In shell you just export

export ISC_USER=SYSDBA
export ISC_PASSWORD=masterkey

and in Java you use:

String user = System.getenv("ISC_USER");
String password = System.getenv("ISC_PASSWORD");

if (user == null || password == null)
throw new MyException("Either user name or password is not set.");

java.sql.Connection connection =
java.sql.DriverManager.getConnection(
"jdbc:firebirdsql:192.168.0.115/3050:/database.fdb",
user,
password
);
