Deploy CAP Java App to BTP - No authentication method found

[SebastianKazuch]

Hello, 

I am fallowing tutorial https://developers.sap.com/tutorials/cp-cap-java-deploy-cf.html#2af0294a-493a-4800-99b5-e2e7e0ecc396 and I am not able to deploy the application due to issue with "bookstore-db-deployer". 

The issue began when with not finding the database. 

The mta had configuration : 

  - name: bookstore-db
    type: com.sap.xs.hdi-container
    parameters:
      service: hana
      service-plan: hdi-shared

After launching it it was not able to find the service correctly since the trial setup db on different service and plan. After I change it to 

  - name: bookstore-db
    type: com.sap.xs.hdi-container
    parameters:
      service: hana-cloud-trial
      service-plan: hana​

It started launched but had issue with "bookstore-db-deployer". After inspecting the logs I found those: 

Not a hana service or user-provided service with hana tag (STDOUT, APP/TASK/deploy)#
Using hdb@undefined for connection (STDOUT, APP/TASK/deploy)#
Detection of server version failed; root cause: No authentication method found (STDOUT, APP/TASK/deploy)#

I have my db to allow connections from all ip addresses I tried to recreate the DB but nothing help. 

I am not sure what part of the setup is wrong since the does not say much.

It looks like the issue is with the tutorial. 

I should not make that change to bookstore-db. The service should be created with the deployment. 

In Step 1 in https://developers.sap.com/tutorials/cp-cap-java-deploy-cf.html
There is information to create database with name bookstore-db which is incorect becouse that name is reserved for hdi container hence my errors. I have created new db with name bookstore-hana-db and all worked. 
When creating the DB in this step it should also be mentioned to use cloud foundry  environment  and NOT other environment so it will be connected correctly. 

In Step 2 in https://developers.sap.com/tutorials/cp-cap-java-deploy-cf.html 
It should be additional change to the configuration auto-config.enabled  should be set to true otherwise h2 will be used as DB not hana. 

In Step 7 in point 4
There is incorrect url for odata odata/v4/catalog/Books  the correct one should be odata/v4/BooksService/Books to test the solution. It important since if someone did not enabled the web application will not be able to test it. 

After all that it started to work fine.

Thanks Sebastian!
I couldn't reproduce your third point with auto-config but for the other points I improved the tutorial: Better description for hana creation, fix URL by renejeglinsky · Pull Request #23760 · sap-tutorials...
