Can I use Weblogic and Oracle XE as a local desktop for free when developing a commercial product?

Question

Java

Oracle XE as a DB (license www.oracle.com/technetwork/licenses/database-11g-e ...
server Free Oracle WebLogic Server 12c (12.1.2) (license www.oracle.com/technetwork/licenses/wls-dev-licens...
The licenses are a little unclear.

Answer 1

For development and testing (and self-learning, for example), you can use any paid versions of Oracle products. Though Oracle DB Enterprise Edition. Nobody will say a word to you.
