Logstash cannot connect to Oracle cloud using wallet key

Hello community,
I'm having hard time to establish Logstash connection towards Oracle cloud autonomous db. I have suspicion that it is connected to wallet key.

I was able to connect to Oracle cloud using Ubuntu/sql developer either using "cloud wallet" connection type but also using "custom jdbc". I have used following form:
jdbc:oracle:thin:@banach001_high?TNS_ADMIN=/home/otomar-jupiter/ora.cloud/wallet_keys/Wallet_banach001

Therefore I thought I can use same string in Logstash config, but it seems it doesn't work. Just for info, I have tried ojdbc7/8/10.jar, neither of them worked.

Here is the config detail:

    jdbc {
#==========| JDBC Configs |==============#
        jdbc_driver_library => "/home/otomar-jupiter/ora.cloud/jdk/ojdbc8.jar"
        jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
        jdbc_connection_string => "jdbc:oracle:thin:@banach001_high?TNS_ADMIN=/home/otomar-jupiter/ora.cloud/wallet_keys/Wallet_banach001"
      # jdbc_default_timezone => "Europe/Zurich"
        plugin_timezone => "local"
	  # jdbc_page_size => 1000000
#==========| Database Details |==========#

In logstash log, I see just this java error:

[2020-09-09T21:01:46,952][ERROR][logstash.javapipeline    ][banach-prod-onln-upc][b27d9c2a6c018ecf07741dbf4bfd050c8559f9e3e21cb687908c57f4fc994d85] A plugin had an unrecoverable error. Will restart this plugin.

I would be happy for any suggestions or help.

Ok, it seems I have sort it our myself :smile:
If anybody would benefit, here is the solution
jdbc_driver_library => "/home/otomar-jupiter/ora.cloud/jdk/ojdbc10.jar,/home/otomar-jupiter/ora.cloud/jdk/ucp.jar,/home/otomar-jupiter/ora.cloud/jdk/osdt_core.jar,/home/otomar-jupiter/ora.cloud/jdk/oraclepki.jar,/home/otomar-jupiter/ora.cloud/jdk/osdt_cert.jar"

Additional files needed for Oracle wallet. Oracle docs for reference.
