Of course it is. RequestDispatcher.forward() is just an API call -
it's not a language construct - how could it stop the rest of the code
from executing.
Think of it as a normal method call: the executiopn branches to the
specified servlet and when that servlet completes control returns to
the point where it was called.
Therefore the rest of the calling servlet is executed.

What does the spec say on this? I think you'll find it says that you
can't if the servlet you forward to writes to the OS.

If the jsp files is actually sending anything then the behaviour of
your servlet container here is illegal. It MUST NOT allow a write to
the OS after a write has already taken place.
