.jnlp is the file format for the 'Java Network Launch Protocol', of which Sun's Java Web Start is the reference implementation. It's just an xml file describing deployment and launching of a program. It should be associated with the Java Web Start executable (javaws).
If you click the .jnlp link on the site and all it does it open in a text editor or something else than start JEmu2, there is a few possibilities you could check:
1) Your version of java doesn't support JNLP (there is no program called 'javaws' in the JRE). I don't know which java distributions support java web start and which don't, but Sun's JRE does since version 1.4. I think as of Java5, java web start is part of the spec.
2) There could be something wrong with the association between the .jnlp's MIME type or file extension and the Java Web Start executable (javaws).
As an aside: it's always 'interesting' to see how java's portability is both its strength and its weakness.
