Hi,

AFAIK, there is no builtin way to do this in jinterface. You have
several options:
- implement a name registry yourself in Java and use it to retrieve the pid,
- let the mailbox answer to a message of 'whats_your_pid_dude' (or
whatever :-) with the right value
- when creating the mailbox, send the pid to some process on the erlang side

Vlad
