Hi,You can create a Temp file dynamically write on it  from PDF writer and use that in attachment , something like below  
File file = FileUtil.createTempFile("pdf");
OutputStream os = null;
        try {
            os = new FileOutputStream(file);
        } catch (FileNotFoundException e) {
            _log.error(e.getMessage());
        }

PdfWriter writer = null;
        try {
            writer = PdfWriter.getInstance(document, os);
        } catch (com.itextpdf.text.DocumentException e) {
            _log.error(e.getMessage());
        }

Hello Yasin , 
Thanks for your valuable suggestions . 

I tried this approach , It working fine .. But we any other alternate because we dont want to store the file in server . In this code we are creating tempFile i.e. always storing in server .

Thnak & Regards ,

Looking at MailMessage, it seems to be limited so that you can only add attachments from a file - To generate in memory you'd go with e.g. BufferedOutputStream, but MailMessage's interface always assumes that there's a file to attach.
You could go with the standard (javax) mail API instead of Liferay's, but you'd be missing the mail to be asynchronously sent.
