-----------------------------
Hi Team,
I am also facing same kind of issue as mentioned above.
Recently we have upgraded to struts2-core-2.3.32.jar version from
struts2-core-2.3.20.jar. As part of this upgrade, we have replaced/added below
dependency jars
struts2-javatemplates-plugin-2.3.32.jar
struts2-core-2.3.32.jar
asm-3.3.jar
xwork-core-2.3.32.jar
asm-commons-3.3.jar
asm-tree-3.3.jar
freemarker-2.3.22.jar
javassist-3.11.0.GA.jar
ognl-3.0.19.jar
commons-fileupload-1.3.2.jar
commons-io-2.2.jar
commons-lang3-3.2.jar
xwork-core-2.3.32.jar
In certain screens, request parameter values are not available in actions.
>From JSP passing value as ,
eSignatureVO.esignAck :"true" - [eSignatureVO as Object and esignAck as
attribute inside]
we are able to see the values in parametersInterceptors (DEBUG mode). When
execution reaches OgnlRuntime.java class (getGetMethod())
public static Method getGetMethod(OgnlContext context, Class targetClass,
String propertyName) throws IntrospectionException, OgnlException {
// Cache is a map in two levels, so we provide two keys (see comments
in ClassPropertyMethodCache below)
Method method = cacheGetMethod.get(targetClass, propertyName);
if (method != null)
return method;
cacheGetMethod return (eSignatureVO for propertyName) as
eSignatureVO=java.lang.reflect.Method
ognl.OgnlRuntime$ClassPropertyMethodCache.get(java.lang.Class,java.lang.String).
So values are not set into action variables . Please help us here.
We are able to replicate this in our lower environment.
Note : we are not facing this across application. Only on certain screens, we
are facing this issue.
Please help us to resolve the same.

> 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

>
> 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.
