  I am getting exception in the following line of code. 

userData = (em.createQuery("select u from Users u where u.email= ?1").setParameter(1, "mail at mailid.com")).getResultList();

userData   : is a List object, 
em  : is a EntityManager object
Users : is a table

Exception Message

Exception caught is : <4|true|0.9.7> org.apache.openjpa.persistence.ArgumentException: 
Could not locate metadata for the class using alias "Users".

    <persistence-unit name="userDatabase" transaction-type="RESOURCE_LOCAL"> 

           Please let me know if someone had already faced this issue and found a resolution for it.
