Schema name in Java EE app server datasource configuration?

Hello,

I'm trying to configure a PostgreSQL data source at WebSphere Application
Server.

I defined a custom JDBC provider type and data source based on the following
description: https://jdbc.postgresql.org/documentation/head/ds-cpds.html

Now I need to specify a schema name in addition to all of that, but that
isn't documented there. I know there's a connection property currentSchema,
however is it possible to configure it for the JEE data source? I may try
some trial & error attempts to configure it somehow, but perhaps you know
how to do it properly right from the start?

And in such case it would be useful to add it to the documentation.

Best regards.

Petr
