I've previously tried with these and re-tried per your
recommendations, until I pasted the erroneous code above:
"jdbc.firebirdsql:localhost/3050:d:/javadev/databases/muratest.gdb"
"localhost/3050:D:/Javadev/Databases/MURATEST.GDB"
"jdbc:firebirdsql://localhost:3050/d:/JavaDev/Databases/muratest.gdb"

I was still not able to get a connection..I've double checked that
such a database exists in the drive and directory..was able to connect
to it via IBManager. Still am not able to figure out why this does not
work. I've also turned off all firewalls for just in case.
