Unable to extract binary attachment correctly

[Ashfaq Framewala]

Hi,

I have an application which sends SOAP message over JMS (TIBCO EMS). This SOAP message contains a binary attachment (swa). I have written following Java code to extract the binary attachment but when I write this attachment to a file, the file format is corrupted and size of the output file generated is different from what is sent as an input. Can you please help in finding out what is wrong with this code?

	public static AttachmentDetails parseSOAPEnv(String inputMessage, String boundary, String binaryContent) throws SOAPException, IOException {
		
		// Create SoapMessage
    	Attachment[] attachmentList = null;
    	AttachmentDetails attList = new AttachmentDetails();

	        MessageFactory msgFactory     = MessageFactory.newInstance();  
	        MimeHeaders hdrs = new MimeHeaders();
	        //System.setProperty("mail.mime.multipart.ignoreexistingboundaryparameter", "true");	        
	        hdrs.addHeader("Content-Type", "multipart/related; boundary=\"" + boundary + "\"");
	        
	        byte[] buffer                 = inputMessage.getBytes();
	        ByteArrayInputStream stream   = new ByteArrayInputStream(buffer);  
	        SOAPMessage message           = msgFactory.createMessage(hdrs, stream);  
	        
	        //System.out.println(soapPart.getEnvelope().toString());
	        int countAttachments = message.countAttachments();
	        System.out.println("Attachments = " + countAttachments);
	        if (countAttachments == 0) return null;
	        Iterator attachmentIterator = message.getAttachments();
	        attachmentList = new Attachment[countAttachments];
	        int idx = 0;
	        while(attachmentIterator.hasNext()) {
	        	Attachment attachmentData = new Attachment();
	        	AttachmentPartImpl attachmentPart = (AttachmentPartImpl)attachmentIterator.next();
	        	Iterator mimeHeaders = attachmentPart.getAllMimeHeaders();
	        	while(mimeHeaders.hasNext()) {
	        		MimeHeader mimeHeader = (MimeHeader)mimeHeaders.next();
	        		System.out.println("#### Mime header : " + mimeHeader.getName() + " = " + mimeHeader.getValue());
	        		attachmentData.getMimeHeader().getListOfHeaderNames().add(mimeHeader.getName());
	        		attachmentData.getMimeHeader().getListOfHeaderValues().add(mimeHeader.getValue());
	        	}
	        	if (attachmentPart.getContentType().compareTo("text/plain") == 0  ||
	        			attachmentPart.getContentType().compareTo("text/xml") == 0) {
	        		attachmentData.setAttachmentContent(attachmentPart.getContent().toString());
	        	}
	        	else {
	        		System.out.println("Found binary attachment");
	        		//attachmentData.setAttachmentContent(Base64.encode(attachmentPart.getRawContentBytes()));

	        		if (attachmentPart.getContent() instanceof InputStream) {
	        			System.out.println("Input stream type");
	        			BufferedReader reader = new BufferedReader(new InputStreamReader((InputStream)attachmentPart.getContent()));
			        	StringBuilder sb = new StringBuilder();
			        	String line = null;
			        	while ((line = reader.readLine()) != null) {
			        		sb.append(line + "\n");
			        	}
			        	attachmentData.setAttachmentContent(sb.toString());	        			
		        		String attachmentPartRaw = new String(attachmentPart.getRawContentBytes());
		        		attachmentData.setAttachmentContent(attachmentPartRaw);
				
	        		}
	        		else if (attachmentPart.getContent() == null) {
	        			System.out.println("Content is null");
	        			InputStream attachmentIS = attachmentPart.getBase64Content();
	        			ByteArrayOutputStream baos = new ByteArrayOutputStream();				
	        			byte[] bfr = new byte[1024];
	        			int read = 0;
	        			while ((read = attachmentIS.read(bfr, 0, bfr.length)) != -1) {
	        				baos.write(bfr, 0, read);
	        			}		
	        			baos.flush();
	        			attachmentData.setRawAttachmentContent(baos.toByteArray());
	        			OutputStream outputStream = new FileOutputStream("C:\\temp\\Output" + idx + ".jpg");
	        			baos.writeTo(outputStream);
		        		String attachmentPartRaw = new String(baos.toByteArray(), "UTF-8");
		        		attachmentData.setAttachmentContent(attachmentPartRaw);
		        	}	        		
	        	}
	        	attachmentList[idx] = attachmentData;
	        	idx++;
	        	//System.out.println(sb.toString());
	        	//System.out.println(attachmentPart.getContent());
	        }
	        // -- DONE  	
	        //message.writeTo(System.out);
	    attList.setAttachmentList(attachmentList);
    	return attList;
	}

Thanks for your help!
