Issues in Reading from Excel file

I do have red x in front of my project explorer[/color]


This is my code:


public class Reading_XLS_Files {

public static void main(String[] args) {
// TODO Auto-generated method stub

Xls_Reader datatable = new Xls_Reader ("C:\\Users\\Sailalitha\\Desktop\\DataToRead");
datatable.getRowCount("Record");


}

}


This is what Sam also having trouble with:
I am getting the following error:

java.io.FileNotFoundException: C:\Users\Sailalitha\Desktop\DataToRead (The system cannot find the file specified)
