Introduction

The JOTA library is a simple Java wrapper around IOTA Node’s JSON-REST HTTP interface.

It allows to connect easily using Java directly to a local or a remote IOTA node.

• Latest release: 0.9.3

• Compatibility: fully compatible with IOTA IRI v1.4.0

• API coverage: 14 of 14 commands fully implemented

• License: Apache License 2.0

• Readme updated: 2017-09-23 21:05:02 (UTC)

A list of all IOTA JSON-REST API commands currently supported by JOTA wrapper can be found in the Commands enum (see here for more details).

JOTA java wrapper is being designed to be thread-safe and simplest as possible in order to be easily maintainable, accordingly with the ongoing natural evolution of IOTA’s API. All the boilerplate code for connecting to the node REST interface has been eliminated using Retrofit.

Technologies & dependencies

The JOTA library has been designed to be used with Java6+, in order to promote compatibility with Android.

Core dependencies:

• Retrofit Client 2.1.0

• Gson JSON Processor

• Lombok 1.16.2

Other dependencies:

• Simple Logging Facade for Java 1.7.21

• Apache Commons Lang 3.3.2

Getting started

Connecting to your local node with the default settings is quite straightforward: it requires only 2 lines of code. For example, in order to fetch the Node Info:

IotaAPI api = new IotaAPI.Builder().build();
GetNodeInfoResponse response = api.getNodeInfo();

or if you need to connect to a remote node:

IotaAPI api = new IotaAPI.Builder()
	.protocol("http")
	.host("somewhere_over_the_rainbow")
	.port("14265")
	.build();

GetNodeInfoResponse response = api.getNodeInfo();

In order to communicate with IOTA node, JOTA needs to be aware of your node’s exact configuration. If you don’t want to use the builder, the easiest way of providing this information is via a node_config.properties file, for example:

iota.node.protocol=http``****************``
iota.node.host=127.0.0.1
iota.node.port=14265
