------------------------------------------------------------

Thank you for your recommend.
We changed web.xml and source code as your comment. (Changed to Servlets 2.5)
But problem still happens sometime as we restart Webshpere Application Server.

Please provider us somehow to trace how object transform from web-from data to action \
data.

> Hi Lukasz Lenart ,
> We are using struts-portlet framework in Websphere Portal server clustering ( 1 \
> Deploy Manager and 4 Portal servers instances) in production.  Currently there is \
> one issue happen in one of 4 servers randomly.  The exception is showing login form \
> in set Property is null in one server, but at that time other 3 servers are working \
> fine. This issue can happen in any one of 4 servers  in our production environment. \
> We have also raised few PMR  to  IBM team for this issue. But IBM  said it is not \
> caused by them.  We need your help to check if any possible way to cause this issue \
> in struts.   If possible, pls share us your avaliable timing and contact, we would \
> like to have a call with you and IBM support to identify root cause.  
> ===IBM response=============
> When I refer the past PMR ( 18484,000,834)  we shared on all the findings and \
> waiting for your Application team feedback,  as such I don't think any  further \
> action pending on  IBM Support end. do check with Application team and  can we ask \
> Application team not using  the code what Application team using is  not an IBM  \
> API / service code "                          \
> com.opensymphony.xwork2.util.logging.commons.CommonsLogger" , good to    check with \
> Application team to discuss with respective vender.  
> The  above error code from strut's application code, check with Application support \
> and ask them to explore further.  As  I hope we all are in same page now, as  PMR \
