Apache POI - the Java API for Microsoft Documents.
The Apache POI Project’s mission is to create and maintain Java
APIs for manipulating various file formats based upon the Office
Open XML standards (OOXML) and Microsoft’s OLE 2 Compound Document
format (OLE2). In short, you can read and write MS Excel files
using Java. In addition, you can read and write MS Word and MS
PowerPoint files using Java. The project has recently added
support for Outlook (HSMF), which allows reading Outlook MSG
files. At this time, it provides simple read access to some of the
textual content of MSG files.

The jmbox project (read jambox) enables developers to use the
JavaMail API to manage mail stored in local repositories like
Outlook Express, Mozilla, Netscape, etc. A JavaMail enabled
application needs only to include the jmbox distribution jar in its
classpath to automatically benefit from local mail management, the
same way it would do with POP3 or IMAP remote mail. At the moment
jmbox supports navigation and reading from Outlook Express 5/6 mail
(dbx format). Writing into folders and support for other
repositories (mbox) will be added. Available at:

A sample application using the Devsphere Mapping Framework:
A servlet called FormMailer converts data collected with HTML
forms to objects and then to key-value pairs. The obtained ASCII
text is mailed to one or more addresses using JavaMail.
A standalone application called MailMonitor uses JavaMail to get
the messages from the mail server. Then, it converts the obtained
key-value pairs to objects, which are forwarded to a dynamically
loaded class for processing. The application is described in
Chapters 12-17 of the Developer’s Guide, available at
