Java SDK tutorial can't connect to hosted trial server

[justinoberle]

I am currently stuck on step 3 of the java SDK tutorial. The java code can't connect to the hosted trial server. I have tried many different things but it should be pretty straight forward. What am I doing wrong. I have followed the instructions exactly. Here is the error messages in eclipse...

for http ThingWorx environment, the uri should be ws start, but for https ThingWorx environment, the uri should be wss start.

config.setUri("ws://wc111m010.tsdevtest.ptc.com:8080/Thingworx/WS");

config.setAppKey("06ca8fa1-7833-4fad-9248-9a0b61cf01d3");

Also you need to set thing name as well:

private static String ThingName = "SimpleThing_1";

Ok my app key and thingname are correct. The URI is where I am going wrong I think. I changed it to this...

wss://PP-2007131735UF.devportal.ptc.io/Thingworx

and it is still not working. PP-2007131735UF.devportal.ptc.io/Thingworx is the link to the connection. What am I missing?

[mnarang · Accepted solution]

The URI should be wss://PP-2007131735UF.devportal.ptc.io:8443/Thingworx/WS for your case. Can you please try this ?

Thanks,
