How do we fix it?

We need to use Spring security with urlrewrite, so this works by having those dispatcher tag. If we comment out the tag, jboss does not complain:

<servlet-mapping>

  <servlet-name>CrudServlet</servlet-name>

  <url-pattern>/ws/crud</url-pattern>

  <!--

  <dispatcher>FORWARD</dispatcher>

  <dispatcher>REQUEST</dispatcher>

  <dispatcher>INCLUDE</dispatcher>

  -->

</servlet-mapping>

How to make it work with both GAEJ and Wildfly?

Thanks so much!
