Sorry not good at English.
I use cxf for the first time.
Refer to the various sample, I tried to create a simple REST web service
with apache cxf.
I succeed when @Produces tag set "application/xml".
but failed when @Produces tag set "application/json" with [No message body
writer has been found for response class Document] message.
result is below
-------------------------------------------------------------------------------------
[when @Produces("application/xml")]
<document>
<name>aaa</name>
</document>
[when @Produces("application/json")]
No message body writer has been found for response class Document.
-------------------------------------------------------------------------------------
my code is below.
-------------------------------------------------------------------------------------
[Resource Interface class]
@Path("/document")
public interface DocumentResource {
@GET
@Path("/name/{name}")
@Produces("application/json")
Document getDocument(@PathParam("name") String name);
}
[Implement class]
@Component
public class DocumentResourceImpl implements DocumentResource {
public Document getDocument(String name) {
Document doc = new Document();
doc.setName(name);
return doc;
}
}
[Document class]
@XmlRootElement
public class Document {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
[applicationContext.xml]

What is the cause of this problem(code? configuration? library?)
Thank you.
