javax.resource.ResourceException：IJ000453：无法获得托管连接

嗨，我在Jboss 7.1最终使用Spring 3应用程序，并且我创建了mysql社区服务器数据库，并且我在standalone.xml文件中添加了数据源，如下所示：javax.resource.ResourceException：IJ000453：无法获得托管连接

<datasources> 

       <datasource jta="true" jndi-name="java:/myapp" pool-name="myapp_pool" enabled="true" use-java-context="true" use-ccm="true"> 
        <connection-url>jdbc:mysql://localhost:3306/myapp</connection-url> 
        <driver>com.mysql.jdbc</driver> 
        <security> 
         <user-name>root</user-name> 
         <password>root</password> 
        </security> 
       </datasource> 
       <drivers> 

        <driver name="com.mysql.jdbc" module="com.mysql.jdbc"> 
         <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class> 
        </driver> 
       </drivers> 
      </datasources>

但我得到以下异常：
