Multiple DataSource into Websphere Liberty Profile - jdbc

Question

Is it possible to declare multiple DataSources into Websphere Liberty Profile server.xml ? any examples ?
I try to do it but I can see only one. When the second one is looked up I have an error message that says the jndi name is not found.
My server.xml :
<?xml version="1.0" encoding="UTF-8"?>
<server description="new server">
<!-- Enable features -->
<featureManager>
<feature>webProfile-7.0</feature>
<feature>jndi-1.0</feature>
<feature>jdbc-4.0</feature>
</featureManager>
<!-- To access this server from a remote client add a host attribute to the following element, e.g. host="*" -->
<httpEndpoint id="defaultHttpEndpoint"
httpPort="9080"
httpsPort="9443" />
<!-- Automatically expand WAR files and EAR files -->
<applicationManager autoExpand="true"/>
<!-- Configuration for DSPB -->
<jndiEntry jndiName="dspb/configuration/files" value="classpath:properties/dspb.properties,classpath:properties/dspb_db_connector.properties" />
<dataSource id="ds1" jndiName="DB_DSPB_ACTIVITI" connectionManagerRef="connectionManager1" jdbcDriverRef="MyJDBCDriver">
<properties.oracle driverType="thin" databaseName="xe"
serverName="localhost" portNumber="1521"
user="dspb_activiti" password="dspb_activiti"/>
</dataSource>
<dataSource id="ds2" jndiName="DB_DSPB" connectionManagerRef="connectionManager2" jdbcDriverRef="MyJDBCDriver">
<properties.oracle driverType="thin" databaseName="xe"
serverName="localhost" portNumber="1521"
user="dspb" password="dspb"/>
</dataSource>
<connectionManager id="connectionManager1" maxPoolSize="20" minPoolSize="5"
connectionTimeout="10s" agedTimeout="30m"/>
<connectionManager id="connectionManager2" maxPoolSize="20" minPoolSize="5"
connectionTimeout="10s" agedTimeout="30m"/>
<jdbcDriver id="MyJDBCDriver">
<library>
<fileset dir="C:/oraclexe/app/oracle/product/11.2.0/server/jdbc/lib/" includes="ojdbc6.jar"/>
</library>
</jdbcDriver>
</server>
And the definitions in web.xml :
<resource-ref>
<res-ref-name>DB_DSPB</res-ref-name>
<res-type>javax.sql.ConnectionPoolDataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
<resource-ref>
<res-ref-name>DB_DSPB_ACTIVITI</res-ref-name>
<res-type>javax.sql.ConnectionPoolDataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
<resource-ref>
<res-ref-name>dspb/configuration/files</res-ref-name>
<res-auth>Container</res-auth>
</resource-ref>
And I can only see DSPB in jconsole view : http://i.stack.imgur.com/euN8e.jpg
What's wrong ?
So, the ibm-web-bnd.xml was missing, cheaty thing...
<web-bnd
xmlns="http://websphere.ibm.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-bnd_1_0.xsd"
version="1.0">
<resource-ref name="DB_DSPB" binding-name="DB_DSPB"/>
<resource-ref name="DB_DSPB_ACTIVITI" binding-name="DB_DSPB_ACTIVITI"/>

Yes this is possible. Simply specify separate <dataSource> elements in your server.xml.
For example:
<dataSource id="ds1" jndiName="jdbc/ds1" jdbcDriverRef="MyJDBCDriver">
<properties ... />
</dataSource>
<dataSource id="ds2" jndiName="jdbc/ds2" jdbcDriverRef="MyJDBCDriver">
<properties ... />
</dataSource>
Note that both datasources have a jdbcDriverRef on them, which corresponds to the ID of a <jdbcDriver> element. This is convenient so you don't have to specify another JDBCDriver each time you want to declare a <dataSource>.
<jdbcDriver id="MyJDBCDriver">
<library>
<fileset dir="${server.config.dir}/jdbcDrivers" includes="driver.jar"/>
</library>
</jdbcDriver>
Alternatively, you can nest <jdbcDriver> elements under a datasource if you choose to. This would be ideal if you never share a <jdbcDriver> between multiple <dataSource> elements.
<dataSource id="ds1" jndiName="jdbc/ds1">
<properties ... />
<jdbcDriver>
<library>
<fileset dir="${server.config.dir}/jdbcDrivers" includes="someJDBCDriver.jar"/>
</library>
</jdbcDriver>
</dataSource>
