Hi all,

I have the following problem. I try to open excel files that I received by 
email. I can't open some with POI. But I can open them with Excel 97. They 
aren't protected by a password.
I get the following exception with the HSSF class:

I tried to read them with BiffViewer and I also got an error:

        at org.apache.poi.hssf.dev.BiffViewer.main(BiffViewer.java:649)

I searched on internet and didn't find any solution.
I hope someone will have an idea.

Thanks

Regards
