I am sending emails with javamail with no problem(I use EJB 3.0), the problem is when i try to add some image to the html, by ussing a multipart approach. For some reason i get a FileNotFoundException. I dont know how to get the path to the .png image that is located at WEB-INF/resources/images.
Here is what i did:
Message message = new MimeMessage(mailSession);
// From: is our service
message.setFrom(new InternetAddress(from));
// To: destination given
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
message.setSubject("Uspijesna registracija");
// How to found at http://www.rgagnon.com/javadetails/java-0321.html
message.setContent(generateActivationLinkTemplate(), "text/html");
Date timeStamp = new Date();
message.setSentDate(timeStamp);
// Prepare a multipart HTML
Multipart multipart = new MimeMultipart("related");
// Prepare the HTML
BodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(generateActivationLinkTemplate(), "text/html");
multipart.addBodyPart(htmlPart);
// PREPARE THE IMAGE
BodyPart imgPart = new MimeBodyPart();
DataSource ds = new FileDataSource("logomailtemplate.png");
imgPart.setDataHandler(new DataHandler(ds));
imgPart.setHeader("Content-ID", "the-img-1");
multipart.addBodyPart(imgPart);
// Set the message content!
message.setContent(multipart);
Transport.send(message);
The text is coming from another method, that works correctly. I think the problem is in this line of code:
DataSource ds = new FileDataSource("logomailtemplate.png");
This is what the console says:
java.io.FileNotFoundException: logomailtemplate.png (The system cannot find the file specified)
How can i access that image? It is located in WEB-INF/resources/images I am stuck the hold day with this ill really appreciate a hand :)

-----------------------------------UPDATE 2-----------------------------------------
String fileName = "/WEB-INF/resources/images/logoemailtemplate.png";
InputStream stream = null;
ClassLoader classLoader = Thread.currentThread()
.getContextClassLoader();
if (classLoader == null) {
classLoader = this.getClass().getClassLoader();
}
//This line dont work!
stream = classLoader.getResourceAsStream(fileName);
DataSource ds = new URLDataSource(classLoader.getResource(fileName));
//DataSource ds = new FileDataSource(new File(classLoader // .getResource(fileName).toURI())); Also dont work. Also i tried both / and without /
One way of accomplishing this can be:
DataSource ds = new ByteArrayDataSource(getServletContext().getResourceAsStream("WEB-INF/resources/images/logomailtemplate.png") ,mimeType);
getServletContext().getResourceAsStream() is received from a HttpServlet and returns an InputStream.
Better yet do this
String fileName = "/WEB-INF/resources/images/logomailtemplate.png";
InputStream stream = getServletContext().getResourceAsStream(fileName); //or null if you can't obtain a ServletContext
if (stream == null) {
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
if (classLoader == null) {
classLoader = this.getClass().getClassLoader();
}
stream = classLoader.getResourceAsStream(fileName);
}
DataSource ds = new ByteArrayDataSource(stream, "image/*");
Update
Alternatively
String fileName = "WEB-INF/resources/images/logomailtemplate.png";
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
if (classLoader == null) {
classLoader = this.getClass().getClassLoader();
}
DataSource ds = new FileDataSource(new File(classLoader.getResource(fileName).toURI()));
//OR
DataSource ds = new URLDataSource(classLoader.getResource(fileName));
Make sure your fileName starts with "/".
