Here is the exception error:

DEPLOYMENTS IN ERROR:

   Deployment "<UNKNOWN jboss.j2ee:ear=HousewareEnterpriseApplication.ear,jar=HousewareEnterpriseApplication-ejb.jar,name=RoleFacade,service=EJB3>" is in error due to the following reason(s): ** UNRESOLVED Demands 'persistence.unit:unitName=HousewareEnterpriseApplication.ear/HousewareEnterpriseApplication-ejb.jar#HousewareEnterpriseApplication-ejbPU' **

Here is the RoleFacade.java file:

package au.com.houseware.ejb.entity.bean;

import au.com.houseware.ejb.entity.Role;

import au.com.houseware.utils.RandomNumberUtil;

import javax.annotation.Resource;

import javax.ejb.Stateless;

import javax.persistence.EntityManager;

import javax.persistence.PersistenceContext;

@Stateless

public class RoleFacade extends AbstractFacade<Role> {

    @PersistenceContext(unitName = "HousewareEnterpriseApplication-ejbPU")

    private EntityManager em;

    @Resource

    private javax.transaction.UserTransaction utx;

    protected EntityManager getEntityManager() {

        return em;

    }

    public RoleFacade() {

        super(Role.class);

    }

    public void createRoleFromName(String name) {

        Role role = new Role();

        role.setRoleId((long)RandomNumberUtil.tinyId());

        role.setRoleName(name);

        super.create(role);

    }

}

What else I have missing from the project setup? or anything wrong in my RoleFacade file?

Very appreciate for any suggestion and guidance.

Thanks

Hi Sam,

does JBoss deploy your persistence.xml? Try for first step to skip your EJB from deployment to check, whether JBoss deploys JPA. (persistence.xml in META-INF of your .jar-File).

Best regards,

Hi Mark,

I have it resolved by added persistence.xml to the META-INF folder and re-normalized the database table relationship, and the remap all entities from database tables..

Thanks
