Clicking on jnlp does not open java app

Problem:
By default, Microsoft's IIS mime extensions do not recognize .jnlp files. So clicking on jnlp links on a web page hosted by IIS will simply open a xml document, as best.

Solution:
In the container of the website hosting the .jnlp files, add a mime type/extension as follows.
extension: .jnlp
content type (mime): application/x-java-jnlp-file
