Problem with JNDI lookup in Glassfish V3

[Kamila Jolan]

Hi,

I got the application that works correctly on Glassfish V2, however when I try to migrate it to Glassfish V3 i have following exception:

javax.naming.CommunicationException: Can't find SerialContextProvider [Root exception is java.lang.ClassCastException]
at com.sun.enterprise.naming.SerialContext.getProvider(SerialContext.java:164)
at com.sun.enterprise.naming.SerialContext.lookup(SerialContext.java:409)

Caused by: java.lang.ClassCastException: Object is not of remote type com.sun.enterprise.naming.SerialContextProvider
at com.sun.corba.ee.impl.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:250)

Here is the method that do the lookup:

private final static String SESSION_IMPORT = "com.jmwrti.session.timetableimport.TimetableImportRemote";

/** Looks up a timetable import session bean on the server.
     * @return the timetable import bean */
    private TimetableImportRemote getTimetableImportDAO(Context jndiContext) {
        try {
            Object ref = jndiContext.lookup(SESSION_IMPORT);
            return (TimetableImportRemote)PortableRemoteObject.
                    narrow(ref,TimetableImportRemote.class);
        } catch (NamingException ex) {
            ex.printStackTrace();
        }
        return null;
    }

Here is the the interface:

 
@Remote
public interface TimetableImportRemote extends TimetableImportBase {
//some methods here }

The bean:

@Stateless
public class TimetableImportBean implements TimetableImportLocal, TimetableImportRemote {
..//some code here.}

I really dont understand why this is not working on Glassfish V3. I tried to remove the narrow method but the exception is still appearing. I am newbe to Glassfish and EJB so any help would be appreciated.

Thanks,
Kamila

What if you try with "TimetableImportBean" only? Or "TimetableImportRemote" without the full path?

[Kamila Jolan]

Hebert, thanks for answer, I still tried that but I still have that error.

[Hebert Coelho]

Could you do another test?

@Stateless(name="MyBean")
public class TimetableImportBean implements TimetableImportLocal, TimetableImportRemote
//.....

private final static String SESSION_IMPORT = "MyBean/remote";

Hi Hebert

I managed to get this working. I had forgot to create the JNDI entries for the JMS resource in Glassfish. Thanks for your help.
