Here's the relevant passage:

"Components in the EJB container may have access to the following 
classes and resources. Portable applications must not depend on having 
or not having access to these classes or resources.
[...]
* The content of any EJB jar files included in the same ear file.
* The content of any client jar files specified by the above EJB jar files."

Thus it is correct to require an explicit Class-Path between EJB JARs 
within an application.
