> Key: WW-4310
> URL: https://issues.apache.org/jira/browse/WW-4310
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors, Expression Language, Integration
> Affects Versions: 2.3.15.1
> Environment: IBM AIX 6.1.0.0
> Websphere Application server 7.0.0.21
> Websphere Portal server 7.0.0.2
> Reporter: chenlin
> Fix For: Future
>
>
> 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 20364,000,834 & PMR
> 18184,000,834 - findings Pointing same struts2 loging function, even
> application team explore why they enabled this log ? ,how this impacted the
> Application Interface page with user login error.
