> create database 'javatest.gdb';

Use a fully qualified path and include username and password
parameters in the create database statement. Consult the docs on the
subject of connection string and creating databases. If you do not
have the docs, look in the Group Database area (New-User Links) to
locate them.

Also, I'd recommend against using IBAccess. I found it to be a very
rudimetary tool at best -- and why use something basic when you have
excellent, free, all-in-one FB/IB tools like IBExpert personal
edition and IB_SQL at your disposal.
