Step 9: File TransferStep 10: TroubleshootingStep 11: Tunneling ExampleStep 12: Next Steps  Step 9: File Transfer  To handle file transfers, create a virtual directory in the FileTransferExample Entity and in the project directory. The source code used for this example is found in com.thingworx.sdk.examples.FileTransferExample.java. Set Up File Transfer Right-click the project. Click New. Scroll and select Folder.Enter transfer/incoming into the text box at the bottom. Click Finish.Repeat steps 1 and 2, but create a folder called transfer/outgoing.Right-click the transfer/outgoing folder. Click New. Scroll and select File.Create a file with the name outgoing.txt.

Step 7: Delivery Truck ModelStep 8: Services and Events Step 7: Delivery Truck Model  In the Delivery Truck application, there are three Delivery Truck Things. Each Thing has a number of Properties based on its location, speed, and its deliveries carried out. In this design, when a delivery is made or the truck is no longer moving, the property values are updated. The DeliveryTruckThing class extends the VirtualThing class and based on the DeliveryTruck Entities in the Composer. After extending VirtualThing, there are a number of steps necessary to get going. For the DeliveryTruckThing and SimpleThing classes, there are a number of methods for creating Properties, Events, Services, and Data Shapes for ease of use. The constructor for the DeliveryTruckThing takes in the name of the Thing, the description of the Thing, and the ConnectedThingClient instance used to make the connection. It then sends these values to the VirtualThing constructor as sh

Step 6: Power Grid Example  Step 6: Power Grid Example In the Power Grid application, there are three Generator Things and three Consumers. Each Thing has a number of Properties based on its location, wattage, and its power lines provided with power. In this design, when a generator goes offline, comes back online, or one of the other power grid aspects are updated/created/deleted, the Property values are updated. The GeneratorThing class extends the VirtualThing class and based on the Generator entities in the Composer. After extending VirtualThing, there are a number of steps necessary to get going. For the GeneratorThing and SimpleThing classes, there are a number of methods for creating Properties, Events, Services, and Data Shapes for ease of use. The constructor for the GeneratorThing takes in the type of electricity generator, name of the Thing, the description of the Thing, and the ConnectedThingClient instance used to

Step 3: Test ConnectivityStep 4: Run Sample ApplicationsStep 5: Example Client Connection  Step 3: Test Connectivity  Before you can begin developing with the ThingWorx Java SDK, you will need to generate an Application Key and add it to the source code provided. Generate Application KeyOn the Home screen of Composer click + New the top left.  In the dropdown list, click Application Key. Give your Application Key a name (i.e., MyAppKey) and set the Project (ie, PTCDefaultProject).Assign the application key to a User. Click Save.After saving, a Key ID is generated and appears above the Expiration Date. This is the secret key that you will use to make secure connections. If you have not updated the Expiration Date field, the default will be one day.This is an example of the Application Key ID that you will use for a successfull connection. NOTE: Using the Application Key for the default Adminis

Step 11: UsersStep 12: TroubleshootingStep 13: Authentication TagsStep 14: Next Steps Step 11: Users Access to functions and information on the ThingWorx Foundation server is controlled by Users. The REST API can be used to create, list, and delete Users. Get Usernames of all Users The REST API exposes the ability to retrieve collections of Entities so that a UI can be dynamically updated with current data. Required Parameters AppKey created by your Foundation serverRequest Construct the URL. Include the hostname and authentication credentials for your specific ThingWorx server as described below. The Usernames of all Users can be returned by making a GET request to this endpoint: 〈Server IP:port〉/Thingworx/UsersAuthenticate Request. All API requests to the ThingWorx server must be authenticated either with a username and password or with an appKey. For this example we will authenticate by passing the appKey as a URL query string parameter. The parame

Step 8: Call Custom ServiceStep 9: Import and Export EntitiesStep 10: Authentication Tags   Step 8: Call Custom Service   In order to execute a Service of a specific Thing with the REST API, you can use the POST verb.   Required Parameters:   AppKey created by your ThingWorx server Name of the Thing that implements a custom Service Name of the custom Service Names of inputs, if any, required by the Service Request   Construct the URL. To call a custom Service of an existing Thing, make an HTTP POST to this endpoint: <server_ip:port>/Thingworx/Things/<name of Thing>/Services/<name of Service> Substitute <name of Thing> with the actual name of a Thing that exists on the ThingWorx server, and <name of Service> with an existing Service.
