when a session bean(2.1) is to be deployed , i had given in jboss-ejb3.xml

<?xml version="1.1" encoding="UTF-8"?>

<jboss:ejb-jar xmlns:jboss="http://www.jboss.com/xml/ns/javaee"

               xmlns="http://java.sun.com/xml/ns/javaee"

               impl-version="2.1">

              <enterprise-beans> 

                 <session>                         

                    <ejb-name>SESSSAMP</ejb-name> 

                    <ejb-class>com.jee.ejbs.SessBean</ejb-class>

                 </session>               

              </enterprise-beans> 

</jboss:ejb-jar> 

it is showing following validation errors

The errors below were detected when validating the file "jboss-ejb3-2_0.xsd" via the file "jboss-ejb3.xml".  In most cases these errors can be detected by validating "jboss-ejb3-2_0.xsd" directly.  However it is possible that errors will only occur when jboss-ejb3-2_0.xsd is validated in the context of jboss-ejb3.xml.

src-resolve:can not resolve the name javaee:jboss-ejb-beanType to a(n) 'type definition' component -line 34

src-resolve:can not resolve the name javaee:jboss-ejb-jarType to a(n) 'type definition' component -line 36

src-resolve:can not resolve the name javaee:jboss-enterprise-beansType to a(n) 'type definition' component -line 38

this is a plain simple configuration,even without this file ,it is running,but for MDBs,ejb inter-communications,how this file is to be written
