The other option you might try (it's worked for me with great success) is to introduce an intermediary step...
Instead of the click invoking a servlet which generates a file that is instantly streamed back to the browser, instead have that link create a comma-seperated file on your server, and make sure it's got a *.csv extension. Then present the user with a 2nd link that is the 'download' link.
The link to serve this file will cause pretty much any version of IE past 5.0 to open Excel as the default application for files of type *.csv
This gets around the nastiness of having to set content-types, application mime stuff, and not to mention streaming a file back through the response.
If you want to create the Excel content as something other than a comma or tab separated file, there is a pure Java API for creating and manipulating Excel binaries under the Jakarta project: http://jakarta.apache.org/poi/hssf/index.html
