While debugging the code the error point is....
Code:
List<CorporateElements> corporateElements = em.createNamedQuery("CorporateElements.findByCorporateId").setParameter("corporateId",new BigDecimal(Long.toString(2))).getResultList();
What I understand is that while an entity want to connect with the database its throwing the above Exception..
There is no problem for a JSP to communicate with database using session bean....It running fine..
Please help me out to sort the problem..
My persistence.xml looks like this...
Code:
