Answer 1

Forward Illegal Reference is a term which comes into picture when an uninitialized non global variable value is assigned to a global variable.

In your case Workbook wb = wb.getWorkbook(new File("----")); - wb is uninitialized before calling the getWorkbook() method. For avoiding the FIR you should initialize wb.
