I have a problem related to HttpServletRequest. Somehow it can not be not passed to the called filter with Forward.
When I try to access the fields on request and the session of the request I get null pointer exception.
Here is the code: As you can see I am printing the content of the session just before forwarding the request. And all the fields that I put in it is there. I see it in logs.
HttpServletRequest reqServ = (HttpServletRequest)request;
Enumeration sessionKeys = reqServ.getSession().getAttributeNames();
while (sessionKeys.hasMoreElements())
{
String key = (String)sessionKeys.nextElement();
System.out.println(key + ": " + reqServ.getSession().getValue(key) + "<br>");
}
request.getRequestDispatcher("/jsp/XXXXX.jsp").forward(request, response);
request in this forward is fully filled and not empty. But the filter which takes affect when /jsp/XXXXX.do is getting a totally empty request object and session containes only a LOCALE param.
Cause of that I can not get the params that I need to use and when I try it gives me a null pointer exception.
Here is struts-config.xml for XXXXX.jsp
<action name="XXXXXFormBean" path="/XXXXX" scope="request" type="com.AAAAAA.service.actions.XXXXXAction"
input="/jsp/XXXXX.jsp">
<forward name="oneself" path="/jsp/XXXXX.jsp"></forward>
<forward name="XXXXX" path="/jsp/XXXXX.jsp"></forward>
</action>
I have searched for such an issue on internet and got nothing.
I am using JBoss EAP 6.4
Struts 1.3.8
Java 1.7
What can I do to solve this issue?
Thank you.
Here is the full error message with trace I got.

This project was written like 13 years ago and at that time that thought that changing the JSESSIONID manally is a good thing to do in WebSphere and it does not create an issues with that. But with JBoss EAP 6.4 it is creating an issue. I have changed the JSSESIONID code to not changing it and all worked out.
