It works
@Override
public String toString() {
Client c = Client.create();
Providers ps = c.getProviders();
MessageBodyWriter mbw = ps.getMessageBodyWriter( CamembertVO.class,
CamembertVO.class, null, MediaType.APPLICATION_JSON_TYPE);
OutputStream out = new ByteArrayOutputStream();
try {
mbw.writeTo( this, CamembertVO.class, CamembertVO.class, null,
MediaType.APPLICATION_JSON_TYPE, null, out);
} catch (WebApplicationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
return out.toString();
}
thanks
