connecting to oracle 12c multitenant database

My question, using coldfusion 11 enterprise datasource gui,

how do you connect to oracle 12c multitenant database,

when you need to log into a pluggable database, beneath

the container database?

What's the connection string, or is it even possible to connect(?) because earlier versions of oracle

didn't use multitenant architecture, you just make a user/password,

grant connect privileges, and connect.

Using Oracle Linux 6.5 64bit.

This is assuming I can connect to the oracle CDB (container database) and PDB (pluggable database) from the shell using sqlplus.

<!------------------------ I can tsnping the pluggable database name pdb1 ---------------------------------------------->

[oracle@localhost ~]$ tnsping pdb1
