JetvsAdf
Oracle Jet is Oracle's JavaScript framework for building responsive web and hybrid mobile apps, while Oracle ADF is Oracle's Java-based framework. This document compares the two frameworks and discusses different approaches to using them together. It outlines key differences like Jet being open source with no official support while ADF is commercial. It also discusses pros and cons of combining Jet with ADF business components, faces, or controller. Alternatives to Jet like React, Vue, and Angular are also briefly presented.
