Hiding password in fisql and bsqldb

Hi,

I'm trying to use fisql and bsqldb in a bash script and I'm having
problems finding a way to hide the password from the ps command without
requiring user input.  For sqlplus with Oracle I can do this:

sqlplus username <<EOF
password
select sysdate from dual;
EOF

However that does not work with either fisql or bsqldb.  All other
attempts have also failed.  Any ideas?
