cannot connect to firebird when restarted using Runtime.exec

[bradly smith]

Good day every1 i'm new to the site, i'm have a serious problem:

I start the inetd daemon using Runtime.exec, i'm sure it starts because when i exit my java program and start again i can connect. However when i start inetd from inside my application i cannot connect using java.sql.Connection, i have to close the app and start again....Can someone please help me!!! (by the way i'm using Ubuntu 9.0 server

here is the code to start the process :
Process p = Runtime.getRuntime().exec("sudo /usr/sbin/inetd"));
p.waitFor();
connection = DriverManager.getConnection(url, user, password);

it says:

org.firebirdsql.jdbc.FBSQLException: GDS Exception. 335544721. Unable to complete network request to host "ip address".
Reason: Unable to complete network request to host "ip address".
