[esb-issues] [JBoss JIRA] Updated: (JBESB-815) JAXB-Intros @XmlAttribute annotation handling issue

JAXB-Intros @XmlAttribute annotation handling issue --------------------------------------------------- Key: JBESB-815 URL: http://jira.jboss.com/jira/browse/JBESB-815 Project: JBoss ESB Issue Type: Bug Security Level: Public(Everyone can see) Components: Transports, Web Services Affects Versions: 4.2 Milestone Release 3 Environment: Windows XP v2002 sp2, JAVA 1.5_02 Reporter: Sylvia Isler Assigned To: Tom Fennelly Fix For: 4.2.1 Attachments: patch.tar.bz2 JAXB with JAXB-introductions fails to Marshall @XmlAttribute annotations in the following example: The following class contains a simple double for an attribute: public class UnitPrice { public double value; UnitPrice(double value){ this.value=value; } UnitPrice() { } public double getValue() { return this.value; } } The following JAXB-intros config file was used <?xml version = "1.0" encoding = "UTF-8"?> <jaxb-intros xmlns="http://www.jboss.org/xsd/jaxb/intros"> <Class name="junit.prices.UnitPrice"> <XmlType name = "UnitPrice"/> <Field name="value"> <XmlAttribute name="value" required="true" /> </Field> </Class> </jaxb-intros> along with the following schema file: <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified"> <xs:element name="UnitPrice"> <xs:complexType> <xs:attribute name="value" type=xs:double use="required"/> <xs:attribute name="currency" use="optional"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="USD"/> <xs:enumeration value="Euro"/> <xs:enumeration value="JPY"/> </xs:restriction> </xs:simpleType> </xs:attribute> </xs:complexType> </xs:element> </xs:schema> To unmarshall this XML file: <?xml version="1.0" encoding="UTF-8"?> <UnitPrice value="40.0" xsi:noNamespaceSchemaLocation="C:\UnitPrice.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> I then used the following code to test the unmarshalling of the above XML. JaxbIntros config = IntroductionsConfigParser.parseConfig(getClass().getResourceAsStream("UnitConfig.xml")); ClassIntroConfig classIntroConfig = config.getClazz().get(0); assertEquals(UnitPrice.class.getName(), classIntroConfig.getName()); IntroductionsAnnotationReader reader = new IntroductionsAnnotationReader(config); Map<String, Object> jaxbConfig= new HashMap<String, Object>(); jaxbConfig.put(JAXBRIContext.ANNOTATION_READER, reader); JAXBContext jaxbContext = JAXBContext.newInstance(new Class[] {UnitPrice.class}, jaxbConfig); Unmarshaller unmarshaller = jaxbContext.createUnmarshaller(); JAXBElement jbe = null; UnitPrice order =null; StreamSource ss = new StreamSource(getClass().getResourceAsStream("UsdUnitPrice1.xml")); jbe = unmarshaller.unmarshal(ss, UnitPrice.class); order =(UnitPrice)jbe.getValue(); try{ assertEquals("get double value error", 40.0, order.getValue()); } catch (Exception e) { fail(e.getMessage()); } a UnitPrice instance is instantiated. However, the above test code fails because the value attribute of the unmarshalled UnitPrice instance is 0.0 instead of 40.0.. After some discussion on the forums, I decided to try using <Method> tag instead of the <Field> in the config file above. When this yielded the same result,
