constant declarations - public final static

[chandana sapparapu]

In chapter 4 of MZ's study guide, he mentions the following-

A Web service endpoint interface must conform to the rules of a JAX-RPC service definition interface:
�It MUST NOT have constant declarations, such as public final static.

What is the logic behind this?

In session beans, is there a requirement that we should not declare constants using public static final? I understand that static final should not be used for ejbCreate or for business methods, but I don't recall a rule against using constants in a bean.

Thanks

sorry, I realized it after posting the message, the rule is about the component interface, not the bean.

Anyway, still curious about why we shouldn't use constant declarations in the interface..

Thanks
