I have Spring bean as below:

@Service("bookService")
public class BookServiceImpl implements BookService {
@Autowired
@Qualifier("bookDao")
private BookDao bookDao;

i have a portlet trying access it as below:

62 public BookService getBookService() {
63 ApplicationContext springCtx = PortletApplicationContextUtils.getWebApplicationContext(getPortletContext());
64 return (BookService)springCtx.getBean("bookService");
}


but i have the below nullpointer exception:
java.lang.NullPointerException
at chapter09.code.listing.base.BookCatalogPortlet.getBookService(BookCatalogPortlet.java:64)
