Subject Re: upload fail occasionally
Date Wed, 04 Apr 2007 22:12:43 GMT
Did either of you try specifying the context cleanup
filter?

<filter>
  <filter-name>contextCleanup</filter-name>
  <filter-class>
    org.apache.struts2.dispatcher.ActionContextCleanUp
  </filter-class>
</filter>

and put it first in the filter mapping.

I have yet to have any issues w/ file upload since
including that and I still think I vaguely recall a
thread about this a long time ago but can no longer
find any references to it, so I could be way off-base.
