https://community.jboss.org/message/762037#762037 -------------------------------------------------------------- Here is my Question: In the Jboss-ejb3.xml,its trying to reference http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd   something like this. <?xml version="1.0" 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"          ...                xmlns:c="urn:clustering:1.0"                              xsi:schemaLocation="http://www.jboss.com/xml/ns/javaee 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="2.0"> In the above,We are referencing both Schemas http://www.jboss.com/xml/ns/javaee jboss-ejb3-2_0.xsd (namespace is http://www.jboss.com/xml/ns/javaee ) and http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd (namespace is http://java.sun.com/xml/ns/javaee) under xsi:schemaLocation. jboss-ejb3-2_0.xsd  inturn references jboss-ejb3-spec-2_0.xsd something like this <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"            targetNamespace="http://www.jboss.com/xml/ns/javaee"            xmlns="http://www.jboss.com/xml/ns/javaee"            xmlns:javaee="http://java.sun.com/xml/ns/javaee"

namespace="http://java.sun.com/xml/ns/javaee" schemaLocation="jboss-ejb3-spec-2_0.xsd"/> There  is an ambiguity error or the Conflict that is Caused for  the Element <assembly-descriptorType> in both jboss-ejb3-spec-2_0.xsd and ejb-jar_3_1.xsd 1. jboss-ejb3-spec-2_0.xsd  Defines the Defines the Element <assembly-descriptorType> as below: <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"            targetNamespace="http://java.sun.com/xml/ns/javaee"            xmlns:javaee="http://java.sun.com/xml/ns/javaee"            xmlns:jboss="http://www.jboss.com/xml/ns/javaee"

</xs:sequence>             </xs:extension>          </xs:complexContent>       </xs:complexType>    </xs:redefine> It references assembly-descriptor like this: <xs:complexType

Element <assembly-descriptorType>   something like this <xsd:complexType name="assembly-descriptorType">     <xsd:annotation>       <xsd:documentation>         The assembly-descriptorType defines         application-assembly information.                 The application-assembly information consists of the         following parts: the definition of security roles, the         definition of method permissions, the definition of         transaction attributes for enterprise beans with         container-managed transaction demarcation, the definition         of interceptor bindings, a list of         methods to be excluded from being invoked, and a list of         exception types that should be treated as application exceptions.                 All the parts are optional in the sense that they are         omitted if the lists represented by them are empty.                 Providing an assembly-descriptor in the deployment         descriptor is optional for the ejb-jar or .war file producer.              </xsd:documentation>     </xsd:annotation>     <xsd:sequence>       <xsd:element name="security-role"                    type="javaee:security-roleType"

                   type="xsd:ID"/>   </xsd:complexType> Because of the above Scenario when I am trying to Validate the XML ,I am getting the following error: cos-nonambig: "http://java.sun.com/xml/ns/javaee":assembly-descriptor and "http://java.sun.com/xml/ns/javaee":assembly-descriptor (or elements from their substitution group) violate "Unique Particle Attribution". During validation against this schema, ambiguity would be created for those two particles. Attached are the 3 XSD Files. Could anyone help me resolve this.  -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/762037#762037] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
