JAXB marshaling issue with Camel and SMX 4.2

[Juan José Vázquez Delgado <ju...@gmail.com>]

Hi,

This weekend I bumped into an annoying issue regarding camel jaxb
marshaling in SMX 4.2. The issue had been discussed previously in the
Camel users list [1] but I couldn't find the right solution in it.

To make the long story short, a Camel JaxbDataFormat is unable to
create the JaxbContext from a bundle, even though it imports the
involved packages properly. A code like the next one doesn't work:

private JaxbDataFormat jaxb = new
JaxbDataFormat("my.package.with.jaxb.annotated.classes");

@Override
public void configure() throws Exception {		
    from("nmr:myNmrEndpoint")
	.marshal(jaxb)
            .to("log:out");
}

The package "my.package.with.jaxb.annotated.classes" contains an
ObjectFactory class and, as I said before, is exported and imported
properly. As it's discussed here [2], it's probably a classloading
issue but I don't know where it should be definitely solved.

So far, my workaround has been setting the jaxb context with the
classloader of the ObjectFactory class. Something like this:

@Override
public void configure() throws Exception {		

    JaxbDataFormat jaxb = new JaxbDataFormat();

    // I'd like getting rid of this
    ClassLoader cl =
my.package.with.jaxb.annotated.classes.ObjectFactory.class.getClassLoader();
    jaxb.setContext(JAXBContext.newInstance("my.package.with.jaxb.annotated.classes",
cl));

    from("nmr:myNmrEndpoint")
	.marshal(jaxb)
            .to("log:out");
}

This code works but an smarter approach would be fine.

Thanks in advance.

BR,

Juanjo.

Hi,

The same thing happens using the camel-soap component in SMX 4.3.0
FUSE 03-00. So far, my workaround has been:

SoapJaxbDataFormat soap = new SoapJaxbDataFormat("", new
ServiceInterfaceStrategy(PortType.class, true));
soap.setContext(JAXBContext.newInstance(MyFirstClass.class,
MySecondClass.class, ....));

Any ideas about how to avoid having to set the JAXB context class by class?

BR,

Juanjo.
