what is 'call-by-reference' mean?

[Tsozum Tsozum]

EJBs by default resort to call-by-value - meaning data is copied during remote method call. This is inefficient. The call-by-reference is a bea specific feature that you can turn on/off by setting it true/false in weblogic-ejb-jar.xml. When you do, all the beans that are *colocated* will be called by reference which will yield better performance for you, since copying overhead is minimized.

It used to be true before WLS 8.1, but was set to false due to J2EE licensing restriction.

Thanks, ~vk
