JSP - Problem sending form mail with attachment

Posted on 2008-10-09
Last Modified: 2013-11-24
I have an online email form which allows users to send an attachment. I have read through the following tutorials but I keep getting errors and I can't get my code to work.

The tutorial I have used are:

The errors I keep getting are:
An error occurred at line: 13 in the jsp file: /submit2.jsp
Generated servlet error:
Duplicate local variable session

An error occurred at line: 13 in the jsp file: /submit2.jsp
Generated servlet error:
The constructor MimeMessage(HttpSession) is undefined

Do I need to create a location on the server for the uploaded file first and then attach to the email OR is it possible for the file to be stored in memory when uploaded? I would prefer the second option if possible.

Can someone please help me out.

  String smtpServer = ""; // put here SMTP server address or IP you use for sending email



  // take the submitted form values from the request

  String fileName = request.getParameter("file1");  //this is the name of the file from the form field

  boolean sessionDebug = false;


  // create some properties and get the default Session

  Properties props = new Properties();

  props.put("", smtpServer);


  try {

  Session session = Session.getInstance(props, null);


  //create a message

  MimeMessage message = new MimeMessage(session);  

  InternetAddress from = new InternetAddress(fromAddress);


  InternetAddress to = new InternetAddress(toAddress);

  message.addRecipient(Message.RecipientType.TO, to);  



  // create the Multipart

  Multipart multipart = new MimeMultipart();


  // create part 1 and fill the first message part

  BodyPart mbpText = new MimeBodyPart();

  mbpText.setText("Melding til Sjøkartverket\n" + 

                  "Hva Slags type melding: " + hvaSlags +

		  "\nEpost: " + fromAddress); 



  // create part 2, attach file

  mbpText = new MimeBodyPart();  

  DataSource source = new FileDataSource(fileName);

  mbpText.setDataHandler(new DataHandler(source));




  // add the Multipart to the message



  // set the Date: header

  message.setSentDate(new Date());





  catch (MessagingException mex) {

       // Prints all nested (chained) exceptions as well

	  System.out.println("ERROR SENDING EMAIL:"+ mex);

What you need to do is change the line 37 to
Session mysession = Session.getInstance(props, null)
and line 40 to
MimeMessage message = new MimeMessage(mysession);  

as the session variable is the default name used by the JSP HttpSession.

Many thanks Tomas,

I have tried your suggestion and I still get errors.  I can't see what the problem is

org.apache.jasper.JasperException: Exception in JSP: /mailer2.jsp:43

41:   //create a message
42:   MimeMessage message = new MimeMessage(s);  
43:   InternetAddress from = new InternetAddress(fromAddress);
44:   message.setFrom(from);  
45:   InternetAddress to = new InternetAddress(toAddress);
46:   message.addRecipient(Message.RecipientType.TO, to);

I have had a look at the manual.  

There is the setFrom(Address address) method which I have used in this form
     message.setFrom(new InternetAddress(fromAddress));

It has worked for emails without attachments.  Do you have any idea why?

Sorry, that's right, it does take InternetAddress as parameter. My mistake.

Print out the error that you are getting by catching the exception and use
System.out.println(ex.getMessage()); where ex is the Exception instance.

InternetAddress uses strict parsing so it WILL fail with an exception if the address is in wrong syntax. Make sure that the email address is valid.

Many thanks,

That worked.  Now I have another error:

org.apache.jasper.JasperException: Exception in JSP: /mailer2.jsp:77

75:   // create part 2, attach file
76:   mbpText = new MimeBodyPart();  
77:   DataSource source = new FileDataSource(fileName);
78:   mbpText.setDataHandler(new DataHandler(source));
79:   mbpText.setFileName(fileName);
80:   multipart.addBodyPart(mbpText);

On line 77, I have used the filename of the attachment  from the form field
           String fileName = request.getParameter("file1");  

What I want is to get the filename and the file as an attachment to the email.  I'm not quite show how to do this.

Do you have a simpler way to send form mail with an attachment?

Take a look at this example:

Change the lines 77 and 79 accordingly
That is to
FileDataSource source = new FileDataSource(fileName);
