Jaxb setvalidating

La manipulation du document XML se fait en utilisant des objets précédemment générés à partir d'une DTD pour JAXB 1.0 et d'un schéma XML du document à traiter pour JAXB 2.0.

Le page officiel de JAXB est à l'url : chapitre contient plusieurs sections : JAXB est l'acronyme de Java Architecture for XML Binding.

JAXB est une spécification qui permet de faire correspondre un document XML à un ensemble de classes et vice versa au moyen d'opérations de sérialisation/désérialisation nommées marshalling/unmarshalling.

JAXB permet aux développeurs de manipuler un document XML sans avoir à connaître XML ou la façon dont un document XML est traité comme cela est le cas avec SAX, DOM ou St AX.

JAXB au contraire fournit un outil qui analyse un schéma XML et génère à partir de ce dernier un ensemble de classes qui vont encapsuler les traitements de manipulation du document.

Le grand avantage est de fournir au développeur un moyen de manipuler un document XML sans connaître XML ou les technologies d'analyse.

I described how to validate an object model (mapped with JAXB annotations) against an XML schema using the validation APIs. The event is represented as an instance of Validation Event, and provides many details about the issue. The 3rd event is related to the extra "phone-number" element. The 3rd event is related to the extra "phone-number" element.

In this post I'll describe how to leverage those APIs during unmarshal and marshal operations.package validation; import The data is quite similar to what is available from a SAXParse Exception. EVENT SEVERITY: 1 MESSAGE: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'. SAXParse Exception: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'. EVENT SEVERITY: 1 MESSAGE: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'. Validating Marshal Record$Marshal SAXParse Exception: cvc-max Length-valid: Value 'Jane Doe' with length = '8' is not facet-valid with respect to max Length '5' for type 'string With Max Size5'.

To run the examples, you'll need the most current Early Access 3 version of the JAXB 2.0 Reference Implementation. Schema Factory; public class Unmarshal Demo The validation performed during the unmarshal raised 3 events. Schema Factory; public class Marshal Demo The validation performed during the marshal raised 3 events.LOCATOR LINE NUMBER: 3 COLUMN NUMBER: 25 OFFSET: -1 OBJECT: null NODE: null URL: null EVENT SEVERITY: 1 MESSAGE: cvc-complex-type.2.4.d: Invalid content was found starting with element 'customer'. [email protected] NODE: null URL: null EVENT SEVERITY: 1 MESSAGE: cvc-type.3.1.3: The value 'Jane Doe' of element 'name' is not valid. Validating Marshal Record$Marshal SAXParse Exception: cvc-type.3.1.3: The value 'Jane Doe' of element 'name' is not valid. Xml Root Element; @Xml Root Element public class Customer . The first 2 events are related to the text value of the "name" element being too long. The first 2 events are related to the text value of the "name" element being too long.Returning false from the handle Event method will cause the JAXB operation to stop, returning true will allow it to continue (if possible).package validation; import LOCATOR LINE NUMBER: 3 COLUMN NUMBER: 25 OFFSET: -1 OBJECT: null NODE: null URL: null EVENT SEVERITY: 1 MESSAGE: cvc-type.3.1.3: The value 'Jane Doe' of element 'name' is not valid.

LOCATOR LINE NUMBER: 7 COLUMN NUMBER: 12 OFFSET: -1 OBJECT: null NODE: null URL: null package validation; import LOCATOR LINE NUMBER: -1 COLUMN NUMBER: -1 OFFSET: -1 OBJECT: validation.Hi Andrew, Validating is indeed deprecated and you need to set the Schema object to validate against. = To question ----------------\ Paul Sandoz x38109 33-4-76188109 --------------------------------------------------------------------- To unsubscribe, e-mail: [hidden email] For additional commands, e-mail: [hidden email] Thanks for your dedication to the list, Paul.In this respect i am unsure how you can create a general validating mechanism unless you keep a map of known JAXB class to Schema instance. We have resolved this issue without needing to maintain a map of JAXB classes.Abstract Container Entity(Abstract Container Request.java:179) [stack trace truncated] Am I on the right track here?As I understand it, the call to set Validating is deprecated in JAXB 2.0 and I should use set Schema. If so, how can I have my Validating JAXBContext class create an appropriate validation.JAXB 2.0, JSR 222, includes a number of important improvements to JAXB 1.0.Some of these are: This tip demonstrates two of these improvements: validation (as a part of marshalling and unmarshalling) using the JAXP validation APIs, and Java-to-Schema binding.
