Services with missing/unavailable dependencies error in JBoss EAP 6.2.0.GA - datasource

Question

I am trying to migrate my project war from Tomcat 6 to JBoss EAP 6.2.0. When trying to deploy the war I am getting the following exception:
16:58:58,493 WARN [org.jboss.as.ee] (MSC service thread 1-4) JBAS011001: Could not resolve resource-env-ref java:/mwdb
16:58:58,568 INFO [org.jboss.as.connector.deployers.jdbc] (MSC service thread 1-8) JBAS010403: Deploying JDBC-compliant driver class com.microsoft.sqlserver.jdbc.SQLServerDriver (version 4.0)
16:58:58,787 ERROR [org.jboss.as.server] (HttpManagementService-threads - 1) JBAS015870: Deploy of deployment "csc.war" was rolled back with the following failure message: {"JBAS014771: Services with missing/unavailable dependencies" => ["jboss.naming.context.java.module.csc.csc.env.jdbc.mwdb is missing [jboss.naming.context.java.jboss.resources.jdbc.mwdb]"]}
I am using MSSQL server as database and following is the configuration in my standalone.xml file.
<datasources>
<datasource jta="true" jndi-name="java:/mwdb" pool-name="jdbc/mwdb" enabled="true" use-java-context="true" use-ccm="true">

</datasource>
<drivers>
<driver name="sqlserver" module="com.microsoft.sqlserver.jdbc">
<datasource-class>com.microsoft.sqlserver.jdbc.SQLServerDataSource</datasource-class>
</driver>
</drivers>
</datasources>
I have placed sqljdbc4.jar and module.xml at jboss-as\modules\com\microsoft\sqlserver\jdbc\main.
My module.xml reads as follows:
<module xmlns="urn:jboss:module:1.1" name="com.microsoft.sqlserver.jdbc">
<resources>
<resource-root path="sqljdbc4.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
I have searched a lot about this issue in last two days and tried many things but nothing seems to work.
