can see my db in Java DB

[vitaly87]

Hello all!
I am using java with netbeans.
I am using derby drive.
I cant see my db that I creats with this method:

      Class.forName("org.apache.derby.jdbc.EmbeddedDriver");
       con = DriverManager.getConnection("jdbc:derby:"+getDBSystemDir()+";create=true;user=demo;password=demo");
   con.commit();

All works fine from the code and from that code I can get all the tables but I cant see my db in Services->Databases->Java DB

thanks for helping
