Sun GlassFish Enterprise Server 2.1 Developer's Guide

The pass-by-reference Element

The pass-by-reference element in the sun-ejb-jar.xml file allows you to specify the parameter passing semantics for colocated remote EJB invocations. This is an opportunity to improve performance. However, use of this feature results in non-portable applications. See pass-by-reference in Sun GlassFish Enterprise Server 2.1 Application Deployment Guide.
