Wildfly 9 datasource spring jpa missing dependencies error on openshift - spring-data

Question

I am want to deploy an application with spring jpa using datasource from wildfly9, I think I have all configuration needed but I am getting an error.
What i have is
standalon.xml in subsystem
<datasource jndi-name="java:jboss/datasources/PostgreSQLDS"
jta="true" enabled="${postgresql.enabled}"
use-java-context="true"
pool-name="PostgreSQLDS"
use-ccm="true">
<connection-url>
jdbc:postgresql://${env.OPENSHIFT_POSTGRESQL_DB_HOST}:${env.OPENSHIFT_POSTGRESQL_DB_PORT}/${env.OPENSHIFT_APP_NAME}
</connection-url>
<driver>postgresql</driver>
<security>
<user-name>${env.OPENSHIFT_POSTGRESQL_DB_USERNAME}
</user-name>
<password>
${env.OPENSHIFT_POSTGRESQL_DB_PASSWORD}
</password>
</security>
<validation>
<check-valid-connection-sql>SELECT 1</check-valid-connection-sql>
<background-validation>true</background-validation>
<background-validation-millis>60000</background-validation-millis>
</validation>
<pool>
<flush-strategy>IdleConnections</flush-strategy>
</pool>
</datasource>
<drivers>
<driver name="postgresql" module="org.postgresql.jdbc">
<xa-datasource-class>org.postgresql.xa.PGXADataSource</xa-datasource-class>
</driver>
</drivers>
my spring.profile.xml has
<beans:bean id="dbDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<beans:property name="jndiName" value="java:jboss/datasources/PostgreSQLDS"/>
</beans:bean>
and the error i am getting is
[0m[31m08:57:40,995 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "ROOT.war")]) - failure description: {"WFLYCTL0180: Services with missing/unavailable dependencies" => [

"jboss.persistenceunit.\"ROOT.war#my-jpa\" is missing [jboss.naming.context.java.\"\\n java:comp\".env.jdbc.\"PostgreSQLDS\\n \"]"
]}
I am not sure what i am doing bad, any help is welcome

Try this JNDI resource mapping with java:comp/env and you need datasource resource reference in your app using jboss-web.xml below.
<beans:bean id="dbDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<beans:property name="jndiName" value="java:comp/env/jdbc/PostgreSQLDS"/>
</beans:bean>
Add jboss-web.xml inside WEB-INF folder with this content
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.jboss.com/xml/ns/javaee
http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd">
<context-root>/myAppRoot</context-root>
<resource-ref>
<res-ref-name>jdbc/PostgreSQLDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<jndi-name>java:jboss/datasources/PostgreSQLDS</jndi-name>
</resource-ref>
</jboss-web>
