  • Cocoon has not always been this way, but has increased in the number of features over the years.
  • {1} represents the value of the ** in the match pattern
  • Model: The form model is defined by a form definition. This is an XML file describing the structure of the form. Template: The presentation of the form is (usually) handled by a form template. The form template is an XML file (e.g. an XHTML file, but this could be any markup). Binding: To fill the form with data from a bean or XML document, a binding framework is available.
  • Picture taken from: http://www.flickr.com/photos/mell242/46500577/ A continuation is a representation of some of the execution state of a program at a certain time.
  • A very cool demonstration of the power of Cocoon
