问题 is there a way to lookup an EJB in weblogic if it implements only local interface? If I use this @Remote public interface TestSessionRemote { public void businessMethod(); } @Stateless(mappedName = "A") public class TestSessionBean implements TestSessionRemote { public void businessMethod() { } } the EJB can be looked up using this name: "A#" + TestSessionRemote.class.getName() If I change the annotation for TestSessionRemote from @Remote to @Local the EJB disappears from JNDI. Is there a way

问题 I'm using struts2 junit 2.3.12 plugin.

问题 I have started working on AWS recently. I am currently working on developing upload functionality to S3 storage. As per my understanding there could be 2 ways to upload a file to S3:- Client's file gets uploaded to my server and i upload this file to S3 server using my credentials. [i will also able to hide this from client as i will not be showing the upload details.] Upload directly to S3 I was able to implement the first approach using simple upload api , but i want to skip the " write

问题 I'm building a REST API with jax-rs and WildFly 10 . Some of the endpoints are secured. I'm using FORM based authentication. In my javascript code, I check the response of the AJAX request, and if it is set to 401 Unauthorized , I then present a login form to the user. When he fills it in, I POST the details to j_security_check . Running on localhost this all works fine, but when the webserver and the REST server are on different machines, the browser denies the AJAX request due to cross

问题 I am trying to get the bytes of a particular file from the zipped file input stream. I have the input stream data of the Zipped file. From this I am getting the ZipEntry and writing the contents of each ZipEntry to a output stream and returning the byte buffer. This will return the buffer size output stream, but not the contents of each particular file. Is there a way I can convert the FileOutputStream to bytes or directly read the bytes of each ZipEntry? I need to return the ZipEntry

问题 I'm currently creating a backend server using Jersey 2.5.1 in a Tomcat 7. For the security I'm using the @RolesAllowed , @PermitAll etc. annotations, and I have created my custom ContainerRequestFilter and SecurityContext . My problem is that when my @RolesAllowed annotated resource is requested it always denies permission, even if I force my isUserInRole(role) method to return true . However, my filter method gets called. Do you have any suggestions? I'll paste some relevant code below. My

问题 I want to inject the current user using @Inject @Current User across all layers (i.e. web layer, EJB layer). In order to do this, I have the following CDI Producer method: @Named @SessionScoped public class UserController { @Resource SessionContext sessionContext; @EJB UserDao userDao; @Produces @Current public User getCurrentUser() { String username = sessionContext.getCallerPrincipal().getName(); User user = userDao.findByUsername(username); } } @Qualifier @Target({TYPE, METHOD, PARAMETER,
