Subject [jira] [Updated] (WW-4904) Support for cross context request processing
Date Mon, 18 Dec 2017 17:02:00 GMT

     [ https://issues.apache.org/jira/browse/WW-4904?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Prasanth  updated WW-4904:
--------------------------
    Description: 
When a request is forwarded from one context to another (both using struts2) you get a ClassCastException.
Both the projects has their own struts jars (in WEB-INF/lib folder).

To make it work you have to have a filter (before struts2 filter) in the application that
is receiving the request and have the below two lines. 

request.setAttribute("struts.actionMapping", new ActionMapping());
request.setAttribute("struts.valueStack", null);

Caused by: java.lang.ClassCastException: org.apache.struts2.dispatcher.mapper.ActionMapping
cannot be cast to org.apache.struts2.dispatcher.mapper.ActionMapping
