Create Kafka connect without confluent - windows

Question

I recently started with Kafka and I try to create a Kafka connect to connect to oracle but I can't do it. The information I found is about confluent, but that does't work in Windows ... How can i configure one or create it with java?
I use for my test standalone conecction:
cmd .\windows\connect-standalone.bat .\config\connect-standalone.properties .\config\connect-bbdd.properties ->
name=jdbc-conector
connector.class=io.confluent.connect.jdbc.JdbcSourceConnector
tasks.max=1
connection.url=dbc:oracle:thin#localhost:xe
connection.user: user
connection.password: pwd
mode = bulk
topic.prefix=test
table.whitelist: mytable
Error:

Answer 1

The confluent command doesn't work natively in Windows, no.
But connect-distributed or connect-standalone are not only in Confluent, and should both work and load the JDBC connectors provided within Confluent Platform if you did download it on Windows.
Otherwise, if you have only Apache Kafka, you will need to download JDBC Connector separately and set it up yourself via the plugin.path property mentioned in the Connect config files.

Answer 2

This error that you get:
No suitable driver found for jdbc:oracle:thin#localhost:xe
for configuration Couldn't open connection to jdbc:oracle:thin#localhost:xe
is because you've not made the Oracle JDBC driver available. See https://www.confluent.io/blog/kafka-connect-deep-dive-jdbc-source-connector#jdbc-drivers.
