Consider using a session bean as a service for accepting and returning XML byte
streams, but delegating the actual parsing and file handling to specific (non-EJB)
handlers. The intent is to write non-EJB, reusable components and then wrap these
components in session beans to form a scalable service layer. These components
can then exist outside the context of an EJB environment. In most cases you'll want
XML handlers that aren't forever and always used in EJBs.
