Java EE (Java Enterprise Edition) General Discussion

hi to all

i have a problem during marshal and unmarshal with JAXB 2.0.. i can marshall my xml to get an object instance and using it as unmmarshall input process..but the xml i get it's not valid because the root tag namespace prefix missing (this happen with both validation status(yes or no))..

what i do about unmarshall configuration is to add to package-info class the lines:

@javax.xml.bind.annotation.XmlSchema(
location="./myxml.xsd",
namespace = "http://it.netbureau/provaXml",
elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED,
xmlns = {
@javax.xml.bind.annotation.XmlNs
(
prefix = "tns",
namespaceURI="http://it.netbureau/provaXml"
)
}
)
package it.netbureau.main;


but the xml looks like :

<envelope xmlns:tns="http://it.netbureau/provaXml">
<tns:HEADLINE>...</tns:HEADLINE>
..
</envelope>

instead of <tns:envelope></tns:envelope> so as it gets the validation break down! because envelope haven't got a namespace prefix. this is strange because with qualified elementFormDefault nor unqualified the xml still wrong..

Why should this happen, how i can resolve this?

this is the stack trace error:

javax.xml.bind.UnmarshalException
- with linked exception:
[org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'ENVELOPE'.]

thank you
