XML Doctype validation with JBoss 7.1.1.Final AS

Question

While developing a J2EE application on JBoss AS 7.1.1.Final , I've been defining some configuration files as follows:

xa-orchestrator-ds.xml (note that my datasource is a MySQL instance):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss-web PUBLIC
        "-//JBoss//DTD Web Application 5.0//EN"
        "http://www.jboss.org/j2ee/dtd/jboss-web_5_0.dtd">
<datasources>

    ...

</datasources>

jboss-web.xml :

<!DOCTYPE jboss-web PUBLIC "http://www.jboss.org/j2ee/dtd" "http://www.jboss.org/j2ee/dtd/jboss-service_5_0.dtd">
<jboss-web>

    ...

</jboss-web>

web.xml :

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">

    ...

 </web-app>

This configuration causes a runtime exception related to XML validation:

12:28:50,676 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC00001: Failed to start service jboss.deployment.unit."MIUR_PRISMA-2.1-BusinessLayer.war".PARSE: org.jboss.msc.service.StartException in service jboss.deployment.unit."MIUR_PRISMA-2.1-BusinessLayer.war".PARSE: Failed to process phase PARSE of deployment "MIUR_PRISMA-2.1-BusinessLayer.war"

Indeed, by removing the doctype definition from xa-orchestrator-ds.xml , it works fine.

Which is the properly configuration by including right doctypes?

Starting with J Boss Application Server 7.1.0.Final you have the ability to deploy a -ds.xml file following the schema:

http://docs.jboss.org/ironjacamar/schema/datasources_1_1.xsd

Eg:

<datasources xmlns="http://www.jboss.org/ironjacamar/schema">
  <datasource jndi-name="java:jboss/datasources/MySqlDB" pool-name="MySQLPool">
      <connection-url>jdbc:mysql://localhost:3306/as7db</connection-url>
      <driver>mysql-connector-java-5.1.18-bin.jar</driver>
      <pool>
          <max-pool-size>30</max-pool-size>
      </pool>
      <security>
          <user-name>user</user-name>
          <password>...</password>
      </security>
  </datasource>
</datasources>

EDIT:

Another way is add the schemaLocation

<datasources xmlns="http://www.jboss.org/ironjacamar/schema"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://www.jboss.org/ironjacamar/schema http://docs.jboss.org/ironjacamar/schema/datasources_1_1.xsd">

</datasources>
