You create a multipart body and set the file
[CODE=java]
BodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart() ;
//....
// Set the normal text part
multipart.addBo dyPart(messageB odyPart);
messageBodyPart = new MimeBodyPart();
DataSource source = new FileDataSource( "yourfilePath.t xt");
messageBodyPart .setDataHandler (new DataHandler(sou rce));
messageBodyPart .setFileName(fi lename);
multipart.addBo dyPart(messageB odyPart);[/CODE]

You are uploading the file to the server right? You can use a ByteArrayDataSo urce instead of a FileDatasource if you are getting the file as a byte[].

but how do i get the filename?

String filename = mrequest.getPar ameter("file");
returns null

If you have a the file in a byte[] on the server side then you don't need a file path. You would just use the ByteArrayDataSo urce which you create from the byte[]. How are you uploading the file to the server?

Code:

        

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <link rel="stylesheet" type="text/css" href="css.css"/>
        <title>HRMailer</title>
    </head>
    <body>
       <table width="900">

       <table> <form action="send.jsp" method="post" enctype="multipart/form-data">

           <tr><td>Subject:</td>
               <td><input type="text" name="subject" value=""><td>
           </tr>
           <tr>
               <td>From</td>

           <tr>

        </td>

and then

Code:

Session session = Session.getDefaultInstance(properties);

    
         // Create a default MimeMessage object.
         MimeMessage message = new MimeMessage(session);

         // Set From: header field of the header.
         message.setFrom(new InternetAddress(from));

         // Set To: header field of the header.
         message.addRecipient(Message.RecipientType.TO,
                                  new InternetAddress(to));

         // Set Subject: header field
         message.setSubject(subject);

         // Create the message part 
         BodyPart messageBodyPart = new MimeBodyPart();

         // Fill the message
         messageBodyPart.setText(body);
         
         // Create a multipar message
         Multipart multipart = new MimeMultipart();

         // Set text message part
         multipart.addBodyPart(messageBodyPart);

         // Part two is attachment
         messageBodyPart = new MimeBodyPart();
         String filename = mrequest.getParameter("file");
         DataSource source = new FileDataSource(filename);
         messageBodyPart.setDataHandler(new DataHandler(source));
         messageBodyPart.setFileName(filename);
         multipart.addBodyPart(messageBodyPart);

         // Send the complete message parts
         message.setContent(multipart );

         // Send message
         Transport.send(message);
         System.out.println("Sent message successfully....");
}
   }
      catch (MessagingException ex) {
         ex.printStackTrace();
      }

As I explained in your thread http://bytes.com/topic/java/answers/...variables-null
Read about how to upload files to the server side in java first. Google is your friend.

**oll3i** · Oct 3 '13, 09:11 AM

Code:

 if(ServletFileUpload.isMultipartContent(request)){
            
                List<FileItem> multiparts = new ServletFileUpload(
                                         new DiskFileItemFactory()).parseRequest(request);
               
                for(FileItem item : multiparts){
                    if(!item.isFormField()){
                        String file = new File(item.getName()).getName();
                        item.write( new File(UPLOAD_DIRECTORY + File.separator + file));
                    DataSource source = new FileDataSource(UPLOAD_DIRECTORY + File.separator +file);
         messageBodyPart.setDataHandler(new DataHandler(source));
         messageBodyPart.setFileName(file);
                    
                    }
                }
         }

it does not upload the file
email sends without any error but does not come to email account.
