make one ejb-jar uses another ejb-jar classess in the same EAR

I've an EAR which contains two ejb jars..

I need for the second EJB Jar to access classes from the first EJB Jar...

Should I changed the deployment assembly for the second EJB jar, or It by 开发者_运维技巧default can access the classes of all jars within the same EAR ?

Thanks.

By trying it againest OC4J 10.0.3.n, I found that all Jars in the same EAR can see classes in each others....
