As I say to you before, two bad things:
1) Your LectureEntity bean has a cmp field named questions, and a cmr field named also
questions. Remove the tags I indicate before:
| @ejb:persistent-field
| @jboss:column-name name="questions"
|
or rename one of them (cmp or cmr) and put the appropriate getter and setter.
2) The QuestionEntity (addQuestion parameter) is a remote interface. You cannot set a
cmr field with a remote interface (only a local). For that, you have two solutions:
2.1 : retrieve a local interface from your client if you can and change your method:
| public void addQuestion(QuestionEntityLocal question) {
| this.getQuestions().add(question);
| }
|
2.2 : if you can't, just pass the primary key and retrieve a local interface in the
method:
Add an ejb-ref to your bean:
| * @ejb.ejb-ref
| * ejb-name="QuestionEntity"
| * view-type="local"
|
Then in your method:
| public void addQuestion(Long questionId) {
| try {
| javax.naming.Context ic = new InitialContext();
| Object obj = ic.lookup(<Your Question bean JNDI name>);
| // Something like "java:comp/env/ejb/QuestionEntityLocal"
| QuestionEntityLocalHome Home =
(QuestionEntityLocalHome)PortableRemoteObject.narrow(obj,QuestionEntityLocalHome.class);
| QuestionEntityLocal question = Home.findByPrimaryKey(questionId);
| this.getQuestions().add(question);
| } catch(Exception e) {
| // Error handling
| }
| }
