That is my problem: No it doesn't.

PingObjectImpl extends an automatically generated CORBA file called
_PingObjectImplBase which just seems to have a blank constructor.

Maybe a CORBA specialist can guess what the author of this tutorial
meant by doing this?
Maybe I am not generating the correct versions of the files from the
idl file?

Here is the content of the generated file _PingObjectImplBase.java:

package PPModule;

/**
