I have an application where i have to generate a file either it could be an txt file. All i want is to send some reports over mail either by mail or attachment in mail.

please help me how to do this?

The data format is something like a tabular format. 

//create a multi part
            Multipart mp = new Multipart();

            //data for the content of the file
            String fileData = "<html>just a simple test</html>";
            String messageData = "Mail Attachment Demo";

            //create the file
            SupportedAttachmentPart sap = new SupportedAttachmentPart(mp,"text/html","file.html",fileData.getBytes());

            TextBodyPart tbp = new TextBodyPart(mp,messageData);

            //add the file to the multipart
            mp.addBodyPart(tbp);
            mp.addBodyPart(sap);

            //create a message in the sent items folder
            Folder folders[] = Session.getDefaultInstance().getStore().list(Folder.SENT);

            Message message = new Message(folders[0]);

            //add recipients to the message and send
            try {
                 Address toAdd = new Address("nilanchala_p@spanservices.com","Nilanchala");
                 Address toAdds[] = new Address[1];
                 toAdds[0] = toAdd;
                 message.addRecipients(Message.RecipientType.TO,toAdds);
                 message.setContent(mp);

                 Transport.send(message);
            } catch (Exception e) {
                 Dialog.inform(e.toString());
            }

    The best way is to send the table using plain text with html formatting

    <table border="1">
    <tr>
        <td>row 1, cell 1</td>
        <td>row 1, cell 2</td>
    </tr>
    <tr>
        <td>row 2, cell 1</td>
        <td>row 2, cell 2</td>
        </tr>
</table>

    No need for a file… Just format and send

    Ok try this:

    //create a multi part
            Multipart mp = new Multipart();

            //data for the content of the file
            String fileData = "<html>just a simple test</html>";

            //create the file
            TextBodyPart tbp = new TextBodyPart(mp,fileData );

            //add the file to the multipart
            mp.addBodyPart(tbp);

            //create a message in the sent items folder
            Folder folders[] = Session.getDefaultInstance().getStore().list(Folder.SENT);

            Message message = new Message(folders[0]);

            //add recipients to the message and send
            try {
                 Address toAdd = new Address("nilanchala_p@spanservices.com","Nilanchala");
                 Address toAdds[] = new Address[1];
                 toAdds[0] = toAdd;
                 message.addRecipients(Message.RecipientType.TO,toAdds);
                 message.setContent(mp);

                 Transport.send(message);
            } catch (Exception e) {
                 Dialog.inform(e.toString());
            }
