Could not get a db connection

Question

I need some help!!
I can't connect to my db!! When i run my code, it triggers an Exception
called "Problem getting connection: could not get a db connection!". If someone know anything about it, please help me.
Thanks in advance...
Here is how my code looks like:
import java.sql.*;
import javax.sql.*;
class testejdbc
public static void main(String []args) throws Exception
Class.forName("org.firebirdsql.jdbc.FBDriver");
String url = new String("jdbc:firebirdsql:mydatasource");          
Connection con = DriverManager.getConnection(url, "mydba", "mypass");

Hi,
Basically, the url should be follow a form depending on
different driver. and the form would be very resticted.
The best idea is to reference the docuement accompanying
with the driver. If the form is not correct, the connection
information that driver need may not be sufficient for
you. If you are sure that the url that you write is ok,
and check if you have the correct set up for the database.
wrong database name, database server port, address.
sometimes, the database server would have the restrict on
the connection number. If the request is over the the max
connection number, the connection might be rejected. It
depends on the database server, jdbc driver.(both of them
may have such a constraint.).
good luck,
