ClassNotFoundException when trying to deconfig Oracle Enterprise Manager

Question

The Enterprise Manager for my Oracle 11.2 installation doesn't work anymore as described in How can I change the connection descriptor used by Oracle Enterprise Manager? and I tried to re-configure it using the instructions here. However, the deconfig command runs into a ClassNotFoundException:

C:\Users\bcalmac>emca -deconfig dbcontrol db -repos drop

In what jar is this class, so I can copy it over from another Oracle installation?
