How is Mojarra different from Sun\'s JSF Reference Implemenation?
Is it just a later version? Is it simply a rename?
Mojarra is the new name of the Sun's (sorry now Oracle) original JSF reference implementation (also known as JSF RI) from *version 1.2_08* onwards. Sun wanted a BUZZ word for its JSF implementation, so they gave a new name to their JSF implementation.
Mojarra is the default JSF shipped with servers like Glassfish ..etc
