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"                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"                xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee                 http://www.jboss.org/j2ee/schema/jboss-ejb3-2_0.xsd                 http://java.sun.com/xml/ns/javaee                 http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd"                version="3.1"                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 Posted by forums Original post: https://community.jboss.org/message/881526#881526
