[seam-issues] [JBoss JIRA] Commented: (SEAMSERVLET-42) Seam Servlet broken in multi-war ear deployment

Seam Servlet broken in multi-war ear deployment ----------------------------------------------- Key: SEAMSERVLET-42 URL: https://issues.jboss.org/browse/SEAMSERVLET-42 Project: Seam Servlet Issue Type: Bug Affects Versions: 3.0.0.Final Reporter: Jozef Hartinger Fix For: 3.0.1.Beta1 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: 15:14:42,467 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC00001: Failed to start service jboss.deployment.unit."test.ear".WeldService: org.jboss.msc.service.StartException in service jboss.deployment.unit."test.ear".WeldService: org.jboss.weld.exceptions.DeploymentException: WELD-001409 Ambiguous dependencies for type [HttpServletRequest] with qualifiers [@Default] at injection point [[field] @Inject private org.jboss.seam.servlet.http.CookieParamProducer.request].
