You'll also reuse the trick for populating the database, as follows.
Listing 10.2
Populating the foreign food database
public class InventoryPopulater {
private Inventory inventory;
public void setInventory(Inventory inventory) {
this.inventory = inventory;
}
public void populate() {
boolean isInventoryPopulated = (inventory.getFoodCount() > 0);
if (!isInventoryPopulated) {
inventory.createFood("Foreign Sushi", 3.45, 10);
inventory.createFood("Foreign Borscht", 1.81, 15);
}
}
}
Once again, you can use Blueprint to glue everything together, as shown in the follow-
ing listing.
Listing 10.3
Exposing your remote service

Having built your bundle, you can deploy it into your test environment along with the
API
, datasource, and persistence bundles. You can also see your remote service regis-
tered in the Service Registry (see figure 10.9).
