Subject RE: where to assert multipart requirements for jms transport
Date Tue, 24 Feb 2004 19:09:47 GMT

Thanks so much for your response!

For now, (as you suggested) I'm setting a jms property
in the header in JMSSender and picking it up in SimpleJMSWorker.
This fixes my tests for sending various types. I still need to
look into where to provide for multipart return types.

In JMSSender:
	// If the request message contains attachments, set
	// a contentType property to go in the outgoing message header
    String ret = null;
    Message message = msgContext.getRequestMessage();
    Attachments mAttachments = message.getAttachmentsImpl();
    if (mAttachments != null && 0 != mAttachments.getAttachmentCount()) {
        String contentType = mAttachments.getContentType();
        if(contentType != null && !contentType.trim().equals("")) {
            props.put("contentType", contentType);

In SimpleJMSWorker:
    String contentType = null;
    try { 
        contentType = message.getStringProperty("contentType");
        System.err.println("contentType = "+contentType);
    } catch(Exception e) { /* ignore */ }

    Message msg = null;
    if(contentType != null && !contentType.trim().equals("")) {
        MimeHeaders header = new MimeHeaders();
        header.addHeader("Content-Type", contentType);
        msg = new Message(in, true, header);
    } else {
        msg = new Message(in);

Thanks again!
