SOAP With Attachment with Java, working example

This code actually works , and produces a SOAM message with attachment of type application/octet-stream - which is totally acceptable, even if I would have preferred application/pdf.

import javax.xml.soap.*;
import java.net.URL;
import java.io.*;
import org.xml.sax.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import javax.activation.*;


// now all the SOAP code
MessageFactory factory = MessageFactory.newInstance();
SOAPMessage message = factory.createMessage();
SOAPPart soapPart = message.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPHeader header = envelope.getHeader();

DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
dbFactory.setNamespaceAware(true);
DocumentBuilder builder = dbFactory.newDocumentBuilder();
// add the SOAP body as from text
StringReader sr = new StringReader(textToSend);
InputSource is = new InputSource(sr);
Document document = builder.parse(is);
SOAPBody body = envelope.getBody();
SOAPBodyElement docElement = body.addDocument(document);
// add attachment from file          

String filename = theBUSINESSIDVALUE.split("\\^")[0];
File fileAttachment = new File(rootFolderForMSS + filename + ".pdf");
FileDataSource fds = new FileDataSource(fileAttachment);
DataHandler dh = new DataHandler(fds);
out.write("content-type=" + dh.getContentType() + "
");

AttachmentPart attachment = message.createAttachmentPart(dh);

String contentId = "<" + filename + ".pdf>";
attachment.setContentId(contentId);
message.addAttachmentPart(attachment);


SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapConnectionFactory.createConnection();
java.net.URL endpoint = new URL(POSTTOURL);
SOAPMessage soapResponse = connection.call(message, endpoint);

I had tried this one before:

AttachmentPart attachment = message.createAttachmentPart();

String filename = theBUSINESSIDVALUE.split("\\^")[0];
File fileAttachment = new File(rootFolderForMSS + filename + ".pdf");
byte[] fileData = new byte[(int) fileAttachment.length()];
DataInputStream dis = new DataInputStream(new FileInputStream(fileAttachment));
dis.readFully(fileData);
dis.close();
  
String contentId = "<" + filename + ".pdf>";
attachment.setContent(new ByteArrayInputStream(fileData), "application/pdf");
attachment.setContentId(contentId);
message.addAttachmentPart(attachment);

but it was failing with this error

I would rather say that it could be all a LOT simpler.... Java Java...too verbose...
