Examples with Unmarshaller javax.xml.bind.Unmarshaller used on opensource projects

Example 1 with Unmarshaller

use of javax.xml.bind.Unmarshaller in project camel by apache.

the class CamelContextAddRouteDefinitionsFromXmlTest method parseUri.

protected Object parseUri(String uri) throws JAXBException {
    Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
    URL resource = getClass().getResource(uri);
    assertNotNull("Cannot find resource on the classpath: " + uri, resource);
    Object value = unmarshaller.unmarshal(resource);
    return value;
}

Example 2 with Unmarshaller

use of javax.xml.bind.Unmarshaller in project camel by apache.

the class RestContextRefDefinitionHelper method cloneRestDefinition.

Example 3 with Unmarshaller

use of javax.xml.bind.Unmarshaller in project camel by apache.
