Derby Embedded get list of all tables

Question

I am writing a small program that uses derby embedded to store schedules for teachers. Each teacher will have their own table and I want to use the teacher name for the table name and allow the teacher to be selected from the combo box. I have an SQL statement i'd to have return all the current tables, but i think i am doing something wrong:
public static String[] getTeacherNames() {
        String[] tableNames = null;
        String tableFind = "select APP.schemaname || '.' || Schedule.tablename"+
                             "from sys.systables Schedule, sys.sysschemas APP"+
                             "where Schedule.schemaid = APP.schemaid"+
                                  "and Schedule.tabletype = 'T'"+
                             "order by APP.schemaname, Schedule.tablename";
        String protocol = "jdbc:derby:";
        String dB = "Schedule";
        Connection con;
        Statement stmt;
try {
                con = DriverManager.getConnection(protocol + dB +
                        ";create=true", "app", "app");
                stmt = con.createStatement();                                   
                ResultSet rs = stmt.executeQuery(tableFind);
                ResultSetMetaData rsmd = rs.getMetaData();
                int rowCount = 0;
                while (rs.next()) {
                        tableNames[rowCount] = rs.getNString(rowCount);                      
                        rowCount++;
                stmt.close();
                con.close();
            } catch(SQLException ex) {
                    System.err.print("SQLException: ");
                    System.err.println(ex.getMessage());
            return tableNames;                
    }can anyone help, or have any better ideas? I modified the statement from the one i found on the derby Wiki.

Answer 1

like this?
String[] getNamesArray = {"%"};
        String[] tableNames[] = null;
        String protocol = "jdbc:derby:";
        String dB = "Schedule";
        Connection con;
        Statement stmt;
try {
                con = DriverManager.getConnection(protocol + dB +
                        ";create=true", "app", "app");
                DatabaseMetaData dbmd = con.getMetaData();
               tableNames = dbmd.getTables("%");                   
                con.close();
     } catch(SQLException ex) {
            System.err.print("SQLException: ");
            System.err.println(ex.getMessage());
            return tableNames;                
    }the DatabaseMetaData will only except the names of tables I already know? I've been messing with it for a while and can't seem to get it to be happy with what I am giving it.
