thank you for answer...
Did you try to a full publish ? (right click on the server, click Full Publish) ?
<----yes ,I did. use full publish always.
is the web.xml actually in the project ? JavaEE 6 does not require a web.xml anymore.
<-------yes. when i use [mvn jboss-as:deploy] , the web.xml is in the content.
best regards!
