Unable to create table: Unable to execute HTTP request

It is failing me when creating a table, the code is this:

public class MoviesCreateTable {

    public static void main(String[] args) throws Exception {

        AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard().withEndpointConfiguration(
                new AwsClientBuilder.EndpointConfiguration("http://localhost:8000", "us-east-2")).build();
        System.out.println("registra bien");
        DynamoDB dynamoDB = new DynamoDB(client);
        System.out.println("se conecta con la bdd");
        String tableName = "Movies";

        try {
            System.out.println("Attempting to create table; please wait...");
            Table table = dynamoDB.createTable(tableName, 
                    //partition key
                    Arrays.asList(new KeySchemaElement("year", KeyType.HASH), new KeySchemaElement("title", KeyType.RANGE)), // Sort key
                    
                    Arrays.asList(new AttributeDefinition("year", ScalarAttributeType.N),new AttributeDefinition("title", ScalarAttributeType.S)),
                    new ProvisionedThroughput(10L, 10L));
            table.waitForActive();
            System.out.println("Success.  Table status: " + table.getDescription().getTableStatus());

        } catch (Exception e) {
            System.err.println("Unable to create table: ");
            System.err.println(e.getMessage());
        }

    }
}

This is the log I get:

registra bien
se conecta con la bdd
Attempting to create table; please wait...
Unable to create table: 
Unable to execute HTTP request: Connect to localhost:8000 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused: connect

EDIT2 : I HAVE FOUND THE SOLUTION IN CASE SOMEONE SERVES HIM,

I have simply removed the client line, because there I was testing on localhost and I have replaced it with this:

AmazonDynamoDB client = AmazonDynamoDBClientBuilder.standard()
.withRegion(Regions.US_WEST_2)
.build();
