I am getting error in these two packages

import org.apache.poi.poifs.filesystem.*;

import org.apache.poi.hpsf.DocumentSummaryInformation;

The type org.apache.poi.poifs.filesystem.POIFSFileSystem cannot be resolved. It is indirectly referenced from required .class files

I have attached a snapshot my java build path…since the program require

poi-scratchpad-3.2-FINAL-20081019.jar

It is correctly set in java build path..then why I am getting such error ..help..!!
