Hello All,

After searching in simpleUI5dashboard project in SAP IDE. Got following solution.

1.Deploy simpleSensortag.war in Java Application of HANA cockpit.Please keep the application name same as it is i.e.simpleSensortag.

(Error occurred due to name change of application during deployment of war file. So wsManager.js giving "websocket exception error during websocket handshake unexpected response" checked in page inspect feature)

2.Import  simpleUI5dashboard in SAP WebIDE & Deploy on HCP.

Sensor data will come on Dashboard directly.So problem resolved.

I'm not able to run the UI5 dashboard. Still getting the error "connection dropped".

I did not rename the java application during .war file upload.

By the way the application can not be named like "simpleSensortag" (as propsed by you) since capital letters are not allowed. So I named it "simplesensortag" as propsed from the .war file. Furthermore I changed the application name in wsManager.js file like this:

NEW:

var wsUriWS = "wss://" + host + "/simplesensortag/ws";

OLD:

var wsUriWS = "wss://" + host + "/simpleSensortag/ws";

Anyhow I doesn't worked out.

Could you please give some advices how to fix it.

Thank you.

Hello @Pavan Hampi,

I've tried your solution, but still face some problems:

1.Deploy simpleSensortag.war in Java Application of HANA cockpit.Please keep the application name same as it is i.e.simpleSensortag.

I agree with @Cornelius Jaeckel,  That seems not possible, only lower case is supported:

So I changed it to: simplesensortag

Now the situation is that the simpleSensortag page works：

But the dashboard page still Error:

Hello ,

1.Have you deployed Dashboard application on HCP ?.

I tried on my android device.it fetches as per sensor provides data.

2.Have you installed Evothings client on your device?This client will work as bridge between TI sensor and HCP. Please try this. As per your 1st screenshot you getting data in gauge.Scan the QR code,it will generate like "evothings://simplesensortag--------.us1.hana.ondemand.com/simpleSensortag/bridge-st/index.html"(this is my auto generated URL). Open this link.You will get following

Hi,

I got it working by (in wsManager.js) eliminating not only ".dispatcher" from the host variable, but "l.dispatcher".

The thing is: the Java application is deployed at simplesensortagp<insert 10-digit p-number>tria.hanatrial etc. So "trial", right after your p-number was truncated because apparently it can't be longer than 30 characters.

Hope this helps...

BR, Fred

Fred is right. The application URL for simplesensortag is incorrect (in the war file)

https://simplesensortags000xxxxxtria.hanatrial.ondemand.com/simpleSensortag

I'ts missing an L for triaL....

Sorry, but Question seem not be be answered.

As I have imported and deployed like a above.

Java App is running fine

but UI5 App says "Connection Dropped" and I do not find a solution here.

Where do I find a step-by-step fix?

Hi Pavan,

I deployed simplesSensortag.war and kept the same Name. (w/o an capital S, as discussed above)

The application workd fine.

Then I imported simpleUI5dashboard in the WebIDE and deployed it to HANA and I geht the message "Connection dropped"

Now I am looking into wsManager.js as suggested by Fred. There I find one line with

host = host.replace(oldhost, "simplesensortag").replace(".disptacher","");

Do I just remove ".disptatcher" to

host = host.replace(oldhost,"simplesensortag").replace(,"");  ? or how does it should look like?

and where do I find "I.disptatcher" ? I can't find it in the source.

thanks in advance.

regards

Hi Fred,

could you help/advice (See below)

[fred_verheul · Accepted solution]

Here is the line after I changed it in wsManager.js:

host = host.replace(oldhost,"simplesensortag").replace("l.dispatcher","");

Hope this helps, don't recall the details anymore (and don't have time to dive back in).
