How to pass SOAP Attachments with JAX-RPC Web Service

Question

I'm confused...
This sample shows how to send/receive SOAP attachments by using the JAX-RPC Handler mechanism. Can somebody confirm if this is the preferred way to do this. I've seen an example wich does something like:
  public interface AttachmentService extends Remote {
    public String storeDocumentService(javax.activation.DataHandler dh, String filename) throws RemoteException;
  }and then uses JAX-RPC utilities to create wsdl, stubs and stuff. Does this have the same result, as what the OTN example shows (from an architecture perspective?
Thx,
Jan.

Answer 1

Well, how an attachment is processed depends on your application logic...if your application logic requires to processing attachments and verify it before processing the SOAP message, handlers could be better option.
If you need to process the attachment while processing the SOAP message, you can do it in the service implementation class.
In both the cases you need to get access to SOAPMessage object and from there get the attachments with getAttachments method.
