Below is the java code that is written that is not working to embed the attachments in .eml file. The attachment are mainly .pdf files:-

PublicAPI tools = ThreadContainer.get().getPublicAPI();

try {

 javax.mail.Message message = new javax.mail.internet.MimeMessage(javax.mail.Session.getInstance(System.getProperties()));

  ClipboardPage mypage = tools.findPage("WorkAttachments");

ClipboardProperty WrkAttList = mypage.getProperty("pxResults");

  java.util.Iterator Attlist = WrkAttList.iterator();

    ClipboardPage thisAttachment = null;

message.setFrom(new javax.mail.internet.InternetAddress(From));

message.setRecipients(javax.mail.Message.RecipientType.TO,

javax.mail.internet.InternetAddress.parse(To));

message.setSubject(Subject);

// create the message part

javax.mail.internet.MimeBodyPart content = new javax.mail.internet.MimeBodyPart();

// fill message; body is String type

//content.setText(Body);

  content.setContent(Body,"text/html");

message.setContent(Body, "text/html");

javax.mail.Multipart multipart = new javax.mail.internet.MimeMultipart();

multipart.addBodyPart(content);

while (Attlist.hasNext())

                {

      //messages= "am in while block";

      thisAttachment = ((ClipboardProperty) Attlist.next()).getPageValue();

       byte[] docContentByteArray = Base64Util.decodeToByteArray(thisAttachment.getString("pyAttachStream"));

       fileName = thisAttachment.getString("pxAttachName");

      HashStringMap aMap = new HashStringMap();

      aMap.put("ContentDisposition","inline");

//Converting the bytestream to physical file and store it in service directory

     String result=tools.sendFile(docContentByteArray,fileName,true,aMap,false);

      javax.mail.internet.MimeBodyPart attachments = new javax.mail.internet.MimeBodyPart();

      String filepath ="file://web:/StaticContent/global/ServiceExport/"+fileName;

// Taking the physical file and embedding in the .eml file.

      javax.activation.DataSource source = new javax.activation.FileDataSource(filepath);

      attachments.setDataHandler(new javax.activation.DataHandler(source));

      attachments.setFileName(fileName);

      multipart.addBodyPart(attachments);

}

message.setContent(multipart);

message.writeTo(

new java.io.FileOutputStream(new java.io.File("WOEmailAttachment.eml")));

System.out.println("End of try block");

//anopther java for

  java.io.InputStream is = new java.io.FileInputStream("WOEmailAttachment.eml");

  java.io.ByteArrayOutputStream baos = new java.io.ByteArrayOutputStream(is.available());

  org.apache.commons.codec.binary.Base64OutputStream baos2 = new org.apache.commons.codec.binary.Base64OutputStream(baos);

byte[] buffer = new byte[4096];

 int bytesRead = 0;

while ((bytesRead = is.read(buffer, 0, 4096))!=-1) {

 baos2.write(buffer, 0, bytesRead);

 }

baos.flush();

 baos.close();

 is.close();

ClipboardPage attachPage = tools.findPage("pyNewFileAttachment");

ClipboardProperty attachStream = attachPage.getProperty("pyAttachStream");

attachStream.setValue(baos.toString());

  //end

} catch (Exception e) {

System.out.println("In catch block");

System.out.println(e.getMessage());

}
