running Richard Monson-Haefel book example

[Marcos Maia]

Maybe an easiest question is:
If i have a bean who imports another one, should I put it in the same jar file with the same deployment descriptor to find it�s classes??
Hi, I�m trying to run the Client_1 example of this book deployed in WL6.0 as u can see I�ve put some output to the console to check where the error occurs and I�ve show it at the code and having the error:
java.rmi.RemoteException: EJB Exception: ; nested exception is:
java.lang.NoClassDefFoundError: com.titan.cabin.CabinHome
java.lang.NoClassDefFoundError: com.titan.cabin.CabinHome
the deployment descriptor for the bean is:

<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC '-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN' 'http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd'>

    }
    String[] list = new String[vect.size()];
    vect.copyInto(list);
    return(list);
}

}
