[undertow-dev] IllegalArgumentException - 'No servlet context to dispatch to' error in undertow for async servlet

[Dhamodharan Devarajan]

Hello,

I am getting the below error when undertow tries to dispatch the
httpresponse.

     java.lang.IllegalArgumentException: UT010046: No servlet context at
 to dispatch to

I am using Jetty.Continuation (8.1.3) to suspend the HTTPrequest until it
has the response. I have spring (3.2.9) application that is deployed in
wildfly (8.2.0.Final). Spring servlet is configured via web-fragment.xml to
indicate that servlet is asynchronous

    <servlet>
        <servlet-name>apis</servlet-name>

<servlet-class>com.xyz.xyzapp.server.common.spring.ClassloaderOverridingDispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        <async-supported>true</async-supported>
    </servlet>

When one of the job (job is internal framework) completes, it need to
respond back to clients (whoever is listening)
that job is completed. During this workflow, I am getting the above error.

I made sure the wildfly is up and running, clients are actually waiting for
response.

This was working with Jboss 6.1.0.Final/Tomcat.

What could be the problem? Any configuration I need to add in
standalone-full.xml for undertow? It appears that undertow closed the
HTTPrequest, not sure.

Regards,
Dhamodharan
