Question

Error when deploying EMS with Pi temp humidity sensor.

(I am not the administrator for my instance)

In part 5 of the Raspberry Pi Weather Application project, I get an error when trying to connect the Pi to ThingWorx. the commands I ran are:

java -jar ./temperature-thing-jar-with-dependencies.jar ws://xxxxxx.clould.thingworx.com:80//Thingworx/ws b7b95994-865b-446c-ace7-b9438bdf1d80

and

java -jar ./temperature-thing-jar-with-dependencies.jar wss://xxxxxx.clould.thingworx.com//Thingworx/ws b7b95994-865b-446c-ace7-b9438bdf1d80

Also, when I run the simulated command from my desktop, I receive the message that the system cannot find the file, but the .jar file is clearly where it is supposed to be. Any help will be appreciated. The errors from the Pi and Windows are shown below:

From my Desktop:

C:\temperature-thing\temperature-thing\target>java -jar ./temperature-thing-jar-with-dependencies.jar wss://xxxxxxxx.cloud.thingworx.com//Thingworx/WS</thingworx b7b95994-865b-446c-ace7-b9438bdf1d80 simulated

The system cannot find the file specified.

C:\temperature-thing\temperature-thing\target>java -jar C:\temperature-thing\temperature-thing\target/temperature-thing-jar-with-dependencies.jar wss://xxxxxxxxx.cloud.thingworx.com//Thingworx/WS</thingworx b7b95994-865b-446c-ace7-b9438bdf1d80 simulated

The system cannot find the file specified.

From my Pi:

Hi


1st question is the instance that you are connecting to HTTP or HTTPS?

2nd question : are you running the command on the pi from the directory where the jar file resides? I'll assume that you are....


If your ThingWorx instance is HTTP, then:

java -jar temperature-thing-jar-with-dependencies.jar ws://xxxxxx.clould.thingworx.com:80/Thingworx/ws b7b95994-865b-446c-ace7-b9438bdf1d80


Should work.


If it's HTTPS (and using default HTTPS port) then:

java -jar temperature-thing-jar-with-dependencies.jar wss://xxxxxx.clould.thingworx.com:443/Thingworx/ws b7b95994-865b-446c-ace7-b9438bdf1d80


should work.


In both cases I've taken out the ./ before the jar file name (as I'm assuming you're in that directory) and changed // to / before "Thingworx" in the URL. For the HTTPS example I've also added the port to the URL.


In the windows example, it won't like the ./ so take that out and also make the same updates to your URL as above.


Regards


Ian

After making the suggested changes and ensuring the instance is http and that I am running the command from the proper directory, the problem still persists. I am at a loss of where I can go from here. Could it be the settings on my schools network? Do the steps that take place on ThingWorx have to be done as an administrator? My results are below, thank you.
