Where to download the .jar file?

Best to use a build tool like Maven or Gradle.

https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.16.1

That page has the dependency format for many build tools but also a link to download the jar. If you download 1 jar, you will also need to download all the other dependency jars. Build tools will automatically get all the dependencies for you.
