In JavaEE 5 or earlier, EJBs must be packaged inside a ejb-jar file, which can be deployed standalone, or as part of an EAR. There are proposals for the next version to be able to package ejb classes inside WAR.

ejb-jar can reference library jars in its parent EAR library directory (by default EAR/lib/), or any other jars specified in ejb-jar's manifest.mf, or any other shared libraries installed in appserver. These library jars are good place for classes that may be shared by various ejb and non-ejb components.
