JAXB appending unneeded namespace declarations to tags

由 北战南征 提交于 2019-12-03 06:55:34
I'm implementing a homebrew subprotocol of XMPP, and i'm using combination of StAX and JAXB for parsing/marshalling mesages. And when I marshall a message I end up with loads of unneded namespace declarations: <ns2:auth xmlns:ns2="urn:ietf:params:xml:ns:ilf-auth" xmlns:ns4="ilf:iq:experiment:power" xmlns:ns3="ilf:iq:experiment:init" xmlns:ns5="ilf:iq:experiment:values" xmlns:ns6="ilf:iq:experiment:result" xmlns:ns7="ilf:iq:experiment:stop" xmlns:ns8="ilf:iq:experiment:end"> compton@ilf</ns2:auth> instead of: <ns:auth xmlns:ns="urn:ietf:params:xml:ns:ilf-auth>compton@ilf</ns:auth> Is there any

@XmlRegistry - how does it work?

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-03 04:36:41
问题 I have found some examples of JAXB2 @XmlRegistry over the internet but no good in-depth tutorials that talk about the concept of using @XmlRegistry with @XmlElementDecl , wonder if its a concept not much explored in general. Anyways here is my question, first some sample classes that I am using to unmarshall an xml using JAXB: The main class I am trying to unmarshal using JAXB - Employee.java package com.test.jaxb; import java.util.List; import javax.xml.bind.JAXBElement; import javax.xml

Why does JAXB sometimes map to JAXBElement?

由 偶尔善良 提交于 2019-12-02 22:43:27
There is a placeholder answer over at the unofficial guide with a link to an article which (to me) seems quite unrelated. I use XJC to generate my JAXB classes and while most of them map to each other as expected, some elements get mapped to JAXBElement<Foo> . This is most annoying for graphs with cycles, where sometimes the parent node of a Foo element will be the JAXBElement<Foo> , which doesn't itself have a parent property, breaking the cycle. I can think of various workarounds, but it would be much nicer if someone could explain this behaviour to me. Why does JAXB sometimes map a <Foo>

Flexible marshalling with JAXB

由 别等时光非礼了梦想. 提交于 2019-12-02 05:15:43
问题 I'm hoping to have a flexible way of marshalling objects. A verbose version for single objects and a less-verbose version for multiple object versions. For example, consider my department model: GET /locations/1: <location id='1'> <link rel="self" href="http://example.com/locations/1"/> <link rel="parent" href="http://example.com/serviceareas/1"/> <name>location 01</name> <departments> <department id='1'> <link rel="self" href="http://example.com/departments/1"/> <name>department 01</name> <

maven-jaxb2-plugin episode of same project in Maven, possible?

由 心已入冬 提交于 2019-12-02 04:01:59
问题 I have a basic.xsd and two other A.xsd and B.xsd . A.xsd and B.xsd get converted into two different java packages, therefore I need two Maven executions of the same plugin. Both XSDs refer to basic.xsd for some shared classes. If basic.xsd would come from a different project I could solve this problem really nicely through using episodes to prevent duplicate classes. But how can I refer to the current project? My first execution of the plugin is to generate only classes from basic.xsd into
