Can JSF 2.0 be used with WebSphere Application Server version 7.x?
If so, how?
The WebSphere Infocenter indicates that the right way to change to an alternative JSF implementation is to create a WebSphere Shared Library with the isolated classloader option enabled.
Any modules that need JSF 2 would be associated with the new shared library, and then the application would start with JSF 2 instead of JSF 1.2.
It is also necessary to have fix pack 7.0.0.19 or later installed.
