Hi,
SAP offers an example on github (https://github.com/SAP/iot-starterkit/tree/master/src/apps/java/consumption) for a java/UI5 application that should display the values of IoT-devices. The IoT-devices are managed through the HCP Internet of Things Service.
Using the Message Management Service (MMS) Cockpit I can send messages to a message management service and I can see the stored messages, using "Display stored messages" in the MMS Cockpit (for different devices and different message types).
After uploading and starting the iotstarterkit application I can access the application, but for some message types I get the error "500 Internal Server Error A Table with the name [T_IOT_%message_id%] does not exist in the data base. Please, send some messages of type %message_id% first on behalf of the device".
The table is definitely there, since I can see it in the MMS cockpit and also in the table catalog.
For other message types I can see (using developer tools in firefox) incoming json files, containing some data, but only old messages, that I send some days ago. Messages I just sent from the device are not in the json files. The MMS cockpit shows the new incoming messages immediately.
Thought the json files coming in, the application doesn't display the received values on the web page
Has someone any idea, what's going wrong in my application?
Thanks a lot,
Stefan
