Invalid header reading xls file

Question

I am reading one excel file on my local system. I am using POI jar Version 3.7, but getting error Invalid header signature; read -2300849302551019537 or in Hex 0xE011BDBFEF

Answer 1

Just an idee, if you using maven make sure in the resource tag filtering is set to false. Otherwise maven tends to corrupt xls files in the copying phase
