如何解组不同XML中具有多个名称空间的XML或忽略jaxb中的名称空间

Question

I have two XML's and corresponding Java files (created by trang.jar and xjc tools)

XML 1 :

If i unmarsh this
for XML 1

 HSIContractDetailModificationRQ hsi =  (HSIContractDetailModificationRQ) jaxbUnMarshallerForChannel.unmarshal(new StreamSource(new java.io.StringReader(xmlString)));

i get Exception :

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://axis.frontend.hsi.hotelbeds.com", local:"HSI_ContractDetailModificationRQ"). Expected elements are <{}HSI_ContractDetailModificationRQ>,<{}HSI_ContractDetailModificationRS>,<{}HSI_ContractInventoryModificationRQ>,<{}HSI_ContractInventoryModificationRS>

at com.sun.xml.internal.bind.v2.runtime.unmarshaller.Loader.reportError(Loader.java:238)  

If i unmarsh this
for XML 2

 HSIContractInventoryModificationRS  hsi = (HSIContractInventoryModificationRS)   jaxbContextForChannel.createUnmarshaller().unmarshal(new StreamSource(new java.io.StringReader(xmlInventoryRs)));

i get Exception :

javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.hotelbeds.com/schemas/2005/06/messages", local:"HSI_ContractInventoryModificationRS"). Expected elements are <{}HSI_ContractDetailModificationRQ>,<{}HSI_ContractDetailModificationRS>,<{}HSI_ContractInventoryModificationRQ>,<{}HSI_ContractInventoryModificationRS>
at com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallingContext.handleEvent(UnmarshallingContext.java:647)

I have seen in some site , it suggests to use package-info.java:

@XmlSchema(namespace = "http://axis.frontend.hsi.hotelbeds.com",    
elementFormDefault  =    
XmlNsForm.QUALIFIED)
  package com.cultagent4.hotelbeds.sa;
 import javax.xml.bind.annotation.*;    

I have used this , and xml 1 unmarshler works fine, but xml2 marshing fails .
Please help.

Answer 1

I am struggling with JAXB & XJC to build bindings to handle namespaces. I spent a lot of time on forums and googling. It does not works which makes me mad.

Atlast i have found a solution in a blog to ignore the namespace.
here is the solution link

Provided JAXB does not take into account namesapace of xml elements, it wrote the following code in order to ignore namespace while parsing.

JAXBContext jc = JAXBContext.newInstance("com.jmex.model.collada.collada_schema_1_4");
            Unmarshaller u = jc.createUnmarshaller();
            SAXParserFactory parserFactory;
            parserFactory = SAXParserFactory.newInstance();
            parserFactory.setNamespaceAware(false);
            XMLReader reader = parserFactory.newSAXParser().getXMLReader();
            Source er = new SAXSource(reader, new InputSource(sourceStream));
            HSIContractInventoryModificationRS hsi = (HSIContractInventoryModificationRS) u.unmarshal(er);

It works, JAXB unmarshalling is successful. (I hope this piece of code can help someone...)
