Unable to read the properties from JAVA SDK into Core

Hi,

I am using Java SDK to push data into thingworx. I created a thing  in Core with the name same as that of thing in JAVA SDK.  When I start my SDK , the connection between Core and SDK is established and I see that isConnected property of remote thing is set to true. After few seconds the connection drops/closed and I am unable to do manage bindings for remote thing which is required to capture values from SDK. Below are the logs. Can anyone help me to whats wrong I have done here.

NOTE : I am using trial version of thingworx foundation server that is on remote machine.

Re: Unable to read the properties from JAVA SDK into Core

Bob, is the clientConfiguration configured to attempt connections every ​n ​ number of seconds/minutes? Could share your code or pseudo code how the property is being updated?

Re: Unable to read the properties from JAVA SDK into Core

If it helps, here's the sample code to initiate the connection and keep attempting it every few seconds i used in one of my project :

public class ClinetConfigurator {

  private static final Logger LOG = LoggerFactory.getLogger(ClientConfigurator.class);

  public static Random random = new Random();

  public static void main(String[] args) {

  try {

  // Setting the server URL and the appkey to enable this client to

  // connect to the ThingWorx platform

  //Applicaton server on TWX70

Hi Sushant,

Below is the code for client and Virtual Thing

Client.

     throws Exception

   {

     int scanRate = 30000;

   

     RollingStockClient client = new RollingStockClient(masterconfig.config);

   

     RollingStockThing rollingStockThing = new RollingStockThing("RemoteRollingStock", "RollingStock", client);

   

     client.bindThing(rollingStockThing);

     try

     {

       System.out.println(masterconfig);

       client.start();

     }

     catch (Exception eStart)

     {

       System.out.println("Initial Start Failed : " + eStart.getMessage());

     }

Re: Unable to read the properties from JAVA SDK into Core

Hi Sushant,

Thanks for sharing the above code. But this did not helped me. I am still facing the same issue.

Re: Unable to read the properties from JAVA SDK into Core

Hi Sushant,

There was one mistake in my code. I was not setting uri of actual thingworx core rather it was by default pointing to local. I made the changes as below

this.config = new ClientConfigurator();

this.config.setUri("ws://13.113.122.50:80/Thingworx/WS");

But after this I am getting another error. Please have a look at trace below.

Any idea?

Re: Unable to read the properties from JAVA SDK into Core

Is the server already reachable for you? because I can't get to the authentication page for your server's IP. So you might want to hold on till the IP is reachable again and secondly I can't see that your server instance is defining port 80 so you test removing that once the server is responding again.

bob argo​,

Just to add if it's secured connection; in uri it would be wss instead of ws.
