    text
    copied!<p>I have to use an interface in my REST web service. Here is the Interface Specs.java :</p> <pre><code>@XmlJavaTypeAdapter(MyAdapter.class) public interface Specs { public BaseProperties getBaseProps(); public void setBaseProps(BaseProperties baseProps); } </code></pre> <p>MyAdapter.java :</p> <pre><code>public class MyAdapter extends XmlAdapter&lt;Object,Object&gt; { public Object unmarshal(Object v) { return v; } public Object marshal(Object v) { return v; } } </code></pre> <p>RegSpecs.java</p> <pre><code>@XmlType public class RegSpecs implements Specs{ private BaseProperties baseProps; public BaseProperties getBaseProps() { return baseProps; } public void setBaseProps(BaseProperties baseProps) { this.baseProps = baseProps; } } </code></pre> <p>MapSpecs.java</p> <pre><code>@XmlType public class MagSpecs implements Specs { private BaseProperties baseProps; private Features features; public BaseProperties getBaseProps() { return baseProps; } public void setBaseProps(BaseProperties baseProps) { this.baseProps = baseProps; } public Features getFeatures() { return features; } public void setFeatures(Features features) { this.features = features; } } </code></pre> <p>Accessing this service throws the following error :</p> <blockquote> <p>javax.xml.bind.MarshalException - with linked exception: [javax.xml.bind.JAXBException: class entities.MagSpecs nor any of its super class is known to this context.]</p> </blockquote> <p>How to modify my context ? I am using JAXB bundled with Jersey 1.5</p> <p>Thanks !</p> <p>EDIT : In an attempt to update my context, I added this code to my client (resource) class :</p> <pre><code>public class BookService implements ContextResolver&lt;JAXBContext&gt; { private JAXBContext jaxbContext; public BookService() { try { // Bootstrap your JAXBContext will all necessary classes jaxbContext = JAXBContext.newInstance(Specs.class,MagSpecs.class, RegSpecs.class); } catch(Exception e) { throw new RuntimeException(e); } } public JAXBContext getContext(Class&lt;?&gt; clazz) { if(BookService.class == clazz) { return jaxbContext; } return null; } </code></pre> <p>In this case I get error :</p> <blockquote> <p>entities.Specs is an interface, and JAXB can't handle interfaces. this problem is related to the following location: at entities.Specs entities.Specs does not have a no-arg default constructor. this problem is related to the following location: at entities.Specs</p> </blockquote>
