To integrate ejb with JPA i follow this link http://theopentutorials.com/examples/java-ee/ejb3/how-to-create-ejb3-jpa-project-in-eclipse-jboss-as-7-1/

I have configured the datasource but still getting persistence.xml related exception. I am new to JBoss.can anyone tell me why i am getting this exception.

    //Persistence.xml
    <persistence xmlns="http://java.sun.com/xml/ns/persistence"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
    http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0">
    <persistence-unit name="persistence" transaction-type="JTA">
     <provider>org.hibernate.ejb.HibernatePersistence</provider>
     <jta-data-source>java:jboss/SMSCampaignDataSource</jta-data-source>
     <class>...</class>
 <properties>
  <property name="hibernate.dialect" 
      value="org.hibernate.dialect.PostgreSQLDialect"></property>
  <property name="show_sql" value="true"/>      
     </properties>
     </persistence-unit>

    </persistence>

Thanks.

You have to define the datasource in the standalone.xml and if you have already defined then please see whether your added datasource is saved or not.The stack trace clearly indicate that the problem is with datasource as persistence.xml is fine.I have face the same situation but in my case the changes that i have made in the standalone.xml was not getting saved as the JBoss directory was having the root privilege.So i edited and added the datasource in the standalone.xml with root privilege and the problem resolved of missing dependencies.

If your's is the different case then this link might help you : Services with missing/unavailable dependencies
