Hi Forum , 
 
I am facing a problem with the xls file reading using POI apis' the problem
arises when I get a nely generated file from unix system generated through
soem perl script.
With some data that I need to upload and read using POI api 
 
For the first time when I get the xls file in the form of a zip file I
extract it  into some directory, now I try to read this file usig POI apis 
I get java.io.IOException: block[ 0 ] already removed & hence
java.lang.IllegalStateException: The Workbook reader object is null.
 
as a result of it the file is not read . 
 
Now I open the file and just do a save the file is read properly  can anyone
please tell me what  can the problem , 
 
Getting following log during nascent read.
