Proper MIME media type for JNLP files

When working with JNLP files, I've run across the MIME type

application/x-java-jnlp-file

However I am not sure it is right, because

MIME types in the x- namespace are considered experimental

and it seems odd to me for JNLP.

This is the advice direct from Oracle in Setting Up the Web Site:

  1. Configure the Web server to use the Java Web Start MIME type

Configure the Web server so that all files with the .jnlp file extension are set to the application/x-java-jnlp-file MIME type.

Most Web browsers use the MIME type returned with the contents from the Web server to determine how to handle the particular content. The server must return application/x-java-jnlp-file MIME type for JNLP files in order for Java Web Start to be invoked.

Each Web server has a specific way in which to add MIME types. For example, for the Apache Web server you must add the following line to the .mime.types configuration file:

   application/x-java-jnlp-file JNLP

Check the documentation for the specifics of your Web server.
