EN | ES From version 0.8.2 of the Notebook docker image (zeppelin) From this version, a client written in Java, compatible with Spark to connect to the Digital-Broker and the platform's Api-Manager, is included.  Introduction This client is developed in parallel with the  Python client  (also used for platform communication from Notebooks and applications). In this case, no installation is necessary as it is installed by default in the image of Platform Notebooks. This platform client dependency contains several classes that implement the functionalities of different platform clients: Iot-Broker Client: Queries and insertions of ontology data. Api-Manager Client: Management of REST APIs and calls. With these, clients a simple communication with the platform is established from the Platform Notebooks. Client use examples NOTE:  Very important: For each IotBrokerClient client, always do a join() at the beginning to open the connection and a leave() at the end to close it.
