Adrian, Can you provide a full stack trace of the exception please? It is very difficult to identify where the problem is without that information. An example spreadsheet and a sample of your code that causes the exception would be useful too.
Also note that a NullPointerException is unlikely to be related to memory issues so no need to get more memory for your server yet :-) Bruno 2009/10/9 Adrian Butnaru <[email protected]>: > I made a mistake I use version 3.5 (poi-3.5-FINAL-2009.09.28.jar) not 2.5. > Excuses! > > On Fri, Oct 9, 2009 at 9:11 AM, Adrian Butnaru <[email protected]> wrote: >> POI version is 2.5 in both cases because I uploaded the war file >> created bu Netbeans completely. >> The XLS files are the same. >> I am trying to identify what happens and If I comment all the lines >> with setCellValue it happens first time I am trying to get the value >> from the cell. >> The differences between development version which works with Netbeans >> in WIndows and the live version which gets errors on my Linux server >> is that I am using tomcat 6 in windows and tomcat 5.5 in linux. >> Another issue may be the fact that the server is actually a virtual >> server 512 MB RAM and not a real server.
