arguments in Remote Home interface methods

[Mikalai Zaikin]

Is it possible to define primitive arguments in
remote home interface methods ?
For example : EJB 2.0 specification, page 112

  
public interface AccountHome extends javax.ejb.EJBHome {
  public Account create(String firstName, String lastName,
   double initialBalance)
   throws RemoteException, CreateException;
  public Account create(String accountNumber,
   double initialBalance)
   throws RemoteException, CreateException,  LowInitialBalanceException;
  public Account createLargeAccount(String firstname,
   String lastname, double initialBalance)
   throws RemoteException, CreateException;
  ...
}

I'm quite unsure that there is error in specification. But I have read that
all arguments and returning types have to be serializable to be transferred over network (RMI calls). And primitives obviously can not implement serialazable
Maybe I have some mess in my head, sorry for confusing.
Thanks a lot.

yes primitives are allowed in remote home interfaces and they can be transported across the network.

System.out.println(int.class instanceof java.io.Serializable);
prints true

I think it is the same to the valid instance varibles of STATEFUL session beans. They can be primitive types although the specification does not explicitly define it in "7.4.1 Instance passivation and conversational state"

System.out.println(int.class instanceof java.io.Serializable);
prints true ?
Does this stmt print true for all java classes and primitive types suffixed with .class?

First of I want to say that my 2nd post has got nothing to do proving that primitives are serializable.
System.out.println(int.class instanceof java.io.Serializable);
return true because Class implements Serializable.
http://java.sun.com/j2se/1.4.1/docs/api/java/lang/Class.html
So the statement is true for all objcets class and also primitives.
Regarding the original question - All primitives are serializable.
