JSF Framework Services

• Model-View-Controller Architecture
  • View components "wired" to Model through beans
  • JSF acts as Controller, processing action and value change events

• Data Conversion - changing textual web form data into numbers, dates, and other data types

• Validation and Error Handling
  • Missing or incorrect input
  • Display of appropriate error messages

• Internationalization - character encodings and resource bundles

• Custom Components - when JSF components are not enough

• Alternative Renderers - e.g., for WML or XUL pages

• Tool Support - JSF is optimized for automated tools
