Now I use Jersey to create restful web service on Websphere 8.5.
I also want the restful web service has the EJB 3.1's capacity.
My restful web service code as follow:
@Stateless
@Path("/tagServiceRS/{tagid}")
@Interceptors(TestTagServiceInterceptor.class)
public class TagServiceRS implements Serializable{
private static final long serialVersionUID = 5L;
private static final Logger log = LoggerFactory.getLogger(TagServiceRS.class);
@EJB
private TagTestService tagTestService;
@PersistenceContext(unitName = "tag-ejb")
private EntityManager entityManager;
@GET
@Produces("text/plain")
public String findTagById(@PathParam("tagid") String tagid) {
return "TAG";
}
/**
* @return the tagTestService
*/
public TagTestService getTagTestService() {
return tagTestService;
}
/**
* @param tagTestService the tagTestService to set
*/
public void setTagTestService(TagTestService tagTestService) {
this.tagTestService = tagTestService;
}
When I deploy the war on the Websphere 8.5. The TagServiceRS was successful deployed as a restful web service.And I test it. It's OK.
But the TagServiceRS was failed deploy as a EJB session bean.
The TagServiceRS's entityManager and tagTestService fields are all null.
I see the log, there is no error or warning log.
Below is my TagTestServiceBean code.
@Stateless
public class TagTestServiceBean implements TagTestService, Serializable {
private static final long serialVersionUID = 5L;
private static final Logger log = LoggerFactory.getLogger(TagTestServiceBean.class);
@Override
public Tag testFindTagById(Long id) {
log.info("testFindTagById ++++++++++++++++++++++++++++++++++++++++ invoked for id: {}", id);
return new Tag();
}
}
@Remote
public interface TagTestService extends Serializable {
/**
* @param id
* the ID from database
* @return a tag, may null
*/
Tag testFindTagById(Long id);
}
If Any Answers.Thanks a lot.
