Hi,
I am currently experimenting with EJB.
I receive java.lang.ClassCastException: $Proxy489 cannot be cast to com.jbossatwork.ejb.InventoryFacadeLocalHome
error when I cast the EJBLocalHome object to the Class InventoryFacadeLocalHome.

My JNDI look up is OK.
what could be my problem.

Context c = new InitialContext();
System.out.println( "lookupInventoryFacadeBean");
Object localObj = c.lookup("java:comp/env/ejb/InventoryFacadeLocal");
System.out.println( "1. class name [" +localObj.toString()+"]");

EJBLocalHome localHome = null;

localHome = (EJBLocalHome) localObj;
if (localHome != null) {
System.out.println("localHome is not null");
} else {
System.out.println("localHome is null");
}

System.out.println("2. class name [" + localHome.toString() + "]");
InventoryFacadeLocalHome rv = (InventoryFacadeLocalHome)localHome;
System.out.println("3. class name [" + localHome.toString() + "]");

my output is
