Hi Sebastien,
now - I tried the beans in the testbeans and testbeans2 examples as well.
Hereafter I will present the some source code and output trace - both on the
client and the server.
1)Client source code:
import java.util.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import org.jboss.zol.testbean2.interfaces.AllTypesHome;
import org.jboss.zol.testbean2.interfaces.AllTypes;
public class TestClient {
public static void main(String[] args) {
try {
InitialContext ic = new InitialContext();
Object objref = ic.lookup("AllTypes");
System.out.println("lookup ok");
AllTypesHome home =
(AllTypesHome)PortableRemoteObject.narrow(objref,
AllTypesHome.class);
System.out.println("narrow ok");
AllTypes oAll = home.create("1");//this line is generating the
exception!!!
System.out.println("create ok");
} catch(Exception e) {
e.printStackTrace();
}
}
}
2) Server trace:

Here is the text of the e-mail that I sent you yesterday (just in case
you've missed it):
I downloaded the source code from
http://www.jboss.org/zip_archives/zola-cvs-sources.zip and compiled
and deployed
successfully the account manager demo example.
I got exactly the same problem - when the 'account manager' bean
tries to
get the home interface of the Account bean as in the code below:
private AccountHome getAccountHome() throws NamingException {
System.out.println("Trying to get account home...");
Context root = new InitialContext();
System.out.println("Got initial context!");
Object obj = root.lookup(ACCOUNT_REF);
System.out.println("Got an object reference...");
Object ref = PortableRemoteObject.narrow(obj,
AccountHome.class);
System.out.println("Object reference narrowed successfully!");
/*
* [TODO] handle ClassCastException of narrow
*/
return (AccountHome)ref;
}
It's throwing an exception on the line:
Object obj = root.lookup(ACCOUNT_REF);
on the server I get the message the the bean reference is null or
something
similar.
I tried to change this line of code as follows:
Object obj = root.lookup("java:comp/env/" + ACCOUNT_REF);
but it did not work as well.
Fortunatelly I managed to find the previous version of 'jboss' and
the same
code seems to work there just fine. However with it I get
'NullPointerException' when I try to create BMP beans.
In other words the last version of jboss seems to have fixed this
problem
but there is a bug in referencing one BMP bean from another.
Once again - I downloaded the last version of jboss about 3 or 4 days
ago.
Please help me.
Regards,
Kamen.
