![]() Building, Packaging, Deploying, and Running the address-book Application in NetBeans IDE You can do this using either NetBeans IDE orĪnt. This section describes how to build, package, deploy, and run the address-book application. Building, Packaging, Deploying, and Running the address-book Application The form doesn’t require any JavaServer Faces Each tag has an associated tag that will display validation error messages. Instance selected in the ContactController stateless The tags firstName and lastName are bound to the attributes in the Contact entity The following code snippet from the Create.xhtml Faceletsįile shows some of the input form for creating new Contact instances: Bean ValidationĬonstraints in JavaServer Faces backing beans, in this case in the Contact entity, automatically trigger validation when the forms are submitted. While JavaServerįaces has a form input validation mechanism using tags in Facelets XHTML files, address-book doesn’t use these validation tags. The address-book application uses a JavaServer Faces web front end to allow users to enter contacts. The resource bundle used in Spanish speaking locales. For example, ValidationMessages_es.properties is The form ValidationMessages_ locale-prefix.properties. Messages must be placed in a resource bundle properties file named ValidationMessages.properties in the default package, with localized resource bundles taking Properties file and the messages to be easily localized. This allows the validation messages to be located in one single In the resource bundle tut-install/examples/persistence/address-book/src/java/ValidationMessages.properties. The constraints in Contact, however, are strings Here are the relevant parts of the Contact entityĬlass: class Contact implements Serializable )$", The constraint is applied to the birthdayįield, which must be a in the past. Level domain, allowing only valid characters for emailĪn illegal comma character in the local name, will fail validation.Īre annotated with a constraint that definesĪ regular expression to match phone numbers of the form ( xxx) xxx– xxxx. On the email field matches email addresses of the form domain name. The regular expression declared in the annotation This constraint has two different uses in address-book. That the value of the attribute must match before the entity can be persisted ![]() The constraint defines a regular expression Bean Validation will throw a validationĮrror if the attribute is null when the entity is persisted or modified. ![]() The attribute must be set to a non-null value before theĮntity can be persisted or modified. The Contact entity uses the and constraints on theĪ required field. Bean Validation Constraints in address-book Validation) to validate the data stored in the persistent attributes of theĮntity, as described in Validating Persistent Fields and Properties. ![]() It uses a single entity class, Contact, that uses the Java API for JavaBeans Validation (Bean Web application that stores contact data. The address-book example application is a simple ![]()
