java-manta is the Java SDK for interacting with Joyent's Manta system.

At present, this SDK only supports the Manta data plane, and not the Manta compute component.

• Java 1.6 or higher.
• Maven

Add the latest java-manta dependency to your Maven pom.xml.

<dependency>
    <groupId>com.joyent.manta</groupId>
    <artifactId>java-manta</artifactId>
    <version>1.5.0</version>
</dependency>

If you prefer to build from source, you'll also need Maven, and then invoke:

# mvn package

Which will compile the jar to ./targets/java-manta-version.jar. You can then add it as a dependency to your Java project.

You'll need a manta login, an associated rsa key, and its corresponding key fingerprint. Note that this api currently only supports rsa ssh keys -- enterprising individuals wishing to use dsa keys can contribute to this repo by consulting the node-http-signing spec.

For detailed usage instructions, consult the provided javadoc.

import java.io.IOException;

import com.joyent.manta.client.MantaClient;
import com.joyent.manta.client.MantaObject;
import com.joyent.manta.client.MantaUtils;
import com.joyent.manta.exception.MantaCryptoException;

public class App {
        private static MantaClient CLIENT;
        private static final String URL = "https://us-east.manta.joyent.com";
        private static final String LOGIN = "yunong";
        private static final String KEY_PATH = "src/test/java/data/id_rsa";
        private static final String KEY_FINGERPRINT = "04:92:7b:23:bc:08:4f:d7:3b:5a:38:9e:4a:17:2e:df";

        public static void main(String... args) throws IOException, MantaCryptoException {
                CLIENT = MantaClient.newInstance(URL, LOGIN, KEY_PATH, KEY_FINGERPRINT);
                MantaObject gotObject = CLIENT.get("/yunong/stor/foo");
                String data = MantaUtils.inputStreamToString(gotObject.getDataInputStream());
                System.out.println(data);
        }
}

For more examples, check the included unit tests.

The SDK utilizes log4j, and logging can be configured via the usual methods. The underlying google-http-java-client utilizes java.util.logging.Logger, which can be configured accordingly.

Contributions welcome! Please ensure that # mvn checkstyle:checkstyle runs clean with no warnings or errors.
