JBAS014771: Services with missing/unavailable dependencies" => ["jboss.persistenceunit jboss.naming.context.java.DefaultDSMissing

[justin2013]

Hi,

Iam getting the below error when I start JBoss AS 7 standalone server in Windows 7.

16:07:16,875 ERROR
[org.jboss.as.server.deployment.scanner] (DeploymentScanner-t

hreads - 1)
{"JBAS014653: Composite operation failed and was rolled back. Steps

that failed:" =>
{"Operation step-2" => {"JBAS014771: Services with
missing/unavailable dependencies" =>
["jboss.persistenceunit.\"sample-afpj.war#forge-default

\"jboss.naming.context.java.DefaultDSMissing[jboss.persistenceunit.\"sample-afpj.war#forge-default\"jboss.naming.context.java.DefaultDS]"]}}}

My persistence.xml is given below:

xml version="1.0" encoding="UTF-8" standalone="no"?>

Datasource configuration in standalone.xml is shown below:

          <datasources>

                <datasource jndi-name="java:jboss/datasources/DefaultDS" pool-name="DefaultDS" enabled="true" use-java-context="true" use-ccm="true">

                    <connection-url>jdbc:mysql://localhost:3306/refapp</connection-url>

                    <driver>mysql</driver>

                    <security>

                    </driver>

                    <driver name="mysql" module="com.mysql"/>

                </drivers>

            </datasources>

module.xml is here:

<?xml version="1.0" encoding="UTF-8"?>

<module xmlns="urn:jboss:module:1.0" name="com.mysql">

  <resources>

    <resource-root path="mysql-connector-java-5.1.18-bin.jar"/>

  </resources>

  <dependencies>

    <module name="javax.api"/>

  </dependencies>

</module>

I have followed steps as given in link: 

https://zorq.net/b/2011/07/12/adding-a-mysql-datasource-to-jboss-as-7/

Could you kindly let me know how to resolve the same at earliest possible as iam doing poc  which uses jboss as 7 datasource..

THanks.
