GWT,RPC & Datasources

Smart GWT Technical Q&A
1

I am a new smartGWT user and confused about how to use GWT RPC to create a Data Source that I can later use the data in smart grids and forms. I have the following working method:

public class ContactList {

public ContactList() {
	contactService.listContacts(new AsyncCallback<List<Contact>>() {
	
public void onFailure(Throwable caught) {
		System.out.println("Failure:" + caught);
		}
	
public void onSuccess(List<Contact> result) {
		try {
			int row = 0;
			for (Contact contact : result) {
			System.out.println("Row" + row + " "
				      + contact.getName() + " " 
                                      + contact.getEmail()
                                      + contact.getPhone());
			row++;
					}
				} catch (Exception e) {
					
				}

			}
		}// end of inner class
	    );
	}

What is the best way to get the data from the returned List<Contact>
to a DataSource. Do I need to use the loop and create a separate records and then assign them to the DataSource? i.e.

for (Contact contact : result) {
	    ListGridRecord record = new ListGridRecord();
	    record.setAttribute("name", contact.getName());
	    record.setAttribute("email",contact.getEmail());
	    record.setAttribute("phone", contact.getPhone());
ds.addData(record);
}

Any help would be much appreciated.

You seach the forums for GwtRPCDataSource, it allows you to write your RPC as normal but it will act in the same fashion as a normal datasource. The code can be found in the smartgwt-extensions project.

Thanks, I will look more into GWTRPC.
