3. and also i have Local Stateless session bean
| @Local(BillAdminManagement.class)
| @Stateless
| @Name("billAdmin")
| public class BillAdminManagementBean implements BillAdminManagement{
|
| @PersistenceContext
| private EntityManager entManager;
|
| @Logger
| private Log log;
|
| public List<Language> getLanguages() throws Exception {
| try {
| List<Language> list = entManager.createNamedQuery("Language.getAllLanguages").getResultList();
| log.info("List Size = "+list.size());
| return null;
| } catch (Exception e) {
| log.error("Error While Getting Languages",e);
| throw e;
| }
| }
| }
|
how i can fill dropdownbox component from this method on page startup?
