Hi Matthias, U may try event based POI APIs to read the large excel sheet. Though its not as simple as user model APIs but takes less memory.

The options "-Xms -Xmx" are intended to be supplied with actual memory values. Specifying "-Xmx" by itself doesn't do any good. You might try "-Xmx1024m". > -----Original Message----- > From: Matthias Knapp [mailto:[EMAIL PROTECTED] > Sent: Tuesday, March 27, 2007 2:54 AM > To: poi-user@jakarta.apache.org > Subject: How to read just one sheet out of a large excel file? > > Hi, > > I´d like to read and write within an existing excel file (10 > MB) via HSSF, but I always encounter an OutOfMemoryError (not enough > heap space).
