More details are here: Also, read this blog post: Object-Oriented Java Adapter of Amazon S3 SDK.

It's an object layer on top of Amazon S3 SDK:

import com.jcabi.s3.Bucket;
import com.jcabi.s3.Ocket;
import com.jcabi.s3.Region;
import com.jcabi.s3.cached.Region;
public class Main {
  public static void main(String[] args) {
    Region region = new CdRegion(
      new Region.Simple("key", "secret")
    Bucket bucket = region.bucket("");
    Ocket.Text ocket = new Ocket.Text(bucket.ocket("test.txt"));
    String content =;
    ocket.write("hello, world!");

It is highly recommended to use CdRegion to avoid multiple duplicate reads from the same S3 object.
