Custom Component Implementation Summary

• A custom tag (corejsf:spinner) is used in a JSF page
• The tag is described in a TLD (tag library descriptor) file (spinner.tld), which also specifies the tag class
• The tag class (SpinnerTag.java) manages the tag attributes and also specifies the component type (com.corejsf.Spinner)
• The configuration file (faces-config.xml) associates the component type with the component class (UISpinner.java)
• The component class handles rendering of the user interface (encoding) and processing of user requests (decoding)

Here is a pictorial representation of the overall process.
