MIME types on the application server
When you open or download a file, the MIME type of a file
is retrieved from the application server. Most application servers,
including WebSphere® Application Server and
Tomcat, are configured with default MIME types. Some common file formats
are missing from the typical defaults for these application servers. If
a MIME type is not set for a particular file extension, artifacts
and attachments with that extension might open with the wrong program
or might be saved with an incorrect file extension.
For example, if a Microsoft Word document opens in the web browser as unreadable text, or if a .jar file is downloaded as a file with a .zip extension, the MIME types for these file extensions are not configured on the application server. In the first case, configure the extensions .doc and .docx with the MIME type application/msword. In the second case, configure the .jar extension with the MIME type application/x-jar.

Refer to the online help for your application server for complete instructions on configuring MIME types.
