(Restlet 2.0.7 SE, running in Equinox, with Jetty extension, J2SE 1.6.0_11,
Ubuntu 10.04)
I am trying to use the JAXB extension (via ClientResource) to serialize some
DTO's. I definitely have all the bundles specified in lib/readme.txt for the
JAXB extension loaded, and everything resolves. However, I getting this error
(more detail below) when trying to put a DTO from client to server:
May 7, 2011 1:10:39 PM org.restlet.resource.UniformResource doCatch
WARNING: Exception or error caught in resource
java.lang.NoClassDefFoundError: javax/xml/transform/sax/SAXSource
at org.restlet.ext.jaxb.JaxbConverter.toObject(JaxbConverter.java:155)
at
org.restlet.service.ConverterService.toObject(ConverterService.java:158)
I thought javax.xml.transform.sax.SAXSource was available from the J2SE. The
API docs for J2SE 1.6 say it is.
----------
My DTO class is annotated with JAXB annotations and I do have an ObjectFactory
class as well as a jaxb.index in the same package:
@XmlRootElement(name="example", namespace="http://example.com/example";)
@XmlAccessorType(XmlAccessType.FIELD)
public class ExampleDTO
{
@XmlElement(required=true)
private String id;
public ExampleDTO()
{
super();
}
public String getId()
{
return id;
}
public void setId( String id )
{
this.id = id;
}
}
I have the following resource interface:
public interface ExampleResource
{
@Get("xml")
ExampleDTO retrieve();
@Put("xml")
void store( ExampleDTO dto );
}
that is implemented by a ServerResource class.
On the client, I have attempted to invoke the ExampleResource.store(ExampleDTO)
the following two ways:
ExampleDTO example = new ExammpleDTO();
example.setId( anId );
ClientResource clientResource = new ClientResource( uri );
clientResource.put( new JaxbRepresentation<ProgramDTO>(
MediaType.APPLICATION_XML, program ) );
and:
ExampleDTO example = new ExammpleDTO();
example.setId( anId );
ExampleResource exampleResource = new ClientResource( uri,
ExampleResource.class );
exampleResource.store( example );
In both cases, I get the same errors.
Client-side error:
