Struts Upload - java.io.WriteAbortedException on DiskFile ??

[Matt Raible <ma...@yahoo.com>]

I keep getting the exception below in my log files after I upload and write a
file to disk.  I'm using code from the struts-upload example.  Could it be that
my application is marked distributed in web.xml or my Form that holds this file
is marked Serializable?

Thanks,

Matt
