A couple of people pinged me to ask if it was possible to do a "Step-into" from a Java class into a PL/SQL stored procedure while debugging.

The trick is to use two debug sessions - one to remote debug the PL/SQL and the other to debug the Java file.
Here is a little demo and explanation of the setup to get this working.
