A problem with Attachment using saaj

[mojo lai]

I wrote a program(TrySend1) to test attachment with saaj


TrySend1 call the servlet(TryReceive1) and TryReceive1 return a

soap message with attachment to it .

but In TrySend1 program , it can't see any attachment at all .

why ???

(p.s.I am sure that I add the attachment to the soap message response. because msg.countAttachments() return 1 )

following is my code

TrySend1

 
import... ;
 
public class TrySend1
{
    public TrySend1()
    {
        try
        {
 
            SOAPConnectionFactory soapConnectionFactory=SOAPConnectionFactory.newInstance();
            SOAPConnection connection=soapConnectionFactory.createConnection();
            
            MessageFactory factory=MessageFactory.newInstance();
            SOAPMessage message=factory.createMessage();
            
            SOAPHeader header=message.getSOAPHeader();
            header.detachNode();
            
            URL endpoint=new URL("http://localhost:8080/SaajSample/TryReceive1");
            SOAPMessage response=connection.call(message,endpoint);
            connection.close();
 
            [B][I]System.out.println(response.countAttachments()); // print out 0[/I][/B]
 
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
 
    public static void main(String[] args)
    {
        new TrySend1();
    }
}

TryReceive1

public class TryReceive1 extends HttpServlet
{
    static MessageFactory msgFactory = null;
 
  public void doPost(HttpServletRequest req, HttpServletResponse resp)  throws ServletException, IOException
  {
      try
      {   
          msgFactory = MessageFactory.newInstance();
 
          InputStream is = req.getInputStream();
 
          SOAPMessage msg = msgFactory.createMessage(new MimeHeaders(), is);
 
          resp.setStatus(HttpServletResponse.SC_OK);
 
          resp.setHeader("Content-Type","text/xml");
 
            DataHandler dataHandler = new DataHandler(new URL("file:///C:/tomcat/webapps/SaajSample/WEB-INF/classes/xd.jpg"));
            AttachmentPart attachment = msg.createAttachmentPart(dataHandler);
            attachment.setContentId("attached_image");
            attachment.setContentType("image/jpeg");
 
            msg.addAttachmentPart(attachment);
            
[I][B]          System.out.println(msg.countAttachments()); // print out 1 [/B][/I]
          OutputStream os = resp.getOutputStream();
 
          msg.writeTo(os);
          os.flush();
        }
      catch (Exception e)
      {
          e.printStackTrace();
      }
  }    
}

In cases like these it's useful to examine the SOAP that gets sent over the wire. Either a tool like tcpmon (comes with Axis) can show it, or you could save the server response to a file before sending it, and examine its contents.

[mojo lai]

I think I have examined the SOAP that gets sent over the wire

by using System.out.println(msg.countAttachments())

am I wrong ?? thank you.

That just tells you that the SOAP stack thinks that there is an attachment. What you need to find out is whether there is an attachment in the SOAP that is sent.
