Я установил GridDB в Ubuntu. Я использую 2 компьютера: первый компьютер используется как сервер GridDB, второй - как клиент java, и когда я пытаюсь подключиться к GriDB со второго компьютера, выдается исключение, но когда я запускаю код java на стороне сервера, он работает совершенно нормально. В чем проблема? Я использую учебник .
Вот простой java код:
import java.util.Arrays;
import java.util.Properties;
import com.toshiba.mwcloud.gs.Collection;
import com.toshiba.mwcloud.gs.GSException;
import com.toshiba.mwcloud.gs.GridStore;
import com.toshiba.mwcloud.gs.GridStoreFactory;
import com.toshiba.mwcloud.gs.Query;
import com.toshiba.mwcloud.gs.RowKey;
import com.toshiba.mwcloud.gs.RowSet;
// Operaton on Collection data
public class Sample1 {
static class Person {
@RowKey String name;
boolean status;
long count;
byte[] lob;
}
public static void main(String[] args) throws GSException {
// Get a GridStore instance
Properties props = new Properties();
props.setProperty("notificationAddress", "239.0.0.1");
props.setProperty("notificationPort", "31999");
props.setProperty("clusterName", "defaultCluster");
props.setProperty("user", "admin");
props.setProperty("password", "admin");
GridStore store = GridStoreFactory.getInstance().getGridStore(props);
// Create a Collection (Delete if schema setting is NULL)
Collection<String, Person> col = store.putCollection("col01", Person.class);
}
}
Вот исключение, когда я пытаюсь подключиться со второго компьютера:
