Did you include in your manifest file for every jar the Class-Path element poiting to which other archives it needs ?
The are only solutions !
Pope, how can i do this? Are you talking about ejb-ref tag in the Deployment Descriptor?

(more on this in SUN documentation -> Tools).
The MANIFEST.MF file may contain in the Main-Attributes section (see the docs...) the Class-Path: jar1 jar2...
