JNDI Setting of Hibernate on Websphere 6.x

Reference: Connection factory JNDI name practices
Using the direct JNDI DataSource, jdbc/xxxxxx, at Hibernate 3.X on Websphere 6.X has wrong message below:
J2CA0294W: Deprecated usage of direct JNDI lookup of resource jdbc/mysqlds.
The following default values are used: [Resource-ref settings]
or
J2CA0294W: 已棄用 jdbc/mysqlds 資源的直接 JNDI 查閱。使用下列預設值：[Resource-ref settings]
1.Just use Resource-ref in web.xml，add the resource setting, like

 <resource-ref id="ResourceRef_1268360344308">
  <res-ref-name>jdbc/MySQL</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Application</res-auth>
  <res-sharing-scope>Shareable</res-sharing-scope>
 </resource-ref>

  <resRefBindings xmi:id="ResourceRefBinding_1268360344308" jndiName="java:/comp/env/jdbc/mysqlds">
    web.xml#ResourceRef_1268360344308"/>
  </resRefBindings>

Then, the wrong message issue can be solved.
