Adding file attachments to email

Here is a code snippet which adds file attachments to emails. 

For this we use the EmailFileAttachement object and add it to the EmailOptions when sending.

EmailTemplate emailTemplate = context.getObject( EmailTemplate.class, "some email template" );

EmailOptions emailOptions = new EmailOptions();

// This fictional method would return a String to

// set the fileName of the attachment.

String fileName = getFileName();

// This fictional method would return a byte[] to

// set the data of the attachment.

byte[] fileData = generateCsvFile();

EmailFileAttachment attachment = new EmailFileAttachment( fileName, EmailFileAttachment.MimeType.MIME_CSV, fileData );

emailOptions.addAttachment( attachment );

context.sendEmailNotification( emailTemplate, emailOptions );

Note: This was written for IdentityIQ 6.2. Other versions may vary.

Any good examples of how to convert the data to byte[] ?  I'm hoping to do this without having to add on any third-party libraries.

I found a working solution to my own question:

import java.io.File;
import java.io.FileInputStream;

   public static byte[] readFiletoByteArray(File file)  
   {     
    FileInputStream fileInputStream = null;     
    byte[] byteFile = new byte[(int) file.length()];     
    try     
    {             
     fileInputStream = new FileInputStream(file);        
     fileInputStream.read(byteFile);        
     fileInputStream.close();        
     for (int i = 0; i < byteFile.length; i++)        
     {           
    System.out.print((char) byteFile[i]);        
     }     
    }     
    catch (Exception e)     
    {        
  e.printStackTrace();     
    }     
    return byteFile;  
   }

Why oh why are image Mime types not supported??

Would be super handy for embedding images in email :smileyhappy:

I have a custom workflow successfully generating PDF files as attachments.  However, when I try to open them with Adobe Reader, I get a message to the effect that the file cannot be opened "because it is either not a supported file type or it has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded)."  They clearly show as a PDF but won't open with Adobe Reader.  However, they do open as text files in NotePad++.

This is the code I am using:

EmailTemplate emailTemplate = context.getObject( EmailTemplate.class, "EmailTemplateName" );

EmailOptions emailOptions = new EmailOptions();

String fileName = "FileName" + ".pdf";

String fileString = "Data goes here.";

byte[] fileData = fileString.getBytes("UTF-8"); //Does this need to be a different charset?

EmailFileAttachment attachment = new EmailFileAttachment( fileName, EmailFileAttachment.MimeType.MIME_PDF, fileData );

emailOptions.addAttachment( attachment );

context.sendEmailNotification( emailTemplate, emailOptions );

I tried changing the code to specify CSVs and TXT files, and they worked without any problems.  I have tried various other charsets in the getBytes() method without any luck either.  Any thoughts on additional steps to get the PDFs to open properly in Adobe Reader?

In place of

byte[] fileData = generateCsvFile();

this should work:

byte[] fileData = java.nio.file.Files.readAllBytes(file.toPath())

or

byte[] fileData = java.nio.file.Files.readAllBytes(java.nio.file.Paths.get(filePathStr));

This was very useful.  I was able to use the example to add attachments in my email notification. For the namin gof the attachment, I am currently renaming based on the lastName, firstName variables.  Is there a way to automatically add a new character to each attachment?  For example, I am sending 3 attachments in the email.  I would like the attachments to be renamed and show up in the email as:

lastName, firstName_1.pdf

lastName, firstName_2.pdf

lastName, firstName_3.pdf

Hi Experts,

Currently I have a certification campaign running and it will send an email reminder to the manager every 7 days using default email templete by SailPoint "Certification Reminder". I am trying to enhance the email template so the email can send with a PDF attachment. The PDF attachment is an existing PDF in SailPoint server. Any good example to achieve this?
