java.lang.ClassCastException: org.apache.struts2.dispatcher.mapper.ActionMapping

Prasanth Pasala
Hi,

I am trying to forward the request to another action that is present in a different context. It works in struts1 but when trying in struts 2.3.34 I am getting a class cast exception. Both the projects
(contexts) have the same version of struts2.

ServletContext sContext = context.getContext("/context2");
RequestDispatcher rd = sContext.getRequestDispatcher(resource);
rd.forward(request, response);

Thanks,
Prasanth

This usually happens when struts jar is included in application server's lib directory.

... do you try to dispatch request to another Struts application? I
remember e.g. for Tomcat, it uses different classloaders for each app.

I think you can ask and continue with your container (e.g. Tomcat,
Jetty, WebSphere, etc) for a solution.

Regards.

Yes, dispatching request to another struts application. I am using Wildfly which does use different class loaders. Is this issue just with Struts2, as it works with Struts1.

Thanks,

No it's not a Struts issue. You don't see this in Struts1 because maybe
it doesn't use any object bounded to dispatched request. But Struts2
wants to

ActionMapping mapping =
(ActionMapping)request.getAttribute("struts.actionMapping");

A workaround would be removing object with key "struts.actionMapping"
from request before dispatching.

I hope this helps.

Thanks for the prompt response. Tried removing the attribute from the request, but still getting the class cast exception. Is it possible it is being set after I have called the forward?    
request.removeAttribute("struts.actionMapping");     // FORWARD THE REQUEST     ServletContext sContext = context.getContext("/context2");     RequestDispatcher rd =
sContext.getRequestDispatcher("/Login.action");    rd.forward(request, response);    [show/hide original text]

Re: Re: java.lang.ClassCastException: org.apache.struts2.dispatcher.mapper.ActionMapping

It seems like removeAttribute or setAttribute is not getting rid of the attribute from request. See below. If I set the value to a random string then I get a String can't be cast to ActionMapping
exception.

       Enumeration<String> attrs = request.getAttributeNames();
        while(attrs.hasMoreElements()) {
            System.out.println(attrs.nextElement());
        }
        System.out.println(request.getAttribute("struts.actionMapping"));
        request.setAttribute("struts.actionMapping", null);
        System.out.println(request.getAttribute("struts.actionMapping"));

Re: java.lang.ClassCastException: org.apache.struts2.dispatcher.mapper.ActionMapping

Prasanth Pasala
Added the below two lines to my filter (before the struts2 filter) in context2 app. That seems to do the trick. Thought it might create a problem as I am setting a new ActionMapping in the request,
but seems to work fine. Do you see any side effects of this?

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

Thanks,
Prasanth

Could you please register this issue at [1] with title "Support for
cross context request processing" then we will keep it in monitor and
you can track resolution there, thanks for your report!

I'm not sure. But unfortunately I did not know better solution for now
as Struts seems is not ready for cross context request processing :(

It's better to set null instead :
request.setAttribute("struts.actionMapping", null);

works?

Added it to Struts JIRA (WW-4904) If I set the struts.actionMapping attribute to null it still causes the class cast exception. What I have seen is that after setting it to null if you call
getAttribute you would still get the old ActionMapping object, not sure how that is possible. Thanks, Prasanth --------------------------------------------------------------------------- [show/hide
original text]
No it's not a Struts issue. You don't see this in Struts1 because maybe
it doesn't use any object bounded to dispatched request. But Struts2
wants to

ActionMapping mapping =
(ActionMapping)request.getAttribute("struts.actionMapping");

A workaround would be removing object with key "struts.actionMapping"
from request before dispatching.

I hope this helps.

Hmm... so how and why `request.setAttribute("struts.valueStack", null)`
works.

That's weird and so very important to me :)

Could you please see what is the type of request when you receive it in
your second context filter? e.g. println(request.getType()) before those
your two lines (I could see myself but maybe it will be different from
your one!)

Thanks in advance!

Below is the exception you would get if the valueStack is not set to null.

You have two the same JARs on a class path but in different versions
(probably xwork-core-*.jar) or JARs were loaded by different
classloaders which means some framework's JARs were included inside
Wildfly

There are two applications on different contexts. Each have their own struts jars. The exception happens when a request to one context is forwarded to another context.

Thanks,

What do you mean by "forwarded"?

https://issues.apache.org/jira/projects/WW/issues/WW-4904

Forwarded using request dispatcher.

ServletContext sContext = context.getContext("/context2");
RequestDispatcher rd = sContext.getRequestDispatcher(resource);
rd.forward(request, response);
