EJB @scheduler method invocation failed

Question

I am trying to work with @scheduler however it is failed to call my EJB2 object. Is it because @scheduler is in EJB 3.1 and I am trying to call EJB2 therefor it do not support it?? or is there something missing:

@Singleton
public class BatchUserPermissionUpdater {
                
Date now;   
@Inject
private IUserCompanyPermission permission;
@EJB
private CompanyBusiness companyBusiness;
                
@Schedule(minute="*/1",hour="*", persistent=false)
public void execute() {     
     now = new Date();
     Logger.instance().logInfo(this,"Executing scheduler. Time is :" + now);
                    
     List<UserCompanyPermission> userList= permission.findAllUserCompanyPermission();
        
     if(userList!=null && !userList.isEmpty()){
           updateAccess(userList);
                        }
                    }
        
public void updateAccess(List<UserCompanyPermission> userList)  {
    
     for ( UserCompanyPermission list : userList) {
       Company company =  companyBusiness.getCompanyBySID(list.getCompanyId());

               }
            }
        
        }

When It reach to line below it throw Exception:

Company company = companyBusiness.getCompanyBySID(list.getCompanyId());

@Stateless
public class CompanyFacadeImpl extends EntityServiceImpl<CompanyEntity, Long> implements CompanyBusiness {

@EJB
CompanyHome companyHome;

@Override
public Company getCompanyBySID(long id) throws RemoteException, FinderException {
    return companyHome.findByPrimaryKey(new SnapshotPK(id));
    }

}

CompanyHome :

public interface CompanyHome extends EJBHome {
 public Company findByPrimaryKey(SnapshotPK pk) throws RemoteException, FinderException;
}

Following exception is thrown:

    [org.jboss.as.ejb3.invocation] (EJB default - 1) JBAS014134: EJB Invocation failed on component Company for method public abstract com.iumnordic.snapshot.remote.Company com.iumnordic.snapshot.home.CompanyHome.findByPrimaryKey(com.iumnordic.snapshot.util.SnapshotPK) throws java.rmi.RemoteException,javax.ejb.FinderException: javax.ejb.EJBAccessException: JBAS014502: Invocation on method: public abstract com.iumnordic.snapshot.remote.Company com.iumnordic.snapshot.home.CompanyHome.findByPrimaryKey(com.iumnordic.snapshot.util.SnapshotPK) throws java.rmi.RemoteException,javax.ejb.FinderException of bean: Company is not allowed

Code above is working fine outside the scheduler throughout in application so I am sure it has something to do with @Scheduler what exactly it is not sure.
