It is the same use case as obtaining action from IoC container. Advantages are clear - action/controller does not need to know: - what IoC we are using - how ( and where ) business logic objects are obtained A lot of things can be made really simple and easy to test if they do not know about MVC framework. And they can be reused.

This is usually considered antipattern in IoC world. I put a smal demo to show to my pimps - compiled deployable .war: http://www.pribluda.de/jobdemo.war And sources are donated to picocontainer: http://cvs.picocontainer.codehaus.org/viewrep/picocontainer/java/jobdemo It's webwork, but the same technique works with struts actions ( but not with tile controlers. yet :) ) regards, ----[ Konstantin Pribluda ( ko5tik ) ]---------------- Plugins for xdoclet-2 are released. check it out at: http://www.sourceforge.net/projects/xdoclet-plugins/ ----[ http://www.pribluda.de ]------------------------ __________________________________ Do you Yahoo!?
