Thread: Problem with connecting to DataBase

Hi
I'm trying to connect to database with jdbc in netbeans.
I use this code :

    String host = "jdbc:derby://localhost:1527/MIRDataBase [mir on MIR]";
            String name = "mir";
            String pass = "mir" ; 
            con = DriverManager.getConnection( host, name ,pass );

as you see I set username and password but I get this error :

Jan 07, 2013 4:02:19 PM DataBase.Crawler_DataBase <init>

I've attached my db properties
Does anybody know what's wrong with my connection ?
Thank you

My problem solved but I want to explain about solution. it might helped someone
problem was about apache setting. I add apache to server in service tab in netbeans and edit it's xml setting file (tomcat-users.xml) and add more access to my user with proper username and password :
roles="manager-gui,manager-script,manager-jmx,admin"
it's working now
and one more point. if you want to create an application which has access to database you may add something like this :
permission java.net.SocketPermission "127.0.0.1:1527", "connect, resolve";
to .java.policy file

by the way thank you java forum
