| <h1>Proposal for <em>Validator</em> Package</h1> |
| </div> |
| |
| <h3>(0) Rationale</h3> |
| |
| <p>There is a need for the validation of JavaBeans to validate |
| user input from forms and validate business rules. There is also a |
| need to define different validation rules and error messages based on |
| the user's locale. |
| </p> |
| |
| <p>The Validator package will provide the capability to configure |
| validators (validation methods) with different method signatures. |
| So the basic framework can have an interface built on it to deal |
| with validations on web layers, ejb layers, etc. |
| </p> |
| |
| <h3>(1) Scope of the Package</h3> |
| |
| <p>The package shall create and maintain a package that provides |
| basic validation functionality. |
| </p> |
| |
| <p> |
| The package should : |
| <ul> |
| <li>Provide in an easy way to define validations for fields</li> |
| <li>Provide internationalization support for validation rules and error messages.</li> |
| <li>Provide an easy way to define validators</li> |
| <li>Provide a way to store information in a validator definition so JavaScript client |
| side validation can be auto-generated matching the server side validation.</li> |
| </ul> |
| </p> |
| |
| <p> |
| Non-goals: |
| <ul> |
| <li>This package does not auto-generate JavaScript client side code.</li> |
| </ul> |
| </p> |
| |
| <h3>(1.5) Interaction With Other Packages</h3> |
| |
| <p><em>Validator</em> relies on: |
| </p> |
| |
| <ul> |
| <li>Jakarta Regexp</li> |
| </ul> |
| |
| <h3>(2) Required Jakarta-Commons Resources</h3> |
| |
| <ul> |
| <li>Commons BeanUtils</li> |
| <li>Commons Collections</li> |
| <li>Commons Digester</li> |
| </ul> |
| |
| <ul> |
| <li>CVS Repository - New directory <code>validator</code> in the |
| <code>jakarta-commons</code> CVS repository.</li> |
| |
| <li>Initial Committers - The list is provided below. </li> |
| |
| <li>Mailing List - Discussions will take place on the general |
| <em>commons-dev@jakarta.apache.org</em> mailing list. To help list |
| subscribers identify messages of interest, it is suggested that the |
| message subject of messages about this component be prefixed with |
| [Validator].</li> |
| |
| <li>Bugzilla - New component "Validator" under the "Commons" product |
| category, with appropriate version identifiers as needed.</li> |
| |
| <li>Jyve FAQ - New category "commons-validator" (when available).</li> |
| </ul> |
| |
| |
| <h3>(4) Initial Committers</h3> |
| |
| <p>The initial committers on the Validator component shall be:</p> |
| |
| <ul> |
| <li><a href="mailto:dwinterfeldt@apache.org">David Winterfeldt</a></li> |
| </ul> |
