TokenSessionStoreInterceptor - puting non Serializable objects in the Session
-----------------------------------------------------------------------------
Key: WW-2803
URL: https://issues.apache.org/struts/browse/WW-2803
Project: Struts 2
Issue Type: Bug
Components: Core Interceptors
Affects Versions: 2.0.11
Environment: - CentOS Linux
- Tomcat 6.0.16
- Struts 2.0.11
Reporter: Juliano Carniel
Priority: Critical
I haven't found any issues for this, neither on the mailling lists, so i'm
opening one.
I'm intercepting an Action with the TokenSession Interceptor, it works fine,
but it is saving a non Serializable object
(org.apache.struts2.dispatcher.StrutsRequestWrapper) on the session, so in a
tomcat cluster environment the session cannot be serialized and sent to the
other machine.
The class that is been saved in the session is the below:
org.apache.struts2.util.InvocationSessionStore$InvocationContext on the
"extraContext" attribute inside this class
The DeltaManager is complaning about StrutsRequestWrapper, and indeed it is not
serializable. Could it be made Serializable? Or it is not suposed to be?
There's a full stackTrace:

SEVERE: Unable to serialize delta request for sessionid
