Question

I created a java db database using netbeans 7 services, I used the java embedded driver to connect to the java db.
I can find my database under the connection in the java database, under a schema called ROOT.

This is my java db connection name:

jdbc:derby:AddressBook [root on ROOT]

But, when i try to use that schema in my project i get an exception that states

Caused by: ERROR 42Y07: Schema 'ROOT' does not exist
    at org.apache.derby.iapi.error.StandardException.newException(Unknown Source)
    at org.apache.derby.impl.sql.catalog.DataDictionaryImpl.getSchemaDescriptor(Unknown Source)
                       .....

The error apears in the select statement. what should i do to make it readable in the project?

This is my code:

private static final String URL = "jdbc:derby:AddressBook";
   private static final String USERNAME = "root";
   private static final String PASSWORD = "cs101";

   private Connection connection = null; // manages connection
   private PreparedStatement selectAllPeople = null; 
   private PreparedStatement selectPeopleByLastName = null; 
   private PreparedStatement insertNewPerson = null; 

   // constructor
   public PersonQueries()
   {
      try 
      {
         connection = 
            DriverManager.getConnection( URL, USERNAME, PASSWORD );

         // create query that selects all entries in the AddressBook
         selectAllPeople = 
            connection.prepareStatement( "SELECT * FROM ROOT.Addresses" )

Answer 1

Try putting this code before creating the connection

Class.forName("org.apache.derby.jdbc.ClientDriver")
