Passing multiple variables from servlet to client

Question

I hope someone can assist me with this. I'm trying to pass an customer id and customer name from a database result using rpc in gwt to the client. I found a way to pass one variable but I can't find a way to pass them both where the id is attached to the name. Can someone post a code example on how to do this. If you need more info let me know.

Answer 1

That is a simple java limitation. Just wrap the 2 fields in an object.

Answer 2

As David Nouls said, you could just use an object, e.g.

import com.google.gwt.user.client.rpc.IsSerializable;

public class Customer implements IsSerializable {
    private String id;
    private String name;

    public Customer(String id, String name) {
        this.id = id;
        this.name = name;
    }

    public void setId(String id) {
        this.id = id;
    }
    public String getId() {
        return id;
    }

    public void setName(String name) {
        this.name = name;
    }
    public String getName() {
        return name;
    }
}
