Hi, I wanted the ejb references have been injected by container. When I use context.lookup, it is working. This is my code: | Context context = new InitialContext(); | PrStaffLocalInterface prstaff = (PrStaffLocalInterface)context.lookup("surgeonfish/PrStaffHome/local"); | prstaff.findById(new Integer(username)); | But if I use @EJB annotation I am taking null pointer exception. | package com.atosorigin.jdbc; | | import javax.ejb.EJB; | import javax.naming.Context; | import javax.naming.InitialContext; | import javax.persistence.EntityManager; | import javax.persistence.PersistenceContext; | | import com.atosorigin.utils.pojo.PrStaff; | import com.atosorigin.utils.pojo.PrStaffHome; | import com.atosorigin.utils.pojo.PrStaffLocalInterface; | | public class DBSecurity { | @EJB | PrStaffLocalInterface prStaff; | | public boolean checkUserPassword(String username, String password) throws Exception { | /*Context context = new InitialContext(); | PrStaffLocalInterface prstaff = (PrStaffLocalInterface)context.lookup("surgeonfish/PrStaffHome/local"); | prstaff.findById(new Integer(username));*/ | | prStaff.findById(new Integer(username)); | | return false; | } | } | | | //I HAVE USED ALL OF THIS POSSIBILITIES BY ONE BY | | | @EJB(mappedName="surgeonfish/PrStaffHome/local") | PrStaffLocalInterface prStaff; | | @EJB(beanName="surgeonfish/PrStaffHome/local") | PrStaffLocalInterface prStaff; | | @EJB(name="surgeonfish/PrStaffHome/local") | PrStaffLocalInterface prStaff; | | @EJB(name="PrStaffHome") | PrStaffLocalInterface prStaff; | | @EJB(name="PrStaffHome/local") | PrStaffLocalInterface prStaff; | | @EJB(mappedName="PrStaffHome/local") | PrStaffLocalInterface prStaff; | | @EJB(beanName="PrStaffHome/local") | PrStaffLocalInterface prStaff; | | @EJB(beanName="PrStaffHome") | PrStaffLocalInterface prStaff; | Where am I missing?
