Background
The standard HttpServletRequest class is not capable of handling file input fields in an HTML form. If you use this class, you will only receive the file name as the parameter value and not the entire file itself. In this tutorial, I will show you how to create the HTML form and process the form data using the com.oreilly.servlet package.
Step 1: Creating the Form
To create a form with a file input field, you need two add 2 additional features to any form: an enctype attribute to the form tag and a file input field. Set the enctype as "multipart/form-data". Here is what the code would look like:
<form action="upload" id="upload" name="upload" enctype="multipart/form-data" method="post">
Name: <input type="text" name="name" id="name" />
Attachment: <input type="file" name="attachment" id="attachment" />
<input type="submit" value="submit" />
</form>
Download the jar file from the servlets.com website. Install the jar file to use with your project. (If you are using Eclipse, you can find instructions on how to install .jar files in your project here.)
Import the package at the top of your file.
import com.oreilly.servlet.*;
Create a new MultipartRequest object. The constructor can accept several parameters (see the API). I like to use the constructor accepting the following parameters: the HttpServletRequest from the doPost method, the path to the directory where file is to be saved, and the size limit of the files. If you do not specify a size limit of the files, a default of 1MB will be set.
MultipartRequest mpRequest = new MultipartRequest(request, "/Users/bob/project/attachments", 3000000);
Once the MultipartRequest object has been initialized, you can retrieve form data. Use the getParameter method to retrieve form input field data for all fields other than the file field. Use this method with the input field name as a parameter to retrieve the value of the field.
String name = mpRequest.getParameter("name");
For the file field, use the getFile method to retrieve the file uploaded in the file input field. Use the name of the file input field as a parameter. This method returns a file object, which is the file that was uploaded in the form. The file is saved in the directory specified when creating the MultipartRequest object.
File file = mpRequest.getFile("attachment");
That's about it! Simple, right? There are several other methods that you can use in the com.oreilly.servlet package, which are discussed in the API.
HTML emails can be hard to create since most of the tricks used to develop web pages are completely unusable when creating HTML emails. CSS is not well supported, images can be a disaster, and layout is best done using tables (gasp). www.MailChimp.com describes the situation quite nicely: "Think back to the old days of the web browser wars. When Netscape and Microsoft were duking it out. There was no Flash plugin. It was only shockwave. Put away your DIVs and DHTML. Dust off those tables, shim.gifs, and font tags, because you’re gonna need 'em."
Webmail servicesWebmail services strip the <html> <head> and <body> tags from an HTML email. Keep this in mind when coding emails.
Email widthSince most people view emails in a reading pane rather than full screen, set the email width at:
500-600 pixels
ImagesImages are not displayed immediately in all email clients (to name a few: Outlook 2003, Outlook Express, AOL, Gmail, Thunderbird) . The user has to allow the email client to display images before they are shown. Since this is the case, do the following when using images in emails:
Don't even think about it.
TablesDon't use div tags to position elements since some email clients strip div tags. Using tables for layout is probably the best way to create a well-formed email. www.MailChimp.com suggests using separate tables for the header, body, and footer of emails since some email clients do not handle colspan (Lotus Notes).
As noted above, Webmail services strip the <body> tag from an email. If you have a background color applied to the body tag, this will get stripped as well. Use a 100% wide table to hold your email and apply the background color to the table.
CSSThere is no standard support for CSS in today's email clients. No email clients allow for external style sheets, and, since Webmail services strip the portion of the email, it is best to place any style within the body of the email. In addition, CSS positioning is not supported by email clients.
To keep email style consistent throughout all email clients, review the following table :
| Email Client | Supports… |
|---|---|
| Yahoo! Mail | CSS |
| Hotmail | CSS |
| Outlook and Outlook Express | CSS |
| Gmail | Inline CSS |
| Lotus Notes | Inline CSS |
| AOL 9 | CSS |
| Thunderbird | CSS |
| Mac Mail | CSS |
| Entourage | CSS |
| Eudora for the Mac | No CSS |
