| [eclipselink-users] MOXy JAXB Eclipselink Workbench - wrong unmarshall |
Hello,
can you please help me to understand what's wrong in my simple unmarshall example?
Libraries used:
- jdk 1.5.0_16
- EclipseLink 2.2.0
- javax.xml.stream_1.0.1
- javax.xml.bind_2.2.0
Xml file:
<PaymentInf>
<id>pmtid</id>
<PmtInf>
<service>
<id>SEPA</id>
</service>
<amount>
<val>1</val>
</amount>
<date>2010-12-27</date>
</PmtInf>
<CreditorFrstName>
<cd>myfrstname</cd>
<id>frstId</id>
</CreditorFrstName>
<CreditorLstName>
<cd>mylastname</cd>
</CreditorLstName>
</PaymentInf>
java classes (getter and setter are here hidden):
public class PaymentInf {
private String id;
private String service;
private BigDecimal amount;
private Date date;
private Creditor creditor;
}
public class Creditor {
private String firstName;
private String lastName;
private String id;
}
Test code:
JAXBContext context = JAXBContextFactory.createContext("payment", getClass().getClassLoader());
InputStream payment = getClass().getClassLoader().getResourceAsStream("payment.xml");
Unmarshaller unmarshaller = context.createUnmarshaller();
PaymentInf pmt = (PaymentInf) unmarshaller.unmarshal(payment);
It works properly only if i map all xml fields and only if <id> tag is not duplicated (i have to change service id tag to idserv and creditorFrstName id tag to idcred).
If i didn't map the <service> tag and <id> field is duplicated then:
- amount is null
- date is null
- id is null
- service is null
- creditor firstName is properly unmarshalled
- creditor lastName is properly unmarshalled
- creditor id is "frstIdfrstId" (duplicated)
If i didn't map the <service> tag and <id> field is not duplicated then:
- amount is null
- date is null
- id is properly unmarshalled
- service is null
- creditor firstName is properly unmarshalled
- creditor lastName is properly unmarshalled
- creditor id is is properly unmarshalled
What is wrong?
Thank you for your attention,
Daniele
