Hi,
I am trying to develop a CMP EJB 2.0 application and I found two problems,
both of them are the same listed below:
| java.rmi.ServerException: EJBException:; nested exception is:
| javax.ejb.EJBException: javax.naming.NameNotFoundException: ejb not
bound
|
The first one I have solved with the following code on the client,
| // Get an initial context
| InitialContext jndiContext = new InitialContext(properties);
| System.out.println("Got client context");
|
| // Get a reference to the Bean
| //Object ref = jndiContext.lookup("java:comp/env/ejb/Bookstore");
//java:comp/env/ejb/Bookstore
| //System.out.println("Got reference");
|
| // Get a reference from this to the Bean's Home interface
| BookstoreHomeRemote home = (BookstoreHomeRemote)
| PortableRemoteObject.narrow (jndiContext.lookup("BookstoreBean"),
BookstoreHomeRemote.class);
|
But when I use JNDI on the Session Bean to call the Entity Bean, then theserver
throws the exception above. The code is,
| public class BookstoreBean implements SessionBean{
|
| CMPBooksHomeRemote booksHome;
|
| public void ejbCreate() throws CreateException {
| }
|
| public Collection booksList(){
| Vector books = new Vector();
|
| try{
| Context ctx = new InitialContext();
| System.out.println("Got context in Session Bean");
|
| booksHome = (MPBooksHomeRemote)
ctx.lookup("java:comp/env/ejb/CMPBooksHomeRemote");
| System.out.println("Got booksHome");
|
| books = (Vector)booksHome.findAll();
|
| } catch(NamingException ne){
| throw new EJBException(ne);
| } catch(RemoteException re){
| throw new EJBException(re);
| } catch (FinderException fe) {
| throw new EJBException(fe);
| }
| return books;
| }
|
| public void ejbRemove(){}
| public void ejbActivate(){}
| public void ejbPassivate(){}
| public void setSessionContext(SessionContext sc){}
| }
|
This is the log,
| 2008-10-05 10:57:41,887 INFO [STDOUT] Got context in Session Bean
| 2008-10-05 10:57:41,888 ERROR [org.jboss.ejb.plugins.LogInterceptor]
