Help with maximum size of HSSF file

[M�guel �ngel Mulero Mart�nez]

I'm trying to create a Excel file with POI. I want to create a file with
25000 rows aprox, but I recive an "OutOfMemory" java Exception. I know that
Excel supports 65535 rows. What's the maximum limit of POI-HSSF? Is there
some way to change this?

Thanks to all!!
