Struts FormFile to java.io.File

[Tim Storms]

Hi all,

In my application, people have to select a file (a struts FormFile) in a form. After the file was submitted, it should be send as an attachment in a mail. I'm using the Javamail package to send mails.

The problem I'm facing is that I can't cast the FormFile to a java.io.File which is needed by the JavaMail package. Do you have any idea how to do that?

Here's the code I use to attach a file to a mail:

private Message setAttachment(Message message) throws MessagingException {
MimeBodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
 
// the variable attachment should be a File instead of a FormFile    
DataSource source = new FileDataSource(attachment);
    
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(attachment.getName());
multipart.addBodyPart(messageBodyPart);
   
message.setContent(multipart);
    
return message;
}

I've been to fast. Here's the solution:

BulkBean bulkBean = (BulkBean) session.getAttribute("bulkBean");
FormFile bulkUpload = bulkBean.getBulkUpload();
File file = new File(bulkUpload.getFileName());

OutputStream os = new FileOutputStream(file);
InputStream is = new BufferedInputStream(bulkUpload.getInputStream());
int count;
byte buf[] = new byte[4096];

while ((count = is.read(buf)) > -1) {
os.write(buf, 0, count);  
}

is.close(); 
os.close();
