Custom namespace prefix in JAXB

[gquintana]

Hello,

I need to customise the namespace prefix used in outgoing XML HTTP requests.

Outside ServiceMix, the following code does the job:

But once in ServiceMix, it raises an exception:



Obviously, the com.sun.xml.bind.namespacePrefixMapper property is not
supported. What's the appropriate way to do it? Which implementation of JAXB
is used in ServiceMix 5.4.1 / Java 7?

Thanks for your help,
Gerald

Try adding a package-info.java to the annotated class, and fill in with
something similar to the following

@XmlSchema(namespace = "http://example.org/main-namespace",
elementFormDefault = XmlNsForm.QUALIFIED, xmlns = {
@XmlNs(prefix = "my", namespaceURI = "
http://example.org/main-namespace")
@XmlNs(prefix = "other", namespaceURI = "
http://example.org/other-referred-namespace")
})
package my.package;

import javax.xml.bind.annotation.XmlNs;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;


consider that @XmlNs is only a "suggestion" and often it is ignored

Thanks for you advice, I tried this solution but:
- I can not make the cxf-xjc-plugin Maven plugin generate the appropriate
package-info.java
- The generated XML contains a "ew:" behind each element and I need to have
it only on the root element.

I recognize the endpoint I am compelled to access sucks.

I tried to marshal un JAXBElement with QName speciying the prefix, but it
doesn't help.

My only option left, is doing search/replace on the generated String
message. This solutions is abominable as well.

Yes, sorry, my advice is applicable to a Java First approach, where I add
the package-info.java manually
I don't use cxf-xjc-plugin but I write JaxB annotated Java and generate XML
Schemas and WSDL from it...

"- The generated XML contains a "ew:" behind each element and I need to have
it only on the root element."
maybe this depend on the elementFormDefault: if it is QUALIFIED, every
element will use the prefix, try with UNQUALIFIED
