Error in creating and reading excel file

file name seems wrong [color=#FF0000:2yjlny40]test.xlsx.xls[/color:2yjlny40]

I dont think the file name should have any concerns here because its just as good as any other name like abc.xyz.xls.
However, I tried changing the file name and the file name in the code as well. But its giving the same error.

Hoping for Ashish to look into. I am sure, he will need no time to give a solution for this.
I tried googling but no solution I got. Requesting to please help out on this. The changed code looks like;

public class TestRedingfromxls {

public static void main(String[] args) throws IOException {




File First_File=new File("D:\\Temp\\test.xls");
Workbook wb=new WorkbookFactory.create(inp);

have you tried using xls_reader.java?

No, I have not tried with xls_Reader as I wanted to understand that in depth.

The intention is that if I use XLS_Reader, I may not be able to answer interview question as I use the ready-made methods written in XLS_Reader.
Please help me in understanding it in the best way so that i am able to answer for Interview questions like how do your read data from your xls in your data driven framework.

try this.
