My first EJB program seems to have a trouble. Sad

Following the "Tutorial: Developing Session Bean with EJB designer" in
the help file, I created a EBJ module that contains a simple session
bean called Item, which, in turn, has only one remote method:
AddItem(...)
When I tried to test it in the clientTest.java, it always fails on
calling this method. Following is the client test code in
clientTest.java
....
try {
cart = home.create(cardHolderName, creditCardNumber,
expirationDate);
} catch (Exception e) {
System.out.println("Could not create Cart session beann" + e);
}
if(cart!=null)
{
Item kassemBook = new Item("J2EE Blueprints", 39.99f, "Book");
// kassemBook has successfully been created
try {
cart.addItem(kassemBook); //failed on this line
} catch (Exception e) {
System.out.println("Could not add book (J2EE blutprints) to
the cartn" + e);
}
Following are the error messages:
org.omg.CORBA.BAD_OPERATION: minor code: 0 completed: No

The server is set to Borland Application Server 5.02 in JBuilder 7.
The server VM paramters is set to "-Dvbroker.agent.port=14000
-Dvbroker.security.disable=false" and the client VM paramter is set to
"-Dvbroker.agent.port=14000"

One thing worth to mention is that the statistic shows the session
bean is properly created in memory.
Any hint will be appreciated.
