I am stuck with an issue with reading .xlsx file. Some temporary files with random name are created under /tmp/poifiles directory whenever I use WorkbookFactory.create(inputStream);. This directory is created with RW-R-R- permission for the first user. So another user on the same machine when tries to access these files, he CANNOT.

Please suggest me any way

1) How can I create these temp files under /tmp directory and not always in /tmp/poifiles (I am using RHEL V5.0)

2) and how can I configure POI such as to change the location from where it reads the temporary files??

Anymore help to solve my problem of different users accessing same .xlsx files through POI is badly needed.
