A client has a requirement to get the location of stores based on the zip code authored in the component dialog. Location needs to be pulled from an external API using OSGi services.

Which OSGi Service code snippet should be used to represent the requirement?

A)

@OSGIService(component = Service.class)

public class ServiceImpl implements Service {

@Override

public List getStoresByZipCode(String zipCode) {

List storeLocations = new ArrayList<>();

// Create an HTTP client

try (CloseableHttpClient httpClient = HttpClients.createDefault()) {

// Processing logic to get all the locations from external api

} catch (IOException e) {

}

return storeLocations;

}

}

B)

@Component(service = Service.class)

public class ServiceImpl implements Service {

@Override

public List getStoresByZipCode(String zipCode) {

List storeLocations = new ArrayList<>();

// Create an HTTP client

try (CloseableHttpClient httpClient = HttpClients.createDefault()) {

// Processing logic to get all the locations from external api

} catch (IOException e) {

}

return storeLocations;

}

}

C)

@Service(service = Component.class)

public class ServiceImpl implements Service {

@Override

public List getStoresByZipCode(String zipCode) {

List storeLocations = new ArrayList<>();

// Create an HTTP client

try (CloseableHttpClient httpClient = HttpClients.createDefault()) {

// Processing logic to get all the locations from external api

} catch (IOException e) {

}

return storeLocations;

}
