Java for IBM Watson IoT Platform

Overview

• Logging powered by SLF4J
• HTTP API support is provided by swagger-codegen. See com.ibm.wiotp.sdk.swagger

Documentation

Usage

Add a dependency on com.ibm.wiotp.sdk to your project's pom.xml:

<dependency>
  <groupId>com.ibm.wiotp</groupId>
  <artifactId>com.ibm.wiotp.sdk</artifactId>
  <version>0.5.0</version>
</dependency>

Applications

Simple example that initialises an application client from environment variables, connects, sends 1 command to a device, and then disconnects.

import com.google.gson.JsonObject;
import com.ibm.wiotp.sdk.app.ApplicationClient;
import com.ibm.wiotp.sdk.codecs.JsonCodec;

class simpleTest {
	public static void main(String[] args) {
		ApplicationClient appClient = new ApplicationClient();
		appClient.registerCodec(new JsonCodec());
		appClient.connect();
		JsonObject data = new JsonObject();
		data.addProperty("distance", 10);
		appClient.publishCommand("myDeviceType", "myDeviceId", "myCommand", data);
		appClient.disconnect();
	}
}

Devices

Simple example that initialises a device client from environment variables, connects, sends 1 event, and then disconnects.

import com.google.gson.JsonObject;
import com.ibm.wiotp.sdk.device.DeviceClient;
import com.ibm.wiotp.sdk.codecs.JsonCodec;

class simpleTest {
	public static void main(String[] args) {
		DeviceClient deviceClient = new DeviceClient();
		deviceClient.registerCodec(new JsonCodec());
		deviceClient.connect();
		JsonObject data = new JsonObject();
		data.addProperty("distance", 10);
		deviceClient.publishEvent("myEvent", data);
		deviceClient.disconnect();
	}
}
