It is a general limitation of SSL.  To be strict: you can only have one 
certificate per *endpoint*, that is, IP address/port combination.

The reason is that the negotiation of the encrypted connection is done *before* 
the host header is sent.  Therefore the server has to deduce which certificate 
to send without knowing which Web site the client wishes to access.  Therefore 
the server always sends the one certificate that you have associated with that 
endpoint.

If you don't mind URLs of the form https://myserver.example:8443/somepage then 
you can have multiple certificates per IP address, and indeed per Tomcat.  But 
the sites need to be served on different ports.
