30.4. Adding Classes to the Runtime Marshaller
Overview
When the Apache CXF runtime reads and writes XML data it uses a map that associates the XML Schema types with their representative Java types. By default, the map contains all of the types defined in the target namespace of the WSDL contract's
schema element. It also contains any types that are generated from the namespaces of any schemas that are imported into the WSDL contract.
The addition of types from namespaces other than the schema namespace used by an application's
schema element is accomplished using the @XmlSeeAlso annotation. If your application needs to work with types that are generated outside the scope of your application's WSDL document, you can edit the @XmlSeeAlso annotation to add them to the JAXB map.
Using the @XmlSeeAlso annotation
The
@XmlSeeAlso annotation can be added to the SEI of your service. It contains a comma separated list of classes to include in the JAXB context. Example 30.7, “Syntax for Adding Classes to the JAXB Context” shows the syntax for using the @XmlSeeAlso annotation.
Example 30.7. Syntax for Adding Classes to the JAXB Context
import javax.xml.bind.annotation.XmlSeeAlso; @WebService() @XmlSeeAlso({Class1.class, Class2.class, ..., ClassN.class}) public class GeneratedSEI { ... }
Tip
In cases where you have access to the JAXB generated classes, it is more efficient to use the
ObjectFactory classes generated to support the needed types. Including the ObjectFactory class includes all of the classes that are known to the object factory.
Example
Example 30.8, “Adding Classes to the JAXB Context” shows an SEI annotated with
@XmlSeeAlso.
Example 30.8. Adding Classes to the JAXB Context
...
import javax.xml.bind.annotation.XmlSeeAlso;
...
@WebService()
@XmlSeeAlso({org.apache.schemas.types.test.ObjectFactory.class,
org.apache.schemas.tests.group_test.ObjectFactory.class})
public interface Foo {
...
}
