I use maven just to handle de dependencies but without m2eclipse. In my EAR project I have an application.xml file as follows: <?xml version="1.0" encoding="UTF-8"?> <application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:application="http://java.sun.com/xml/ns/javaee/application_5.x... xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd" version="5">   <description>Xstreamline ear project</description>   <display-name>xstreamline3-ear</display-name>   <module>     <ejb>jboss-seam-2.2.1.Final.jar</ejb>   </module>   <module>     <web>       <web-uri>xstreamline3-3.1.1.war</web-uri>       <context-root>/</context-root>     </web>   </module>   <library-directory>/lib</library-directory> </application> When I add the server and publish the application, I get: 1) Two copies of jboss-seam-2.2.1.Final.jar, one is at the main level of the EAR, and the other is inside the WAR file (xstreamline3-3.1.1.war/jboss-seam-2.2.1.Final.jar) 2) The default auto-generated application.xml, under main/application/META-INF/, besides my own application.xml under the root EAR folder/META-INF When I run the server from Eclipse it starts OK, but when I enter the application I get the following error: ERROR [Exceptions] handled and logged exception java.lang.IllegalStateException: No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed) If I remove one of the jboss-seam-2.2.1.Final.jar under the WAR file it DOESN'T work. It ONLY WORKS if I only remove the other jboss-seam-2.2.1.Final.jar (which is in the root EAR folder) and I changed the ejb module declaration in my application xml as follows: <module>     <ejb>xstreamline3-3.1.1.war/jboss-seam-2.2.1.Final.jar</ejb>   </module> I don't understand why  this is happening: Why the plugin is copying one jboss-seam-2.2.1.Final.jar under the WAR file? And why only works if I leave the file there and not in the EAR root? What should I do with the auto-generated application.xml ? Please help me with this. I have read too differents posts about the auto-genereated application.xml but I couldn't find a clear explanation about it. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/607270#607270] Start a new discussion in JBoss Tools at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
