I have this application running on JBoss 4.0.5.GA. Big picture is: an input file is split into certain blocks, those blocks are given certain order and are re-combined to form a file again. Then an executable is run on them and results are generated. These results are displayed on a file, and a list is provided to the user to download. If not, the next step would zip those files and send an email to the user as an attachment and then delete the files on the server. Problem: it works fine, however, with larger files (1GB), it displays the files to download, but on the next step I am getting this error message:
I have checked the log file ( i am using log4j ), and it is showing this error:
I am suspecting it is happneing becuase of session time out, because it is running fine with the smaller files. Can I get some help here ? If I need to post my code here or if I need to explain more, please let me know. Thanks

Not sure whether this is a session timeout issue. As per the logs, while deleting the files on the server, null is being passed to the Integer.parseInt method, which is causing this NumberFormatException. You might have to check why the null is being passed to that method.
Anyways, if you are interested in knowing how to disable session timeout - By default the session timeout is 30 minutes for all the web applications deployed on JBoss. In order to override this value, you can add the following element in the web.xml file of your application:
The session-timeout value is in minutes. As per the web.xml dtd
If the timeout is 0 or less, the container ensures the default behaviour of sessions is never to time out.

here is my send_del() method:
and here is my send mail method:
Can anyone help me figure out the problem ? log file also suggest : illegal address, and then produces the error listed above. I fail to understand, how is running fine with smaller input files and not with larger files. I have tried using negative session time out time, it works but now it is sending an email with the result.zip (the size of the file is not right). I can see the size as 109KB on the server, but the attached result.zip is just 9KB. Someone, please help. Thanks [ July 04, 2007: Message edited by: Nasir Munir ]
