If you want to just extend one part of ObjectFactory, ie. to change how Result Types are build, you can implement dedicated ResultFactory
interface below and register it with dedicated name, see Extension Points for more details. Original ObjectFactory will use these dedicated factories to do the work. It's already done this way - the original functionality of ObjectFactory was extracted to separated classes which implements the interfaces below. Check the source of ObjectFactory to see more details. All these builders factories are available as from version 2.3.16 when StrutsObjectFactory
or its descendants is defined as struts.objectFactory - basically this should work with default Struts 2 installation and with the Spring plugin as well.
