Java java.sql.SQLException: Invalid column index on preparing statement

Question

my code below query the database for a set of rows based on user input. I have tried and tested the query inside of SQL Developer and it works perfectly fine returning the correct rows. And example of an input is : 2013-01-22

But for some reason inside of java i am getting this error:

java.sql.SQLException: Invalid column index

The console indicates it is firing at this line here:

preparedStatement.setString(1, to);

The full connection code:

ResultSet rs = null;
        PreparedStatement preparedStatement = null;
        try {
            String strQuery =
                    "SELECT homes.home_id, homes.title, homes.description, homes.living_room_count, homes.bedroom_count, homes.bathroom_count, homes.price, homes.sqft,"
                    + " listagg(features.feature_name, '\n') WITHIN GROUP(ORDER BY features.feature_name) features, home_type.type_name"
                    + " FROM homes"
                    + " INNER JOIN bookings ON bookings.home_id <> homes.home_id"
                    + " INNER JOIN home_feature ON homes.home_id = home_feature.home_id"
                    + " INNER JOIN home_type ON home_type.type_code = homes.type_code"
                    + " INNER JOIN features ON home_feature.feature_id = features.feature_id"
                    + " WHERE bookings.booking_end < date '?'"
                    + " OR bookings.booking_start > date '?'"
                    + " GROUP BY homes.home_id, homes.title, homes.description, homes.living_room_count, homes.bedroom_count, homes.bathroom_count, homes.price, homes.sqft, home_type.type_name";

            preparedStatement = conn.prepareStatement(strQuery);//prepare the statement
            preparedStatement.setString(1, to);//insert
            preparedStatement.setString(2, from);//insert
            rs = preparedStatement.executeQuery();//execute query

The full stack trace looks like this:

Im not quite sure why the error would be thrown as the query works fine is SQL developer. I am using Oracle

EDIT:

The result set is read into this within the same method. The homes object is then passed back:

HomeList homes = new HomeList();
homes = new HomeList(rs);

The constructor looks like this:

public HomeList(ResultSet rs) {
    this();
    try {
        while (rs.next()) {
               list.add(new Home(rs.getInt(1),   
                                 rs.getString(2),
                                 rs.getString(3),   
                                 rs.getInt(4),
                                 rs.getInt(5),
                                 rs.getInt(6),
                                 rs.getInt(7),
                                 rs.getInt(8),
                                 rs.getString(9),
                                 rs.getString(10)
                                     ));
        }//end while
    } catch (SQLException e) {
        e.printStackTrace();
    }//end try
}

Answer 1

Everywhere inside the query string, the wildcard should be ? instead of '?'. That should solve the problem.

EDIT :

To add to that, you need to change date '?' to to_date(?, 'yyyy-mm-dd'). Please try that and let me know.

Answer 2

As @TechSpellBound suggested remove the quotes around the ? signs. Then add a space character at the end of each row in your concatenated string. Otherwise the entire query will be sent as (using only part of it as an example) : .... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....

The ? and the OR needs to be seperated by a space character. Do it wherever needed in the query string.
