Not a good idea. The  element is to be used for J2EE application clients and should not be used as a method for deploying third party/utility jars. 

The correct way to do this is to define a Classpath entry in the MANIFEST.MF file of each J2EE module (ie EJB jar file/WAR file). 

Example MANIFEST.MF


  | 
  | Class-Path: jar1.jar jar2.jar
  | 
  | 

Note the path itself is relative to the root of the archive. So, for instance assuming you had an EAR structure such as


  | EAR
  |    -->lib
  |           jar1.jar
  |           jar2.jar
  | 
  | 

Your MANIFEST.MF should look as follows:


  | 
  | Class-Path: lib/jar1.jar lib/jar2.jar
  | 
  | 

Again, an entry like the one above should be placed in the MANIFEST.MF file of *each* J2EE module deployed inside your EAR file.
