Jason Porter commented on SOLDER-248:
-------------------------------------

It sounds like this is spec related and really nothing we can do that will be portable, is that correct?

> The Servlet specification requires a java library to be bundled within the WEB-INF/lib folder for its web-fragment.xml to be read. Therefore, if multiple web applications using Seam Servlet are bundled within an EAR, they all have to package Seam Servlet within their WEB-INF/lib folders.
> The CDI specification is not clear in defining the application scope in an EAR (See https://issues.jboss.org/browse/CDI-129 for details.)
> JBoss AS 7 implements the application scope as per-ear.
> This results in conflicts between multiple instances of Seam Servlet. Therefore, when the ear is deployed, the deployment fails with AmbiguousResolutionException like the following one:
