (around Customer class)?

Thanks for any comments
