How is Mojarra different from Sun's JSF Reference Implemenation?

Answer 1

The Sun JSF Reference Implementation, also known as Sun JSF RI, was named like that, just "JSF RI", from the beginning on (2004) until version 1.2_08 (2007). The dev team found "JSF RI" a boring and nothing-saying name and would like to give it a bit more identity and recognition. They wanted to have it in line with the "Glassfish" project which JSF RI is part of. After some user community polls (initiated by the good ol' forums.sun.com), the name "Mojarra" was been chosen. Since version 1.2_08, the name "JSF RI" has been replaced by "Mojarra". But it's essentially the same implementation. In other words, Mojarra is the JSF Reference Implementation.

Later, when Sun was taken over by Oracle in January 2010, the company name "Sun" was obviously replaced by "Oracle". And yet later, when Java EE was reowned by Eclipse instead of Oracle in September 2017, the "Java EE" project name was renamed to "Jakarta EE" (for legal reasons because Oracle owned "Java" trademark) and the company name "Oracle" throughout Jakarta EE was replaced by "Eclipse".

Later, with the release of Jakarta EE 10, the spec name "JSF" was renamed to "Faces" in an effort to de-acronymize as many as possible abbreviations within the Jakarta EE umbrella for clarity.

@JinKwon Click on the speaker icon at this page - Apparently it's \mōˈhärə\ -- "moArraa" – Ormsby

Apparently both Apache "TomEE+" and "TomEE Plume" have a JSF 2.2. implementation but "TomEE Plume" additionally has Mojarra: comparison. What does that mean? – Ormsby

@David: That the given TomEE version uses Mojarra instead of MyFaces as JSF implementation. – Audiogenic

Answer 2

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

Mojarra is the reference implementation of the Oracle JSF 1.x/2.x spec.
