EAServer 4.2.1 adds support for the proprietary EJB pass-by-reference mechanism supported by some other J2EE vendors. For more information, see “Optimizing in-server EJB calls” in Chapter 3, “Component Tuning,” in the EAServer Performance and Tuning Guide. This feature is not intended for new development, which should use standard EJB 2.0 local interfaces.
