8:30 a.m.
I`m having a problem while trying to run my application (Seam 1.2.1) on JBoss 4.0.5.
Let the code explain...

(QuestionCategoryManger)" action="#{QuestionCategoryManager.test}"/>
| </p>
| </h:form>
| </f:view>
| </body>
| </html>
|
QuestionCategoryManager
| import java.util.List;
| import javax.ejb.Local;
|
| @Local
| public interface QuestionCategoryManager {
| String test();
| void addCategory(String categoryName);
| void removeCategory(long id, boolean withQuestions);
| void removeCategory(String categoryName, boolean withQuestions);
| QuestionCategory getQuestionCategoryById(long id);
| QuestionCategory getQuestionCategoryByName(String categoryName);
| List<QuestionCategory> getAllQuestionsCategories();
| }
|
QuestionCategoryControllerBean
| mport javax.ejb.Stateless;
| import javax.persistence.EntityManager;
| import javax.persistence.PersistenceContext;
|
|
| /**
| *
| * @author W17chM4n
| */
|
| @Stateless(name="QuestionCategoryManger")
| public class QuestionCategoryManagerBean implements QuestionCategoryManager {
|
| @PersistenceContext
| private EntityManager em;
|
| public String test() {
| return "success";
| }
|
| public void addCategory(String categoryName) {
| em.persist(new QuestionCategory(categoryName));
| }
|
| public void removeCategory(long id, boolean withQuestions) {
| }
|
| public void removeCategory(String categoryName, boolean withQuestions) {
| }
|
| public QuestionCategory getQuestionCategoryByName(String categoryName) {
| return (QuestionCategory)em.createQuery("from QuestionCategory q where
q.categoryName='" + categoryName + "'").getSingleResult();
| }
|
| public QuestionCategory getQuestionCategoryById(long id) {
| return (QuestionCategory)em.createQuery("from QuestionCategory q where
q.id="+String.valueOf(id)).getSingleResult();
| }
|
| public List<QuestionCategory> getAllQuestionsCategories() {
| return em.createQuery("from QuestionCategory q").getResultList();
| }
| }
|
So here it is. I`m building it with maven, and while deploying, everything is allright.
But when i push the button i get this:

I don`t know why seam can`t find ejb bean. Is there a way to test if SeamInterceptor is
running ?
JNDI Namespace tells that the bean exists:
| +- Inquisitor (class: org.jnp.interfaces.NamingContext)
| | +- QuestionCategoryManger (class: org.jnp.interfaces.NamingContext)
| | | +- local (proxy: $Proxy191 implements interface
com.blstream.inquisitor.ejb3.interfaces.QuestionCategoryManager,interface
org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
|
Can anybody help me ?
