@lepistane Depending on what your "url/db" value actually is, that simply won't work.

If all you have is a JDBC connection string -- you have to use it as-is, you can't use a hash map for the spec.

The whole point of the hash map is to use something simpler than the string and simpler than the whole classname / subname / subprotocol stuff.

{:dbtype "postgres" :dbname "db" :user "usr" :password "psw"}

You're really not going to be able to get much more specific help from us unless you share the actual JDBC connection string you're trying to use -- with the user / password values changed to protect your secrets of course 🙂
